为分析核动力设备阀架的抗冲击强度并验证ASMEⅢ规范用于抗冲击强度校核的可行性，以柴油发电机组的阀架抗冲击强度校核为例，采用ABAQUS软件进行抗冲击时程计算，对阀架的应力响应采用ASMEⅢNF的力学评定要求进行校核，并根据GJB 1060．1－91对校核结构进行对比验证。结果表明：两种校核工况下，阀架的抗冲击强度满足要求，且按ASMEⅢ计算的冲击失效系数更小，能够充分发挥材料和结构的性能，提高抗冲击设计的经济性。

To analysis shock resistance strength of nuclear equipment mounting and verify the feasibility of ASME Ⅲ to shock resistance strength evaluation, ABAQUS is used to make shock resistance time domain calculation by taking the diesel gen-erator set's mounting as an example.Evaluate stress intensity of the mounting with ASMEⅢNF, and then verify the result with GJB 1060.1-91.The numerical results show that the mounting's shock resistance strength is safe for two evaluation cases; the shock failure factor calculated by ASMEⅢis smaller;the performance of material and structure can be improved by ASMEⅢso as the economy of shock resistance design.
