摘　　要：针对轴系在不同激励条件下的动力响应问题,基于Newmark-β法,运用MATLAB软件编程,实现对鱼雷推进轴系的动力响应分析,通过与ANSYS软件计算结果的对比,验证所建模型和MATLAB计算程序的合理性;同时得出推进轴系的动力响应与激励条件的线性变化关系。In order to study dynamic response of the shafting based on multiple-excitation,the MATLAB program is used to achieve the response analysis of torpedo propulsion shafting on the basis of Newmark-β method.By comparing the results with that of ANSYS,the reasonableness of the model and the MATLAB program is verified.The linear relationship between analysis of dynamic response and input conditions is also given.
