Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific examples.

[0022] Take a certain type of missile as an example below to illustrate embodiments of the present invention. The structure diagram of the present invention is as figure 1 ; Structure block diagram such as figure 2 .

[0023] The testing machine in this example is used for the dynamic blasting performance test of the fragile front cover of a certain type of missile storage and transportation launcher. When the testing machine enters the inflated state, the electromagnetic pneumatic reversing valve I (normally closed type) is opened due to energization, the electromagnetic pneumatic reversing valve II (normally open type) is kept open due to no energization, and the intake pipe is completely connected. Depend on figure 1 It can be seen that the compressed air enters the cylinder through the air inlet and outlet A, pushes the piston to the right and presses the nozzle B tig...

Abstract

The invention relates to an air impact testing machine for detecting a fragile / fissile cover of a missile storage / transportation launcher. The testing machine comprises a cannon head, an air tank, a testing cylinder, an electromagnetic pneumatic reversing valve and a central control system. The cannon head is transversely arranged in the middle of the air tank; the back end of the cannon head is connected with the front end of the testing cylinder; the back end of the testing cylinder is used for arranging the fragile / fissile cover of the missile storage / transportation launcher for testing; the electromagnetic pneumatic reversing valve is arranged at the front end of the cannon head; and the central control system is connected with a control coil of the electromagnetic pneumatic reversing valve. The invention has the advantages that the pressure distribution on the inner wall of the fragile / fissile cover from the high-speed flowing compressed air during the test is guaranteed to be completely equal to the action force distribution on the inner wall of the fragile / fissile cover from the fuel under the actual use condition, and the stress state of the specimen under the analogue test condition guaranteed to be consistent to the actual use condition; and the air impact testing machine uses the compressed air as power and has the advantages of simple operation, low labor and low cost. The air impact testing machine is suitable to tests in large quantities.

Description

technical field [0001] The invention relates to a detection device for the dynamic blasting performance of a fragile / cracked sealing cover at the end of a missile storage and transportation launch tube, in particular to a gas impact test machine for detecting the fragile / crack cover of the missile storage and transportation launch tube. Background technique [0002] The storage launch tube is a device used to store missiles. It forms a closed container together with the front and rear end covers, and becomes a barrier to protect the missiles in the barrel from damage and interference from external factors such as high temperature, low temperature, moisture, corrosive medium, electric field, and magnetic field. The frangible / crack cover not only has the above-mentioned protective function, but also because it is guarded at the mouth of the storage and transportation launcher, it is a necessary place for the missile to fly out. Therefore, before the missile is released from t...
