【摘要】：对某型号磨机换衬板机械手,在原有液压系统基础上,提出了采用位置反馈控制、电液比例控制变量泵相结合的系统改造方案,以解决原系统存在启、停冲击大,操控不灵活的问题,并且可以减少原有系统的功率损失。对方案中液压缸位置反馈控制和电液比例控制变量泵的设计,应用AMESim软件建立了完整的仿真模型,通过对仿真结果的分析,得出了液压缸位置反馈控制的响应精度、变量泵在电液比例控制下的动态输出特性。仿真结果表明改造后的磨机换衬板液压系统与原系统相比控制精度更高、响应速度更快,系统效率更高。
[Abstract]:On the basis of the original hydraulic system, this paper puts forward a system retrofit scheme which combines position feedback control and electro-hydraulic proportional control variable pump to solve the problem that the original system has a starting and stopping impact. For the design of hydraulic cylinder position feedback control and electro-hydraulic proportional control variable pump, a complete simulation model is established by using AMESim software. Through the analysis of the simulation results, the response accuracy of the hydraulic cylinder position feedback control is obtained. The dynamic output characteristics of variable pump under electro-hydraulic proportional control. The simulation results show that compared with the original system, the improved hydraulic system has higher control precision, faster response speed and higher system efficiency.
