Design and realization of railway vehicle dynamics hardware-in-the-loop simulation system

由于铁路车辆轮轨关系具有复杂性、强耦合性以及实际工况不可复现性的特点,轮轨黏着控制算法存在难以验证的问题。通过对铁路车辆在轨道上运行工况及受力情况进行分析,构建了动力学半实物仿真系统,以模拟铁路车辆轮对的动力学特性,利用牵引控制单元对动力学半实物仿真系统进行了测试,结果证明了动力学半实物仿真系统能够为轮轨黏着控制算法的验证提供技术支持,具备通用性和可移植性。

Due to the complexity,strong couplingand non reproducibility of actual working conditions in the wheel-rail relationship of railway vehicles,the wheel-rail adhesion control algorithm is difficult to verify.By analyzing the operating conditions and force conditions of railway vehicles on the track,a dynamic hardware-inthe-loop simulation system was built to simulate the dynamic characteristics of railway vehicle wheelsets.The dynamic hardware-in-the-loop simulation system was tested by using a traction control unit,and the results showed that the dynamic hardware-in-the-loop simulation system can provide technical support for the verification of wheel-rail adhesion control algorithms,and has universality and portability.
