摘　　要：随着社会资源开发,起重机的使用逐渐增多,同时施工作业时由于支撑不稳定引发侧翻等问题引发的安全事故也在上升。本文提出运用液压锁在支腿系统工作时能够将其锁死,防止其发生“软腿”,提高起重机支腿的支撑稳定性,设计优化起重机支腿液压系统。利用AMESim对其系统建模并进行仿真分析,通过闭锁压力变化曲线分析系统工况。结果表明:整个支腿液压系统能够安全稳定的运行,满足起重机的工况要求。With the development of social resources,the use of cranes has gradually increased.At the same time,problems such as rollovers caused by unstable supports during construction operations have caused an increase in major safety accidents.This paper proposes that the hydraulic lock can be used to lock the outrigger system when it is working,prevent it from"soft legs",improve the support stability of the crane outriggers,and design and optimize the hydraulic system of the outriggers of the crane.Use AMESim to model the system and perform simulation analysis,and analyze the system working conditions through the blocking pressure change curve.The results show that the entire outrigger hydraulic system can operate safely and stably to meet the requirements of the crane's working conditions.
