摘要： 为研究商用车转向盘阻力矩,在商用车转向动力学分析中引入了LuGre模型,建立了轮胎回正力矩和转向摩擦阻力矩模型以及转向盘阻力矩模型。借助该模型对CA1045轻型货车转向盘操纵阻力矩与转向角、车速的关系进行了分析,仿真与实车试验结果对比表明,仿真与试验得到的转向阻力矩差异在5 N·m以内。

Abstract: To study the resistance torque of the steering wheel of a commercial vehicle, the LuGre model is introduced into the steering dynamics analysis of a commercial vehicle, and the model for aligning torque and steering friction resistance torque of tire and the resistance torque model of steering wheel are established. With these models the relationship among steering resistance torque, steering angle and vehicle speed of a CA1045 light truck is analyzed. The comparison between the results of simulation and real vehicle test shows that their difference in steering resistance torque is less than 5 N·m.
