| 摘要 |
<p>The invention concerns a pyrotechnical test stand for producing acceleration and deceleration with simple or complex spectra, characterised in that the test bench consists of a launch tube (2) or a mobile equipment damper (6), whereof the internal pressure levels are generated and modulated by the programmed ignition of pyrotechnical gas generators (15) and by the opening of gas-ejecting vents (18) with adjustable surfaces and positions and programmed apertures. The characteristics of the gas generators and vents are pre-computed by means of simulation software to obtain the required acceleration and deceleration law.</p> |
