摘要
为降低电动轮对车辆垂向振动性能的负面效应,提高车辆行驶平顺性和安全性,将轮毂电机视为动力减振器,设计了车身减振型、车轮减振型和综合减振型等不同减振方案,采用粒子群优化算法对各方案中减振系统的弹簧刚度、阻尼进行优化,并利用随机路面和脉冲路面激励验证不同方案的减振效果。结果表明,经过参数优化的几种减振方案均可有效减小车轮和整车的垂向振动,优化车辆行驶平顺性,其中,轮毂电机同时与车身、车轴相连的综合减振型方案减振效果最佳。
In order to reduce the negative effect of electric wheel on vehicle vertical vibration performance and improve vehicle ride comfort and safety,different designs are proposed with the hub motor as power vibration absorber,including body vibration reduction design,wheel vibration reduction design and combined design.Particle Swarm Optimization(PSO)is used to optimize the spring stiffness and damping in above designs and their vibration reduction effects are verified by random and impulse road surface excitation tests.The results show that above designs with optimized parameters can effectively reduce the vertical vibration of wheels and vehicles,improve vehicle ride comfort.Among them,the combined design displays best effects with hub motors connected to the body and axle.
