摘要
在当前的车辆开发中,转向力的目标主要靠后期实车调校来实现,究其原因是仿真模型对转向力矩的表达不够准确。本文介绍了转向系统摩擦特性的测试方法,并采用Lugre摩擦模型进行参数辨识,利用Simulink搭建转向系统及摩擦模型,通过仿真与试验对比,验证了转向系统对于力矩表达的精确性,为未来虚拟标定、虚拟调校等提供支撑。
In the current vehicle development,the goal of steering force is mainly achieved by the later actual vehicle tuning,because the simulation model does not express the steering torque accurately.This paper introduces the test method of friction characteristics of the steering system,uses the Lugre friction model for parameter identification,uses Simulink to build the steering system and friction model,and verifies the accuracy of the torque expression of the steering system through simulation and test comparison,so as to provide support for future virtual calibration and virtual adjustment.
