摘　　要：针对某高空作业车平衡阀选型不当造成臂架下放振动问题,分析了平衡阀结构及工作机理,推导了平衡阀节流功能数学模型,并在AMESim中建立了举升平衡回路仿真模型,进而分析了平衡阀结构参数对液压系统稳定性的影响,研究结果为平衡阀选型提供理论依据。To solve the problem of the aerial platform vibrationin thelowing procedure, due to the choose of balance valve, the structure and working mechanisation of the valve are analyzed. The mathmatical model of balance valve for the throttle process is inducedand the simulation model of lifting balance circuit is built with the AMESim. Furthermore, the effect of balance valve structure parameters to the stability characteristic of circuit is researched. And the result of the research gives the theory evidence to the choose of balance valve.
