Comprehensive Performance Optimization of High Pressure Threaded Plug-in Relief Valves
摘要
Abstract
In views of the coupling of structural parameters affecting different performance of high-pressure threaded plug-in relief valves,it was difficult to optimize the comprehensive perform-ance,a multi-objective particle swarm optimization algorithm was proposed to optimize the compre-hensive performance.Based on the structural characteristics of high-pressure threaded plug-in relief valves,the mathematical models of opening and closing characteristics,pressure regulation deviation and stability were established.Based on the first-order sensitivity analysis of the influences of struc-tural parameters on the dynamic response,according to the mapping relationship between structure and performance,with the opening rate,pressure regulation deviation,stability and dynamic response performance improvement as the optimization objectives and coupling structure parameters as varia-bles,a comprehensive performance optimization model was established,and the optimal solution of coupling structural parameters was obtained in the form of Pareto set by particle swarm optimization algorithm.The experimental results show that after optimization,the pressure oscillation of the high pressure threaded plug-in relief valves is reduced by 22.7％,the opening rate is increased by 1.5％,the pressure flow gradient is reduced by 14.58％,the pressure overreach in front of the valves is re-duced by 14.1％,the response time is shortened by 9.52％.关键词
