基于非对称缸的液压齿轮齿条转向器模拟测试实验台设计与研究

摘要

In view of the gear rack steering gear test system as the object, the asymmetric cylinder hydraulic steering gear and rack AMESim simulation model test system is established,and the symmetrical valve controlled asymmetrical cylinder speed character-istic is analyzed.Based on Simulink/XPC Target module environment,real time online monitoring and control system was developed. The asymmetric cylinder of the hydraulic steering gear and rack simulation testing experiment was set up.The experimental results show that the physical simulation results and the AMESim simulation results have good consistency.%针对齿轮齿条转向器测试系统为对象,建立非对称缸的液压齿轮齿条转向器测试系统AMESim仿真模型,分析对称阀控非对称缸的速度特性.开发了基于Simulink/XPC Target模块环境下的实时在线监测控制系统.搭建了非对称缸的液压齿轮齿条转向器模拟测试实验台,实验结果证明,实物仿真结果和AMESim仿真结果有较好的一致性.
