摘要

针对基础振动对电磁换向阀压力-流量特性的影响

采用控制阀口压差模拟压力损失的方法

同时考虑基础振动引起的阀芯瞬态液动力和电磁力的变化

建立了基础振动下的电磁换向阀的数学模型和仿真模型

实验验证了模型的准确性

分析了基础振动参数和结构参数对阀的压力-流量特性和流量波动的影响。研究表明:小流量、低压降电磁换向阀对基础振动的顺应性较好; 基础振动下存在压力-流量特性降低区域和流量波动失效区域

压差为0.7 MPa时的压力-流量特性降低区域是0.4 MPa时的45倍; 弹簧刚度小于5 kN/m时

减小阀芯质量、增大阻尼系数有利于降低流量波动幅值。该研究对基础振动下电磁换向阀的选型和设计提供了一定的理论参考。

Abstract

Aiming at the impact of foundation vibration on pressure-flow characteristics of electromagnetic directional valve

the mathematical model and simulation model of the electromagnetic directional valve under the foundation vibration are established by controlling differential pressure of valve port to simulate the pressure loss. The transient flow force and electromagnet force under the foundation vibration are considered

and the accuracy of the model is verified experimentally. The influences of foundation vibration parameters and structure parameters of the valve on the pressure-flow characteristics and the flow fluctuation are discussed. The results show that electromagnetic directional valve with small flow and low pressure loss is more suitable for the foundation vibration environment. The pressure-flow characteristic reduction zone and the flow fluctuation failure area under foundation vibration are obtained

and the pressure-flow characteristic reduction area for the differential pressure of 0.7 MPa gets 45 times of that of 0.4 MPa. The flow fluctuation amplitude can be decreased by reducing the spool mass and increasing the damping coefficient and the spring stiffness ought to be less than 5 kN/m.
