| 摘 要： | 运用实车试验得到了汽车转向系统的助力特性曲线图和汽车在非转向情况下助力电机的怠速功率。在AMEsim的平台上建立了电控液压助力转向系统(EHPS),根据所建立的模型进行仿真。结果表明:车辆在转向情况下,转向阀的功率损失是最大的;在非转向情况下,转向电机的怠速功率损失是主要的。最后通过改变转向阀的主要结构参数,说明其对功率损失的影响。

| Abstract: | Through the real vehicle test,the characteristic curve of the steering system and the idling power of the power steering motor in condition of non-steering are achieved.The electrical hydraulic power steering system is established on the platform of AMEsim.Simulation is carried out on the basis of the proposed model,and the simulation results indicate that the loss of steering valve power is the largest in case of the vehicle steering;in the case of vehicle non-steering,the loss of the idling power of the power steering motor is the main loss.Finally,through the change of the main structural parameters of the steering valve,it shows the effect of power loss. |
