摘　　要：通过ADAMS VIEW软件建立模型,采用将弹性车轮引入轮毂电机系统的使用,通过编写接触算法解决动态接触时的高频振动问题,并通过参数优化选择,来达到如何能最大程度并且合理的降低轮芯处轮毂电机系统所受到的振动冲击目的。研究结果表明,弹性车轮的引入能够很大程度上减少通过轨缝时对轮毂电机产生的冲击,在对刚度参数进行合理的选择分析后,最高减小了78.5%的正向冲击加速度以及56.1%的负向冲击加速度。能够有效的达到减小轮毂电机冲击,降低了电机在机械方面安全性隐患的目的。A model of resilient wheel with in-wheel motor was establishes by using the dynamics program ADAMS View.A contact algorithm was built to deal with the high frequency vibration issue during dynamic contact.Then the stiffness parameters were optimized in order to reduce the vibration impact reasonably and maximally.The results show that the adoption of resilient wheel can greatly reduce the impact to motor during crossing the gap.And after the stiffness parameters were optimized,the positive impact can reduce by78.5percent and the negative impact can reduce by 56.1percent at most.The adoption and optimized method can successfully reduce the motor impact and improve the security and stability.
