Step 301, immersion volume of the target object in liquid object is calculated.
Immerse the volume that volume refers to target object part below the surface of liquid object.It is travelled in waters with ship For, a part of ship is more than the water surface, and another part is in the water surface hereinafter, immersing volume is that a part below the water surface Volume.
Calculate immerse volume when, target object can be immersed in liquid object surface segmentation below at several three Edged surface (can be described as " immerse triangular facet ") then selects a reference point on the surface of liquid object, by the reference point respectively with Each vertex for immersing triangular facet is connected, several tetrahedrons (namely using reference point as the triangular pyramid on vertex) is obtained, according to each A tetrahedral volume can calculate immersion volume.
Step 302, it obtains and immerses the corresponding geometric center of volume.
That a part that target object is immersed in liquid object is a polyhedron, immerses the corresponding geometric center of volume As polyhedral geometric center.Since the quality of polyhedral different location is different, in polyhedral geometry The heart may be overlapped with polyhedral mass center.

In conclusion being subject in liquid object in technical solution provided by the embodiments of the present application due to target object Active force is calculated according to immersion volume, relative to the integration method based on upstream face piece that the relevant technologies provide, leaching The calculating for entering volume is relatively more simple, therefore can simplify the object computation complexity that physical motion is simulated in a liquid, subtracts Few calculation amount.
In addition, in the active force that simulated target object is subject in liquid object, other than considering buoyancy, it is also contemplated that Lift and resistance, so that the simulation to active force is more comprehensively true to nature.
In the following, explanation is introduced to the calculating process for immersing volume and its geometric center.
In the exemplary embodiment, the calculating process for immersing volume may include the following steps:
1, according to the apparent height of liquid object, each immersion triangular facet of target object is obtained；
It immerses triangular facet and refers to the triangular facet being immersed in liquid object on the surface of target object.By the table of target object Face is divided into multiple triangular facets, is the calculating for the ease of volume.
Any one triangular facet on the surface of target object is only possible in one of following three kinds of states: leaching completely Enter into liquid object and (enter water completely), be absolutely not immersed in liquid object (i.e. water outlet completely), be partially immersed in liquid In body object (i.e. a part enters water).By taking the triangular facet that tri- vertex A, B, C are constituted as an example, above-mentioned three kinds of states are divided Analysis:
(1) triangular facet is totally immersed in liquid object, its main feature is that tri- points of A, B, C are below the surface of liquid object Highly.If selecting a reference point P, reference point P to connect with tri- points of A, B, C to form four sides on the surface of liquid object Body, the tetrahedron are totally immersed in liquid object.At this point, the triangular facet that tri- points of A, B, C are constituted belongs to immersion triangular facet.
(2) triangular facet is absolutely not immersed in liquid object, its main feature is that tri- points of A, B, C are above liquid object Apparent height.At this point, the triangular facet that tri- points of A, B, C are constituted is not belonging to immerse triangular facet.
(3) triangular facet part is immersed in liquid object, its main feature is that some is lower than liquid object in tri- points of A, B, C Apparent height, some be higher than liquid object apparent height.This is divided into two kinds of situations again: two points are lower than the table of liquid object Face height (i.e. two are clicked and entered water), a point are lower than the apparent height of liquid object (i.e. one is clicked and entered water).
For the first case, two when clicking and entering water, as shown in figure 4, straight line L represents the water surface, it is assumed that A be located at the water surface with On, B and C is located at the water surface hereinafter, triangular facet ABC is divided into 3 triangles X, Y and Z, wherein triangle X is located at the water surface or more, It is not belonging to immerse triangular facet, triangle Y and Z are located at the water surface hereinafter, belonging to immersion triangular facet.
For second situation, one when clicking and entering water, as shown in figure 5, straight line L represents the water surface, it is assumed that A be located at the water surface with Under, B and C are located at the water surface or more, and triangular facet ABC is divided into 3 triangles X, Y and Z, wherein triangle X be located at the water surface hereinafter, Belong to immersion triangular facet, triangle Y and Z are located at the water surface or more, are not belonging to immerse triangular facet.
