| 摘 要： | 摆锤式冲击响应谱试验台是模拟爆炸冲击环境的一种较好手段,它能够模拟拐点频率在300Hz～2000Hz,峰值过载高达几千个g值的冲击谱型。根据该装置的结构和基本原理,本文应用有限元分析软件ANSYS,LS-DYNA等对其冲击响应谱产生过程进行了模拟,计算结果与试验数据吻合较好。此方法能够合理有效地模拟该装置的性能曲线,对摆锤式冲击试验台的设计具有指导意义。

| Abstract: | The pendulum shock response spectra testing equipments play great part in simulating pyroshock environment, which can simulate high g shock wave and the cross frequency ranging from 300Hz to 2000Hz. According to the structure and basic rules, the shock response spectra wave has been simulated with finite method software ANSYS and LS-DYNA. The result reveals a good correlation with the empirical data. This method can simulate the structure＇s characteristic wave in a more precise way, which can be a good guide for the design of the pendulum shock testing machine. |
