摘要
解析推导双三角型和U型组合阀口过流面积及等效阀口面积特性,用MATLAB编程得出计算结果。在S imu-link上对变量泵负流量控制数学模型进行仿真,计算通过改变阀口的尺寸参数来观察对其动态响应影响。
The orifice area characteristics and the equivalent orifice area of one combined shape orifice valves are analyzed, and the orifice area are calculated by MATLAB. The mathematical model of the negative flow control of variable - displacement pumps is established, and the simulation is carried out using Simulink, meanwhile the factors affecting the dynamical characteristics are discussed.
