脉冲载荷作用下结构响应灵敏度分析

以结构固有频率、振型灵敏度分析结果为基础，解决了在脉冲载荷作用下结构响应灵敏度的理论分析和数值计算。为火炮、弹箭等一系列受有冲击载荷作用的结构动力优化设计和修改提供了更为科学的依据。

Dynamic Response Sensitivity Analysis of the Structures Subjected to Implusive Loads

The theo retical analysis a nd the numerical calc ulatio n o f dyiia inic respo nse sensitivity ofthe stucture subjected to implusive loads are done on the basis of the iesults of natuial frequ-ency and mode shape sensitivity in this paper.The generated methods are the scientific foun-dations of dynamic optimazation and modification for a series of the structures applied inthe forms of impact loads as artillery projectile and rocket and so on.
