一种气动式冲击响应谱试验系统的研制

Development of a pneumatic test system for shock response spectrum simulation

  • 摘要: 传统的摆锤式冲击台冲击能量小,可匹配的试验负载和可实现的试验量级都偏小,不能满足当前大型航天器高量级冲击试验需求,因此研制了一套能够进行大质量产品高量级冲击响应谱模拟试验的系统。文章给出该系统的设计原理和设计方法,包括采用双冲击气缸和双储气缸,以及冲击锤体自适应技术和台面复位技术。经测试,该气动式冲击响应谱试验系统各项技术指标均达到设计要求。

     

    Abstract: The impact energy of the traditional pendulum impact test equipment is too small to generate a high magnitude impact for large products. In this paper, a pneumatic impact test system is designed, which can produce a high-magnitude shock response spectrum for the impact test of the high-mass spacecraft. The principle and the method for designing the system are presented, including the double impact cylinders and the double storage cylinders, as well as the impact hammer adaptive technology and the table reset technology. The test results show that the technical specifications of the system can meet the design requirements.
