摘　　要：以转向试验台架为研究对象,使用UG软件建立了转向试验台架的三维模型。将该三维模型导入ADMAS建立了电动助力转向系统的多体动力学模型。使用SIMULINK软件建立助力电机模型,选择直线型助力特性曲线为电动助力转向系统的助力特性曲线,搭建了电动助力转向系统的PID控制系统,整定了PID参数。进行了电动助力转向系统的联合仿真,实验结果符合相关要求,表明电动助力转向系统虚拟试验平台搭建成功。Steering test bench is studied in this paper, and a three-dimensional model test bench is established by UG software. The three-dimensional model is introduced into ADAMS software, and e- lectric power steering system of multi-body dynamics model is established. Booster motor model is es- tablished by SIMULINK software, linear assist characteristic curve is selected as the electric power steering system booster characteristic curve, the electric power steering system PID control system is set up, and PID parameters are tuned. Co-simulation of electric power steering system has been carried out, and the results meet the relevant requirements. The co-simulation results show that the electric power steering system virtual experiment platform has been built successfully.
