Problems solved by technology

[0004] At present, most of the test devices for generating shock waves basically use bursting discs to explode to generate shock waves, but the broken diaphragm of this type of shock wave instantaneous pressure relief device will interfere with the experimental flow field, and the bursting discs need to be replaced frequently, resulting in low experimental efficiency. Moreover, this type of experimental device cannot adjust the action time of the shock wave, and it is also very inconvenient to control the shock wave pressure.

The labor hour of a single laboratory is saved by more than 4000 hours per year, and the cost of more than 0.2 billion RMB can be saved for the same type of laboratories in the whole society every year.

Description

Technical field [0001] The present invention relates to the technical field of shock wave test equipment, and more particularly to a test device for controllable shock waves. Background technique [0002] In an occasion of instant release of high and low pressure, there is a shock wave, such as explosion and explosion, there is a shock wave of different pressures. The device currently generating shock waves is a TNT explosive explosion, explosive hoses or high pressure hosted drain discharges. [0003] The shock wave is an important physical phenomenon in the airflow. The impact wave pipe is an experimental device that generates a shock wave, and a shock wave is generated by utilizing a high and low segment. The key to the impact wave pipe design is that the instant relief apparatus has a substantial requirement of its design, and the gas emission flow is large, and the operation is convenient. In the same case of other conditions, the quick slowness of the unforced pressure dire...
