摘　　要：在对典型双向液压锁的结构分析基础上,基于Amesim建立了元件的仿真模型,并构建了相应的液压系统模型。通过系统仿真分析了双向液压锁实现安全功能的动态过程,研究了在空载和负载不同工况下,双向液压锁阀芯的开启和闭合特性,发现阀芯的开启状态与系统负载和伸缩状态之间的关系,为双向液压锁的日常使用和故障诊断提供依据。Based on the structural analysis of typical bilateral pilot-controlled valve and Amesim,the simulation model of components and the corresponding hydraulic system model are established.Through the simulation of the system,the working process of the safety function of the bilateral pilot-controlled valve is analyzed,the opening and closing characteristics of the valve core of the bilateral pilot-controlled valve under different working conditions of no-load and load are studied,and the relationship between the opening state of the valve core and the system load and expansion state is found,which provides a basis for daily use and fault diagnosis of the bilateral pilot-controlled valve.
