Simulation of Steering Wheel Reaction Torque under All Operating Condition by A Torque Motor

在汽车动态模拟系统中，转向盘反力矩的仿真逼真度影响实验驾驶员的操纵行为，从而影响驾驶模拟实验的准确性。本文系统地阐述了利用力矩电机进行全工况仿真汽车转向盘反力矩的原理、力矩电机的工况分析及稳态误差分析等，为全工况仿真汽车转向盘反力矩提供了一种新方法。

In a dynamic simulation system for motor vehicle,the fidelity of simulated steering wheel reaction torque has influence on the operating behaviour of experimented drivers,so that has also influence on the accuracy of simulation of drivers' operation. This paper systematically describes the simulation of steering wheel reaction torque under all operating conditions by utilizing a torque motor,its principle,condition analysis and steady - state error analysis of torque motor. It provided a new approach for simulating of steering wheel reaction torque under all operating conditions.
