摘要
分析了单自由度弹簧－质体体系对爆炸冲击载荷的特征响应，建立起结构体对爆炸冲击载荷响应的数值模型，并从此模型出发，对爆炸冲击波破坏准则Ｐ－Ｉ准则进行合理性分析，确定其可靠性．
This paper analyses the special response of single degree of freedom spring matter system to explosive shock loading,and set up a numerical model of explosive shock loading response on structures.Based on the model,the reasonableness of explosive shock wave destructive criterion(P I criterion) is analysed,and the criterion reliable information is defined.
