Detailed Description
As shown in fig. 1-3, a pneumatic simulated shooting platform, includes pneumatics rack 1 and the high-pressure gas cylinder 2 of storing compressed air, the pneumatics rack is through first pipeline 3 and high-pressure cylinder intercommunication, first pipeline is provided with check valve 4, high-pressure cylinder supplies magazine 6 intercommunication through second pipeline 5 and the warhead of placing the warhead, the second pipeline is provided with control second pipeline and switches on or closed solenoid valve 7, and the export that the warhead supplied the magazine is provided with the bore pipe 8 that is used for the warhead to jet out with higher speed. The pneumatic simulated shooting platform compresses air through the matching of the air compressor cabinet and the check valve, stores the air in the high-pressure air bottle and the second pipeline from the electromagnetic valve to the high-pressure air bottle, can control the pressure intensity in the high-pressure air bottle, enables the high-pressure air bottle to have enough pressure intensity to release the compressed air instantly, and further enables the warhead to have enough initial velocity of instant firing; after the high-pressure gas cylinder releases the compressed air, the pressure inside the high-pressure gas cylinder keeps balance with the outside, the condition of continuous bullet cannot occur, and the operation safety is improved; the second pipeline is conducted or closed through the electromagnetic valve, compressed air is released instantly to enter the bullet supply bin, the bullet placed in the bullet supply bin is pushed to accelerate and eject in the bore tube, and bullet shooting is simulated to detect bulletproof equipment under the condition that firearms and ammunition do not need to be held; meanwhile, the speed of the bullet can be adjusted according to the pressure of compressed air or the length of the bore tube, the speed of bullets of various gun types can be simulated, the application range is wide, and the testing and research and development cost of the bulletproof equipment is reduced.
The pressure value of the compressed gas of the high-pressure gas bottle is PGas cylinder(ii) a The cross section area of the inner cavity of the hearth tube is SBore tubeThe gas thrust is F, the length of the bore tube is LBore tubeWarhead weight is M and warhead speed is VSpring speedGas volume of high-pressure gas cylinder, gas volume of bore tube, solenoid valve toThe gas volumes of the pipelines of the high-pressure gas cylinder are respectively VGas cylinder；VBore tube；VPipeline from electromagnetic valve to gas cylinder. Thrust by gas: f = P × S; the gas does work: w = F × L; kinetic energy of warhead: ek = 1/2M VSpring speed 2(ii) a Energy conversion: w = Ek available:
bullet discharging speed: vSpring speed= 
The friction force of the bullet in the bore tube and the influence of the heat generated by the friction bore tube on the air pressure are also caused; the influence of gas temperature reduction on the gas pressure caused by heat absorption when the compressed gas expands rapidly; the gas can not do work evenly in the process of expanding to push the warhead to move, and the acceleration is reduced gradually.
Under the condition that the requirements of the cross section area of the inner cavity of the bore tube, the cross section area S of the bullet, the weight M of the bullet and the bore discharge speed V are determined, the influence of the factors on the bore discharge speed V is met by adjusting the gas pressure P and the length of the bore tube L.
The pressure intensity adopts the arithmetic mean value of the initial air pressure value of the air bottle and the pressure intensity before the bullet is taken out of the chamber:
pwave =1/2 [ P ]Gas cylinder+PGas cylinder*VGas cylinder/（VGas cylinder+VBore tube+VPipeline from electromagnetic valve to gas cylinder）】
And (3) correcting the discharge speed of the bullet:
the discharging speed: vSpring speed=
The first conduit is in communication with a second conduit. The opening of the high-pressure gas cylinder can be reduced, and the risk of leakage of compressed air from the opening is reduced.
The second pipeline is further provided with an air pressure sensor 9 and an air pressure meter 10, and the air pressure sensor is further in communication connection with the air compressor cabinet.
