摘　　要：主要分析动态设计方法(DDAM)进行船舶推进轴系抗冲击计算的不足,研究时域方法的可行性;并应用时域方法进行部分轴段和轴瓦的冲击响应计算,冲击激励采用BV0430标准;通过计算得到了Von Mises应力和位移响应,找到冲击薄弱部位和部件,给出冲击激励施加方法及其依据,为抗冲优化设计提供参考。The deficiency of the dynamic design method（DDAM） that is adopted to calculate the antishock capability of propulsion shaft is analyzed and the feasibility of time-domain means is studied. The shock response calculations of the part of the shaft and sleeve are carried out by time domain methods that impact incentives is introduced by BV0430 standards. According to the results of calculation,the Von Mises stress and displacement response were obtained, the weak parts of impact were found, the applied method and basis of impact incentives were presented in order to provide the reference on the optimal design of anti- shock.
