摘　　要：为了获取潜艇内多杆机构在运动过程中动力学特性,增强在方案设计评估和问题处理过程中的把控能力,本文利用Ls-Dyna显式求解器从模型离散、求解参数设置等方面对多杆机构有限元模型进行了优化设计,得到了计算结果与试验数据吻合性较好的仿真评估模型,为技术人员开展具体方案设计、故障问题分析等提供了有益参考。In order to obtain the dynamic characteristics of the multi-bar mechanism in the submarine in the process of motion and enhance the control ability in the process of scheme design evaluation and problem solving,Ls-Dyna explicit solver is used to optimize the finite element model of multi-bar mechanism from the model discretization and solution parameter setting.Then,the simulation evaluation model with good agreement between the calculation results and test data is obtained,which provided useful reference for technical personnel to carry out specific scheme design and fault analysis.
