盾构液压系统中插装溢流阀动态特性研究

摘要

In order to study transient characteristics of slip-in cartridge relief valve for cutter head driving system, this paper establishes the mathematical model. Also this paper introduces the method of simulation in simulink environment. At the same time, this paper discusses how to confirm primary influence factor for transient characteristics by changing parameters. The simulation result indicates that diameter of damping hole, volume of upper chamber and spring stiffness of pilot valve have obvious influence on transient characteristics for relief valve.%为了研究盾构刀盘驱动系统中二通插装溢流阀的动态特性,建立了相应的数学模型,介绍了在Simulink环境下对溢流阀进行动态特性仿真分析的方法,同时讨论了如何通过改变参数来确定影响溢流阀动态特性的主要因素.仿真结果表明溢流阀主阀阻尼孔直径、主阀上腔容积以及先导阀弹簧刚度的变化对溢流阀动态特性有较明显的影响.
