摘要/Abstract

摘要： 高压螺纹插装式溢流阀在工程机械中应用广泛，结构参数对其启闭特性、压力流量特性、稳定性、动态响应性存在交叉影响，设计不合理易造成插装阀在液压系统中出现压力冲击、振动、憋压等问题。基于高压螺纹插装式溢流阀原理构型，建立启闭、压力流量特性、稳定性和动态响应性数学模型，分析关键参数对其综合性能的耦合影响；以开启率、调压偏差、稳定性、动态响应性性能提升为优化目标，耦合结构参数为变量，现有性能及几何尺寸为约束，建立综合性能优化模型；通过NSGA-Ⅱ算法求解出Pareto解集，并对优化结果进行仿真与试验验证。研究结果表明，优化后开启率提高1.18%，调压偏差下降15.75%，阀前压力超调下降7.48%，响应时间缩短5.24%，稳定裕度明显提高。为高压螺纹插装式溢流阀综合性能优化提供理论指导。

Abstract: The high-pressure threaded cartridge relief valve is widely used in construction machinery. The structural parameters have a cross-impact on its opening and closing characteristics，pressure flow characteristics，stability，and dynamic response. Unreasonable design can easily cause pressure impact，vibration，and pressure suppression in the hydraulic system. Based on the principle configuration of high pressure threaded cartridge relief valve，the mathematical models of opening and closing，pressure flow characteristics，stability and dynamic response are established，and the coupling influence of key parameters on its comprehensive performance is analyzed. A comprehensive performance optimization model is established by taking the opening rate，voltage regulation deviation，stability and dynamic response performance improvement as the optimization objectives，coupling structural parameters as variables，and existing performance and geometric dimensions as constraints. The Pareto solution set is solved by NSGA-II algorithm，and the optimization results are simulated and verified by experiments. The results show that after optimization，the opening rate is increased by 1.18%，the pressure regulation deviation is decreased by 15.75%，the pressure overshoot before the valve is decreased by 7.48%，the dynamic response time is shortened by 5.24%，and the stability margin is obviously improved. It provides theoretical guidance for the comprehensive performance optimization of high pressure threaded cartridge relief valve.

Key words: threaded cartridge relief valve, comprehensive performance optimization, NSGA-II algorithm, cross coupling
