摘要

打磨车在工作过程中，打磨电机靠偏转油缸来调整电机的打磨角度，工作时会出现偏转油缸剧烈振动的情况。为了研究此振动特性，通过分析打磨电机偏转液压系统的工作原理，建立了偏转油缸的受力数学模型，并用AMESim 液压仿真软件进行仿真。仿真结果表明：液压锁存在时，摇架内偏转角度在20°范围内，液压缸运行速度稳定；当偏转角度大于20°后，摇架开始振动，随着偏转角度继续增加，振幅变大，振动频率加快。为了解决此振动对打磨的影响，提出了增加节流阀或增加溢流阀的办法。

Abstract

When grinding car is in the process of work, the grinding motor adjusts its grinding angle by deflection hydraulic cylinder, and severe vibration will appear when the cylinder is working. In order to study the vibration characteristics, firstly, the working principle of the hydraulic system of the grinding motor was analyzed, then the mathematical model of the force of the hydraulic system was established and the AMESim hydraulic simulation software was used for simulation. Results showed that, when there was hydraulic-lock, the hydraulic cylinder speed was stably when the cradle deflection angle was within 20 degrees; when the deflection angle was greater than 20 degrees, the cradle started vibrate, the amplitude and frequency was greater with the increase of deflection angle. In order to solve this problem, a method for adding throttle valve or overflow valve was proposed.
