摘　　要：从冲击谱分析的基本原理入手,将冲击谱分析算法的理论和实现途径做出比较分析后采用基于C语言实现了改进的递归数字滤波算法,通过试验验证了算法的正确性,为工程实践中的冲击谱分析提供了一种通用性相对较好的分析手段。Starting from the basic theory of shock response spectrum, the arithmetic theory and realiza- tion approach were analyzed. The improved recursive digital filter put forwarded algorithm was based on C language. The correctness of arithmetic was validated by testing. The purpose was to provide better analysis methods for engineering practice.
