摘要
针对某火工分离作动器分离作用时冲击过大的问题,基于装置结构及工作原理进行冲击特征点分析,在仿真计算设计参数对冲击影响程度的基础上,提出了优化装药设计和设置异型金属缓冲结构相结合的冲击抑制技术。仿真分析及试验验证表明,提出的冲击抑制技术有效,可将该分离作动器的冲击峰值由3 645.30g降至635.55g。本研究为火工装置类产品的降冲击设计提供了参考。
Aimed at the problem that high impact generated by the action of some separation actuator,based on its fundamental structure and working principle,the major shock sources of the device were analyzed.On the basis of simulation calculation of impact degree by design parameters,the suppression technology of charge optimization combined setting the aluminum buffering ring were proposed.The simulation analysis and separation test show the suppression technology is effective,the peak of impact is reduced from 3645.30g to 635.55g.The study provides a guidance for impact reduction design of explosive separation devices.
