摘　　要：基于AMESim仿真平台,结合工程实例(软管恒张力控制系统),以A4VG闭式泵和专用设计的比例恒压控制阀组为基础建立数学模型,对泵的变量控制机构及远程恒压控制调节原理进行仿真分析。在对系统进行仿真和实验的基础上,分析了远程比例溢流阀调定压力和实际工作压力之间的关系和配置不同的阻尼孔对系统调定压力的影响。该系统比泵出口直接加溢流阀调压的方案具有更小的发热量及更好的节能效果,对于该系统在特定工况下的使用起到了一定的启发作用。Based on the AMESim simulation platform and engineering examples(hose constant tension control system),a mathematical model is established based on the A4VG closed pump and a specially designed valve for proportional and constant voltage control.The variable control mechanism of the pump and the principle of remote constant pressure control regulation are simulated and analyzed.On the basis of simulating the system,the relationship between the set pressure of the remote proportional relief valve and the actual working pressure,as well as the impact of configuring different damping holes on the set pressure of the system,were analyzed.Compared with the scheme of directly adding a relief valve to the pump outlet for pressure regulation,the system has a smaller heat generation and better energy-saving effect,which has played a certain inspiring role in the use of the system under specific working conditions.
