基于AMESim的液压滑阀中位内泄漏仿真研究
Simulation Based on AMESim for Internal Leakage of Hydraulic Slide Valve
摘要
Abstract
The internal leakage exists widely in hydraulic system,and it directly affects the performance of the system.A three-position four-way reversing spool valve is taken as the research object,and an internal leakage fault simulation platform is built by the HCD component in AMESim.The effects of pressure,clearance height,cover volume,viscosity,eccentricity and diameter of valve core on internal leakage and system performance are considered.Combining with the simulation data,we use the orthogonal analysis to list the order of the primary and secondary factors that influence the internal leakage.The clearance height and the cover volume of slide valve are the main influencing factors of internal leakage in the neutral state.The clearance height has the most significant influence on the internal leakage,and the influence degree of eccentricity is the least,which provides a reference basis for design and processing of slide valve.关键词
