摘要
电动汽车作为一种绿色无污染的交通工具,具有广阔的发展前景。电动汽车需要具有较好的振动特性、良好的操纵稳定性和乘坐舒适性,这给驱动系统的设计提出了较高要求。以某款电动汽车驱动系统为研究对象,建立了其动力学模型。利用Matlab软件中的Simulink模块建立了电动汽车驱动系统仿真模型。设置仿真模型参数,并对电动汽车驱动系统在一、二挡不同工况下的扭转振动响应特性进行分析。电动汽车在制动工况下的扭转振动响应更明显。分析结果为电动汽车驱动系统结构参数的确定提供了边界条件和决策依据。
As a green and pollution-free means of transportation,electric vehicles have broad prospects for development.Electric vehicles need to have better vibration characteristics,good handling stability and ride comfort,which puts forward higher requirements for the design of drive system.Taking an electric vehicle drive system as the research object,a dynamic model is established.The simulation model of electric vehicle drive system is established by using Simulink module in Matlab software.The parameters of the simulation model are set,and the torsional vibration response characteristics of the electric vehicle drive system under different working conditions of the first and second gears are analyzed.The torsional vibration response of electric vehicle under braking condition is more obvious.The analysis results provide the boundary conditions and decision basis for determining the structural parameters of electric vehicle drive system.
