Simulation and Test of Flow Control and Micro-motion Characteristics of LUDV Multi-way Valve
Based on the principle and structure of the LUDV multi-way valve,AMESim simulation software was used to build a load-sensitive system simulation model.The precise flow control and micro-motion characteristics of the hydraulic system using the LUDV multi-way valve were analysed.A variable pump load-sensitive hydraulic system was built using a domestic load-sensitive multi-way valve.Through prototype testing,the relative error between numerical and experimental results is within a reasonable range of 5％.The flow accuracy of the working port is stable within the error range of 10％of the set flow under different load conditions.Therefore,the correctness of the simulation platform and the reliability of domestic multi-way valves were verified,which provide a theoretical basis for the research,development and optimization of hydraulic products and the performance improvement of hydraulic systems.
