摘　　要：考虑系统横向振动和扭转振动的耦合作用,采用集中参数法建立施密特平行轴联轴器系统动力学分析模型,根据牛顿力学定律,推导出传动系统的动力学方程。考虑发动机激励和误差激励的作用,采用Gill数值积分法对传动系统的动态响应进行研究,得出系统动态性能良好,其振动属于准周期性运动等结论,为进一步的动态性能优化和工程应用提供理论指导。Considering the coupling interaction between transverse vibration and torsional vibration of the system,a dynamic analysis model of the Schmidt offset coupling is established by the method of concentrated parameter and the dynamic equation of this system is deduced by the Newton method.Considering the effect of engine and error excitations on the transmission system,the Gill numerical solution method is used to study the dynamic response of the drive system.The results show that it has a good dynamic performance and its vibration belongs to almost periodic vibration,which provides theoretical guidance for further dynamic performance optimization and engineering application.