Therefore, available according to the positional relationship of each triangular facet on the surface of target object and liquid subject surface Each immersion triangular facet of target object.
2, reference point is selected on the surface of liquid object, calculates separately the four of the reference point and each immersion triangular facet formation The volume of face body；
The point that terminal can choose the surface that any one in target object is located at liquid object is as a reference point.It is optional Ground, the geometric center of terminal selection target object liquid subject surface subpoint, it is as a reference point.
As shown in fig. 6, reference point P is connected with each vertex of triangular facet ABC respectively, tetrahedron is formed.This is tetrahedral Volume ViIt can be calculated using following formula:
Wherein, u, v, w respectively indicate from reference point P to A, the vector of tri- points of B, C.When tri- vectors of u, v, w are counterclockwise When arrangement, reference point P is in the front of triangular facet ABC, ViIt is greater than 0；Conversely, when tri- vector arranged clockwises of u, v, w, Reverse side of the reference point P in triangular facet ABC, ViIt is less than 0.
3, above-mentioned each tetrahedral volume is added, obtains immersing volume.
That is, immersing volumeWherein, ViIndicate that reference point immerses the four sides that triangular facet is formed with i-th The volume of body, n indicate the quantity of immersion triangular facet, and n is positive integer, and i is the positive integer less than or equal to n.
Optionally, the calculating process for immersing the corresponding geometric center of volume may include the following steps:
1, above-mentioned each tetrahedral geometric center is obtained respectively；
Still by taking tetrahedron shown in fig. 6 as an example, the tetrahedral geometric center CiIt can be calculated using following formula It arrives:
2, it using each tetrahedral volume as weight, according to each tetrahedral geometric center, calculates and immerses volume pair The geometric center answered.
It is calculated using following formula and immerses the corresponding geometric center C of volume:
Wherein, V indicates to immerse volume, ViIndicate that reference point immerses the tetrahedral volume that triangular facet is formed, C with i-thi Indicate that reference point immerses the tetrahedral geometric center that triangular facet is formed with i-th, n indicates to immerse the quantity of triangular facet, and n is positive Integer, i are the positive integer less than or equal to n.
It is provided by the above embodiment to calculate the method for immersing volume, it will be assumed that liquid subject surface is a horizontal plane, And target object and each intersection point of liquid subject surface are located in same level, this simplifies the calculating for immersing volume.But There is loss of significance in this, because liquid subject surface may be not a horizontal plane under actual conditions, such as to a certain extent There are waves.If this loss of significance can not be received, it may be considered that be projected out one towards liquid subject surface from triangle is immersed The not parallel prism in a top and bottom calculates volume.As shown in fig. 7, broken line L represents horizontal plane, the lower planes of prism are not In parallel.
In the following, explanation is introduced to the calculating process of each active force and torque.
1, the torque of buoyancy and buoyancy
In the exemplary embodiment, according to the density for immersing volume and liquid object, buoyancy is calculated.Optionally, according to Ah Base Mead principle calculates buoyancy F according to the following equationb:
Fb=ρ gV；
Wherein, ρ indicates the density of liquid object, and g indicates that acceleration of gravity, V indicate to immerse volume.
Buoyancy direction is that straight up, active position is immersing the corresponding geometric center of volume.When target object is in liquid When static in body object, the gravity being subject to is identical with buoyancy size, contrary.Due to immersing the corresponding geometry of volume Center is not always identical with the centroid position of target object, so buoyancy torque can be generated.
Optionally, according to buoyancy, the mass center of immersion volume corresponding geometric center and target object, the power of buoyancy is calculated Square.The torque T of buoyancy is calculated according to following formulab:
Tb=Fb×r；
Wherein, FbIndicate buoyancy, r is a vector, indicates the matter for immersing volume corresponding geometric center and target object The three-dimensional coordinate difference of the heart.
In actually calculating, discovery can be very unstable using buoyancy calculations torque, especially in the case where there is billow.Cause The calculation formula of above-mentioned buoyancy torque can be extended to following formula when actually calculating by this:
Tb=max (- mg, Fb)×r；
Wherein, m indicates the quality of target object, and g indicates acceleration of gravity.
