摘要
冲击响应谱作为试验规范已被用于冲击环境试验。制订一个能真实模拟实际冲击环境的冲击响应谱是冲击环境试验的前提,文中对冲击实测时域数据的预处理,冲击持续时间的确定,冲击响应谱的计算,冲击响应谱的归纳方法进行了研究,并用实测的冲击数据,归纳出某型号冲击试验的冲击响应谱。
The shock response spectrum was applied in shock environmental test as a standard. It is very important to make a reasonable shock test spectrum that can insure the test artiele to be exlyerienced on certain desired shock enviromnent. The method of shock data validation, editing, and analysis were put tbrward. The statistical procedures of shock response spectrum for estimation were also studied. The shock response speetrum of shock environment in ignition shock section of rocket engine was predicted from its time histories.
