摘要

摘要: 研究了恒压控制轴向柱塞变量泵的动态响应特性。利用AMESet自定义了两个关键的轴向柱塞变量泵组件，参照Rexroth变量泵样本的测试条件建立了负载模型，并在AMESim 中建立了恒压控制的轴向柱塞变量泵动态特性测试模型，获得了变量泵在阶跃负载作用下的动态特性仿真曲线。通过对比阶跃负载条件下的仿真曲线和样本曲线验证了模型的准确性。仿真分析结果表明，变量泵的输油脉动主要受压力控制阀的阀芯直径和行程缸活塞直径的影响，适当提高行程缸预紧力可以提高变量泵的响应时间。

Abstract: The dynamic characteristics of an axial piston pump with pressure control were studied. Its two key components were customized by AMESet. Its whole test model and load model based on the product sample of Rexroth were established in AMESim. The dynamic curves of variable displacement pump were obtained under load step conditions. The validity of the models was verified by comparing the simulation results with the dynamic operating curves of the product sample of Rexroth. The simulation results show that the variable displacement pump pressure pulsation is mainly affected by the spool diameter of the pressure control valve and the piston diameter of the piston stroke and that an appropriate increase in stroke cylinder preload improves the dynamic response time of variable displacement pump.
