摘要
针对轻型汽车采用轮毂电机后簧下质量明显增加的特点,基于MatlaB/SIMULINK建立七自由度整车模型并进行随机输入与脉冲输入仿真,分析轻型汽车采用轮毂电机对平顺性的影响,以车身加速度均方根值、车轮相对动载荷均方根值和车身最大加速度为优化目标对悬架系统参数进行了匹配优化,结果表明采用轮毂电机的轻型汽车在簧下质量增加一倍的情况下,应减小车身固有频率参数值至1.03左右,增加悬架阻尼比至0.35左右,减小刚度比至10左右,优化后随机输入下70kim/h时的车身加速度均方根值和车轮动载荷均方根值在比优化前分别改善22.2%和25.8%,脉冲输入下20km/h时的车身最大加速度比优化前改善24.4%。
For the characteristics of light vehicles that the unsprung mass increases significantly when using hub motors,the seven DOF full vehicle model was established based on Matlab/SIMULINK to carry out simulation on random input and pulse input.The impact of hub motors on ride comfort of light vehicle was analyzed.The match optimization of suspension system parameters was carried out with the optimization targets as rms of body acceleration,rms of wheel' s relative dynamic load and maximum acceleration of body.The results showed that in the case that unsprung mass of light vehicles doubled when using hub motors,the natural frequency of the body should be reduced to around 1.03,the damping ratio of suspension should be increased to around 0.35,and the stiffness ratio should be reduced to around 10.After optimization,rms of body acceleration and rms of wheel' s relative dynamic load improved by 22.2% and 25.8%respectively on random input at 70km/h,the maximum acceleration of body improved by 24.4% on pulse input at 20km/h.