Meanwhile in order to more freely debug the feel of buoyancy, we provide buoyancy torque parameter ParamTb, final floating The calculation formula of force square can be such that
Tb=((max (- mg, Fb)×r)RT×ParamTb)R；
Wherein, R indicate target object spin matrix, spin matrix be it is orthogonal, calculate when, directly use its transposition Buoyancy torque is calculated instead of inverting.
2, the torque of lift and lift
By taking target object is ship as an example, ship can allow water to form cyclic annular flow field around it when design, this Flow field may eventually form lift.When ship is mobile, fluid can be divided into two layers: one section by hull and flow close to hull, claim For upstream (upstream)；One section of outer layer in upstream flows, referred to as downstream (downstream) far from hull.Due to the water surface There is viscosity, downstream can be involved by the water flow of more bottom, and movement is slower.It thus can on the quarter form a gap, upstream This gap can be then filled, to form circulation.This circulation can form lift on ship bottom plate.
In the embodiment of the present application, lift is reduced to two parts.First part is according to lift formulaIt is calculated, wherein ρ indicates the density of liquid object, and C indicates the table of lift coefficient and target object Face shape and towards related, S indicates that immersion area of the target object in liquid object, v are indicated from the far place's liquid of target object The relative velocity of body object.In practical applications, it can be assumed that liquid object is that flow velocity, v are not the speed of target object. S is proportional to the contact area of target object Yu liquid subject surface, and it is long that immersion of the target object in liquid object can be used Degree is indicated multiplied by a definite value.Immersion length of the target object in liquid object, refers to target object and liquid Object table The distance between two contact points of head and the tail in face.Second part to immerse the square directly proportional of length, object can be allowed by doing so Body obtains rapidly enough lift after movement is got up in liquid object.
Comprehensive first part and second part above, according to the density of liquid object, the phase of target object and liquid object To the immersion length of speed and target object in liquid object, lift is calculated.Optionally, it calculates and rises according to following formula Power Fl:
|Fl|=ParamL1×l|v|2+ParamL2×l2；
Wherein, ParamL1It is the first constant item being calculated according to the density and lift coefficient of liquid object, ParamL2 It is the second constant item, v indicates that relative velocity, l indicate to immerse length.ParamL1And ParamL2It can configure.L can calculated When the immersion volume of target object, by the model space of the coordinate converting into target object of all immersion triangular facets, calculate It obtains.
Above-mentioned formula defines the size of lift, and the direction of lift is straight up.The same moment of lift.It is optional Ground calculates the torque of lift according to the mass center of lift and target object.
When target object is ship when calculating lifting force moment, the arm of force is defined as to the Model Space of target object Between along negative ship side direction unit vector.Assuming that+z is the front of model, then the torque T of available liftlAre as follows:
Tl=ParamTl×(Fl×([0 0 -1]R-massCenter))；
Wherein, ParamTlIndicate that lifting force moment coefficient, R indicate that the spin matrix of target object, massCenter indicate mesh Mark the mass center of object.
3, the torque of moving resistance and moving resistance
The object run in water will receive the moving resistance of water, according to the classical resistance equation in hydrodynamics:The moving resistance that object is subject in a fluid is F, and ρ is the density of fluid, and C is moving resistance coefficient, and S is Area of reference, the rectangular projection area being commonly defined as in the direction of motion, v is speed.As when calculating lift, it is assumed that water Flow velocity is the speed that 0, v is equal to ship.The size of S is proportional to the square root for immersing volume.
In addition, the moving resistance of water is also related with the situation of change of volume is immersed, when immersing volume increase, need More water are discharged；When immersing volume reduction, has water and be received in.Above-mentioned formulaIt is according to mesh The moving resistance for entering the calculating of regimen condition of mark object at some time point, it is also necessary to immerse body according between two neighboring time point Long-pending situation of change calculates additional moving resistance, complements each other between the two moving resistances.Optionally, according to leaching Enter the calculated moving resistance F of situation of change of volume are as follows:
