负载敏感多路阀流量动静态特性研究
Research on Dynamic and Static Flow Characteristics of Load-sensing Multi-way Valve
摘要
Abstract
The multi-way valve is a critical component in engineering machinery for flow distribution and actuator coordination.Its performance directly affects the machine's controllability.To address insufficient flow control accuracy and multi-parameter coupling in existing multi-way valves,this study focuses on a 16-diameter load-sensing multi-way valve.An electro-hydraulic-mechanical multidisciplinary co-simulation model is developed and validated through experiments.The research examines how the compensator spool flow force,spring parameters,damping holes,and the load-holding throttle edge influence the main valve static and dynamic flow characteristics.The results reveal that in static performance,flow force on the compensator is the main cause of flow error.This can be compensated by matching spring stiffness,though improper compensated stiffness may lead to flow"make a big bends".In dynamic performance,appropriately increasing the damping hole diameter and spring stiffness of the compensator improves flow response speed.Although the load-holding throttle edge enhances safety and control accuracy,it also limits flow capacity and introduces pressure loss,requiring a trade-off in design.关键词
