It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
As shown in fig. 1-6, the method for improving the passive safety of the non-bearing passenger car comprises the following steps:
1. two-stage crushing type vehicle frame.
The frame of the non-bearing passenger car is designed in strength, an energy absorption area is arranged at the front end of the frame, and a folding buffer area is arranged at the position of the frame corresponding to the rear end of the cab. The energy absorption zone of the frame is provided with an energy absorption box for absorbing collision energy and buffering collision strength, so that the car body after an accident is decelerated under relatively small deceleration. A folding buffer area is arranged on the frame at the rear end of the cab, and after the front-end energy absorption box is completely crushed, the deceleration peak value of the vehicle body is further reduced through deformation of the folding buffer area. The deceleration of the car body when the passenger car is in a frontal collision accident is reduced, the tension of the safety belt to the passenger is reduced, and the damage caused by the tension of the safety belt is further reduced. Through the design of frame intensity, ensure that the energy-absorbing area takes place to warp before folding buffer area, guarantee that the frame warp backward in proper order.
2. The front strength, middle strength and weakness can crush the car body framework.
The frame of department under the driver's cabin sets up to the non-deformation area, and the frame in non-deformation area has enough intensity, and after the collision accident took place, here frame does not take place to warp, guarantees that the driver's cabin structure is complete, is not by extrusion deformation. Because the two-stage crushing type frame is adopted in the first step, the folding buffer zone in the middle section of the frame is folded, the front end of the vehicle body is inevitably caused to move backwards along with the frame, and in order to ensure that the living space of a driver in a cab is not invaded, the weakening zone is arranged at the framework of the rear section in the vehicle body, the deformation of the vehicle body in the weakening zone is ensured, and the living space of the driver is ensured to be complete.
3. The five-point seat is fixed.
The passenger car seat is generally higher from the floor, and the passenger sits on the seat, and holistic barycenter is higher relative to the floor, and in case the passenger car takes place the frontal collision accident, the passenger is because inertia forward dashes, and the safety belt is transmitted passenger's impact force to the seat on, and the seat receives very big forward force, because the seat is higher from the floor, leads to the moment that the seat overturns forward great. If the seat attachment points are all located on the floor, such a large moment can cause the seat rear attachment points to fail and disengage, thereby causing the occupant to dive forward to strike the front seat and cause significant head and neck injuries. In order to improve the fixing strength of the seat, the invention adopts a mode of jointly fixing the seat by the floor and the side wall, wherein two fixing points are arranged on the floor, three fixing points are arranged on the side wall, one front end is arranged in the three fixing points of the side wall, and two rear ends are arranged. By arranging the seat fixing points in this way, the mass centers of the passengers and the whole seat are closer to the fixing points, and the forward overturning moment in the collision accident is effectively reduced.
Through the comprehensive effect of the three steps, the passive safety of the non-bearing passenger car is improved, the living space of a driver is ensured to be complete and not to be invaded, and the injury of rear passengers in the carriage is reduced.
The frame strength of the invention is arranged in a segmented way, the front-end energy absorption box is the weakest, the frame strength under the cab is the strongest, and the rear folding buffer zone is the next smallest. When the passenger car collides with the front surface, the energy-absorbing box is crushed and deformed firstly, and then the energy-absorbing box is folded to form a buffer area, and the non-deformation area is not crushed or folded. The weakening area is arranged in the rear area of the vehicle body cab, and weakening induction ribs are additionally arranged on the main structure, so that the strength of the weakening area is weaker than that of the cab at the front end. When the passenger car collides with the front surface, the weakening area behind the cab is deformed, the whole cab moves backwards, and the space in the cab is kept complete. The seats in the carriage are fixed by 5 points, 2 seats are positioned on the floor, and 3 seats are positioned on the side wall of the carriage.
Example 1
The embodiment is described based on a rigid wall collision of 32 km in front, and when a passenger car collides, the front end energy-absorbing box deforms, so that the deceleration of the car body is ensured not to exceed 20g, and in the whole collision engineering, the deceleration of the car body is ensured not to exceed 25g.
1. Firstly, designing a frame section:
the energy-absorbing box is crushed and deformed, the deceleration of the vehicle body is not more than 20g, and the sectional area A of the energy-absorbing box 1 The following conditions should be satisfied:
σ s1 ×A 1 ≤20×m×g
namely:
middle sigma s1 The yield strength of the material used for the energy-absorbing box is m is the total simulated mass of the passenger car, and g is the gravitational acceleration. Under the condition of structural permission, the length of the energy-absorbing box is as long as possible, so that the energy-absorbing time is as long as possible, and in the embodiment, the length of the energy-absorbing box is 130mm, and the cross section of the energy-absorbing box is in a closed 'mesh' shape.
The strength of the non-deforming area of the frame should be strong enough so that deformation does not occur during the whole collision course. The frame is welded into a shape of a Chinese character 'kou' by two steel plates with C-shaped cross sections, and the cross section area A 2 The following conditions need to be satisfied:
σ s2 ×A 2 ≥25×m×g
namely:
middle sigma s2 Is the yield strength of the material used for the frame.
In order to ensure that a folding buffer zone of the frame starts to fold after the energy absorption box is completely crushed and absorbs energy, the deceleration of the vehicle body is not higher than 25g, the folding buffer zone is formed by steel plates with C-shaped cross sections, and the cross section area A 3 The following conditions should be satisfied:
σ s1 ×A 1 ≤σ s2 ×A 3 ≤25×m×g
namely:
the cross-sectional force born by the vehicle body is ignored in the cross-sectional design of the vehicle frame, and is mainly due to the fact that the vehicle frame is a main bearing member before the folding and crushing zone is crushed and folded, and the impact force born by the vehicle body is relatively small.
2. Secondly, carrying out front collision simulation of the whole vehicle based on the cross section area of the frame:
the vehicle body deceleration waveform is shown in fig. 5. The front end energy absorption box of the frame is crushed and absorbed in the front 25ms, the deceleration is smaller than 20g, the folding buffer zone of the frame starts to fold, and the deceleration reaches the peak value of 24.4g at the moment of 32 ms. The non-deformation area of the frame is not deformed, the structure of the vehicle body cab is complete, and the living space of the driver is not invaded.
3. Finally, a simulation of the seat anchor point strength was performed based on fig. 5:
the front row of seats and the rear row of seats are arranged on the body of the passenger car, the HYBRID III type 50 percentile male mannequin is respectively arranged on the front row of seats and the rear row of seats, the front row of dummy wears safety belts, and the rear row of dummy does not wear safety belts. A forward initial velocity of 32kph was applied to the simulation model and a backward deceleration as shown in fig. 5 was applied to the vehicle body. The seat deformation is shown in fig. 6, and according to the simulation result, the seat fixing points are firm enough and have no failure falling-out risk.
In summary, when a front collision occurs in the passenger car, the cab is not deformed, the peak value of the deceleration of the car body is not more than 25g, and the seat is firmly fixed. The safety of a driver and rear passengers can be ensured, and the passive safety performance of the passenger car is effectively improved.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
