摘要
本文以轮毂电动汽车为依托,建立了1/4车辆双质量振动系统模型,根据系统振动方程,建立MATLAB/Simulink仿真模型,并以此分别分析在路面脉冲激励和路面随机激励下,以不同车速行驶时非簧载质量的增加对车身部分加速度的影响。通过建立传递函数分析不同非簧载质量情况下,车身加速度、相对动载荷和悬架动挠度对路面速度激励的响应情况。最后对目前针对非簧载质量增加对于整车平顺性不利影响的解决方案进行了对比分析。
In this paper,based on wheel hub electric cars,1/4 vehicle vibration system of double quality model is established, Based on the system vibration equation of MATLAB/Simulink simulation model is set up,and thus analyze on the road and pavement random excitation pulse excitation to increase the unsprung mass of the vehicle with different effects on the body part acceleration. Through the establishment of the transfer function analysis different circumstances of unsprung mass,body acceleration,relative dynamic load and suspension dynamic deflection of pavement response speed incentives. Finally,the current for the unsprung mass increases the bad influence for the vehicle ride comfort solutions are analyzed.
