利用SIMPACK软件建立了车架电机机车的完整动力学模型，分析了传动装置悬架纵向和横向刚度对其加速度和车辆平顺性的影响。结果表明，在10kN.m-1处选取悬架刚度的数值，可以显著改善机车的横向平稳性和电机的工作条件。摆式悬挂是实现弹性悬挂的重要手段，提出了等效刚度的概念，在相同等效刚度的情况下，柔性模型的计算结果与传统模型的计算结果吻合较好。
A complete dynamics model of locomotive with motor mounted on frame is established by means of SIMPACK.The influence of the driving equipment suspension longitudinal and lateral stiffness on its accelerations and car riding quality is analyzed.It is found that by selecting the numerical value of suspension stiffness at 10 kn·m~(-1),the lateral riding quality and motor work conditions can be improved noticeably,the lateral wheel/rail interaction forces can be deceased effectively.The stability can also be increased obviously.Pendulum suspension is an important measure to realize elastic suspension.The concept of equivalent stiffness is put forward.Under the same equivalent stiffness the results of the flexible model agree well with that of traditional model.
