摘要
研究车速对汽车转向力矩的影响对电动转向系统中助力特性曲线的确定十分重要。在对转向力矩形成机理进行分析的基础上,根据汽车操纵动力学、转向系统动力学模型和轮胎半经验模型,建立了转向力矩的分析模型。通过仿真分析了车速、载荷转移及切向力等因素对转向力矩的影响,得到了一些有用的结论。
Since the speed of vehicle has great effects on steering torque, it is very important to determinate assisting curve of Electric Power Steering. After analysis of the formation principles of steering torque and incorporation of vehicle handling dynamics, steering system's dynamics and experimental tire model, an analytical model of steering torque was built, The effects of speed, load transfer and tangent force on steering torque were analyzed based on simulation of the steering model, and several useful conclusions were drawn.
