统计能量分析法在爆炸分离冲击响应预示中的应用

Application of statistical energy analysis method in prediction of pyroshock responses

  • 摘要: 针对复杂结构的爆炸分离冲击问题,文章采用统计能量分析方法对其响应进行了计算分析。首先对切割索产生的连续载荷进行了离散处理,然后基于统计能量分析并结合虚拟模态综合法,对航天器分离过程中的冲击响应进行了预示。得到的结果符合爆炸分离冲击环境下结构响应特征及其传递规律,对航天器抗冲击设计与评估具有一定的参考价值。

     

    Abstract: In this paper, a statistical energy analysis of pyroshock responses is carried out for complex structures. Firstly, the continuous impact load imposed by the dragline is discretized. Then a statistical energy analysis combined with a virtual mode synthesis is performed to predict the pyroshock responses in a typical spacecraft structure. The results agree with the general trends of the responses and their transfers at related conditions.
