Description
Technical field
The present invention relates to a kind of positive pressure of shock wave test device.
Background technology
Shock wave pressure test is divided into two methods：A kind of electrical measuring method, one kind is Mechanical Method.Two methods respectively have excellent lack
Point, electrical measuring method can relatively accurately test out explosion wave superpressure value and Mechanical Method can more intuitively react different positions
Put the size of superpressure.
The measuring method of current positive pressure of shock wave, which is mainly, uses electrical measuring method, and electrical measuring method is that pressure sensor is placed on into blast
The scene of test, sensor will measure pressure signal and be converted to electric signal, arrive electric signal transmission through long electric wire or cable
The equipment such as preposition adapter, instantaneous signal recorder and the computer being disposed away from the blindage at scene, are finally completed data
Collection and storage.Its advantage is that the superpressure value accuracy measured is high, by being integrated meter to measured overpressure value and time
Calculation can obtain more accurate momentum value；Have the disadvantage that wiring is numerous and diverse, higher is required to space enrironment, for a wide range of, multiple spot
The test preparatory period is long, and cost is higher.
In recent years, with the development of various body detonation ammunitions, and for the damage effect test of the targets such as cabin, occur in that
On a large scale, the shock wave testing requirement of multiple spot, near field and particular surroundings is particularly a wide range of more to make up the deficiency of electrical measuring method
Point test wire performance difficulty, near-field test cable is easily damaged, and the target internal such as naval vessel is unsuitable for the place of lead measurement, just
More and more using mechanical diaphragm effect target mode come parameters such as measuring shock waves superpressures, its test result can be with electrical measuring method
Mutually check, injure power measurement for shock wave provides accurately and reliably means with evaluation.Its advantage is the change by observing diaphragm
Shape can more intuitively observe the size of diverse location superpressure, can be in cost, in operation, in practicality and reliability more
Mend that electrical measuring method specific environmental adaptability is poor, reliability is relatively low, be unfavorable for the shortcoming of multimetering, as one kind in test process
Simple and practical explosion wave parameter measurement and characterizing method, have the disadvantage the deflection and shock wave due to not yet setting up diaphragm
Precise relation between peak overpressure, quantitatively characterizing, accuracy assessment to its measurement result are remained in some problems.
Present superpressure test is typically used alone a kind of method to characterize the superpressure size of specified point position, not both
Advantage is complementary.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of explosion wave press method and electrical measuring method is integrated
Test device, explosive field certain position is placed into by device, pressure film and pressure sensor is installed by experiment demand, after detonation
The explosion wave of formation is propagated forward, and when shock wave skims over the test device, pressure sensor is converted to pressure signal
The pressure that electric signal symbolizes the point changes with time, and pressure film there occurs deformation under surge effect, pass through shape
Become the size that size represents pressure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of blast impulse mechanical effect target and superpressure are comprehensive
Test device is closed, including mounting bracket panel, mounting bracket bottom plate, pressure film and sensor install core.
Described mounting bracket bottom plate is rectangular configuration, and center is provided with manhole, and described pressure film tensioning is covered
Cover on through hole, and be mounted frame panel and be fixed；Some mounting holes are provided with around through hole, sensor is installed by sensor
Core is fixed in mounting hole.
The length of side of the mounting bracket bottom plate is more than 10 times of sensor diameters, it is ensured that when the blast wave that blast is formed passes through panel
Form stable plane wave.
Described sensor is installed wraps up in plastic tube outside core, by being interference fitted in the mounting hole fixed to mounting bracket bottom plate,
Outer wrap up in when plastic tube is used for sensor test is insulated with external environment.
The sensitive area of the sensor is concordant with mounting bracket backplate surface.
The beneficial effects of the invention are as follows：Realize the comprehensive survey of same point position explosion wave press method and electrical measuring method
Examination, can obtain mechanically deform amount and the relation of shock wave overpressure, so as to realize two kinds by data analysis after test of many times
The regression nature of test.
