摘要 现有高铁轨道动力测试系统激振装置采用的阀控缸或泵控马达液压激振方式,很难同时满足高振动频率、高激振力和高振幅的要求。针对这些问题,提出一种双环面液压缸,并设计了相应的电液伺服激振系统。根据试验系统参数,建立液压系统的数学模型。运用MATLAB/Simulink对系统进行理论分析和数字仿真,利用PID Tuner工具调整PID控制器参数。结果表明,所设计的液压激振系统满足设计要求。 The existing hydraulic excitation mode of valve controlled cylinder or pump controlled motor used in the excitation device of high-speed rail track dynamic test system, is difficult to meet the high vibration frequency, high excitation force and high amplitude requirements. Aiming at these problems, a bicyclic side hydraulic cylinder was put forward, and the corresponding electro-hydraulic servo excitation system was designed. According to the test system parameters, the mathematical model of the hydraulic system was established. MATLAB/Simulink was used to make theoretical analysis and digital simulation. The tool of PID Tuner was used to adjust the PID controller parameters. The results show that the designed hydraulic excitation system meets the design requirements.
