摘要
智轨列车以电力驱动,使用液压系统实现转向功能,如果能采用电力驱动的电动缸实现转向功能,将减小转向系统安装空间,并能避免能量在转换过程中的损失,达到节能减排的目的。目前伺服电机不断提高的功重比也为实现这一目标创造了条件。文章建立智轨列车电动缸转向系统的数学模型;使用MATLAB/Simulink软件建立电动缸转向系统的仿真模型,对电动缸转向系统的动态性能进行仿真;根据智轨列车实际工况搭建了电动缸转向系统动态性能测试试验台,对电动缸转向系统的动态性能进行测试,并将仿真数据和试验数据进行对比。对比分析表明,仿真结果与试验结果具有很好的一致性,证明所建数学模型准确性,同时也验证了电动缸转向系统替代液压缸转向系统的可行性。
The autonomous rail rapid transit(ART) is powered by electric power but uses a hydraulic system to achieve steering function. If the electric drive electric cylinder can be used to realize the steering function, it will effectively save the installation space of the steering system, and can avoid the loss of energy in the conversion process, and achieve the purpose of energy saving and emission reduction. The continuously improving power weight ratio of the modern servo motor also created conditions for achieving this goal. In this paper, the mathematical model of the electric cylinder steering system of the ART was established firstly, and then the simulation model of the electric cylinder steering system in MATLAB/Simulink was established to simulate the dynamic performance of the electric cylinder steering system. Thereafter, according to the actual working conditions of the ART, the dynamic performance test bench of the electric cylinder steering system was built and used to test the dynamic performance of the electric cylinder steering system. Finally, the simulation data and the test data were compared. The comparative analysis showed that the simulation results were in good agreement with the test results, which proved that the mathematical model was accurate and also verified the feasibility of replacing the hydraulic cylinder steering system with the electric cylinder steering system.
