摘　　要：旋压机横向进给广泛采用电液伺服闭环控制,横向进给的退让量参数对旋压产品的质量有直接影响,是工艺人员最为关心的问题。以自动控制原理为理论基础,建立阀控非对称伺服油缸电液伺服系统的数学模型,采用MATLAB软件的Simulink模块作为工具对数学模型进行模拟仿真。以某三轮旋压机横向进给电液伺服系统为研究对象,分析斜坡信号在不同速度和不同负载时的退让量指标,同时进行工艺试验,将工艺试验退让量结果与模拟仿真结果进行对比分析,验证了模拟仿真的正确性,得到了旋压机横向进给电液伺服系统斜坡响应的稳态误差与进给速度的关系和阶跃响应的稳态误差与负载变化的关系。Electro-hydraulic servo closed-loop control is widely used in the transverse feed of spinning machines.The retreat amount parameter of transverse feed has a direct impact on the quality of spinning products,which is the most concerned issue for craftsmen.Based on the principle of automatic control,the mathematical model of the valve-controlled asymmetric servo cylinder electro-hydraulic servo system was established,and the Simulink module of MATLAB software was used as a tool to simulate the mathematical model.Taking the transverse feed electro-hydraulic servo system of a three-wheel spinning machine as the research object,the retreat amount index of the ramp signal at different speeds and different loads was analyzed,and the process test was carried out at the same time,the results of the process test retreat amount were compared with the simulation results,the correctness of the simulation was verified.The relationship between the steady-state error of the spinning machine electro-hydraulic servo system ramp response and the feed speed and the relationship between the steady-state error of the step response and the load change were obtained.
