摘要
研究多自由度系统冲击激励与响应之间的关系，应用模态分析理论和概率统计理论，提出了多自由度系统ＳＲＳＳ冲击谱计算方法，并将该方法成功地应用到工程实例中。
This paper deals with the relationship between shock excitation and response.With modal analyses and probability theories,we advanced a new method for the multi- degrees-of -freedom system,called SRSS shock spectrum method.Using this new method we have successfully solved a series of shock problems in engineering.
