变量液压泵稳态仿真模型

Study on the Steady Analysis Model of Variable Displacement Hydraulic Pump

提出了一种新的变量液压泵稳态仿真计算模型 ,恒流源恒压源模型。该模型将变量液压泵等效为液阻、压力突变、恒流源构成的一般液压元件。在对液压系统进行稳态仿真过程中 ,使用该模型 ,变量液压泵以普通液压元件的形式出现在系统回路 ,不必将其简化为一个边界点。

This paper presents a new model of the steady state analysis of variable displacement hydraulic pump which is called the invariable pressure and invariable flow model. By the new model, a variable displacement hydraulic pump is simulated by the ordinary hydraulic component with hydraulic resistance, abrupt pressure change and invariable flow. The variable displacement hydraulic pump exists as an ordinary hydraulic component in the system and needn't to be simplified as a boundary point when a system model is established in analyzing the steady state characteristic of a hydraulic system.
