Simulating and Analyzing Conflux Conditions of Hydraulic Synchronization Valve with AMESim

摘要: 液压同步阀是实现液压同步驱动的重要器件,其集流工况速度同步精度直接反映着液压同步阀的优劣。通过对液压同步阀的结构及集流工作原理分析,利用AMESim软件对集流工况进行建模,依据某型号液压同步阀的实际参数设置模型的各项参数并验证模型的正确性。在此模型基础上重点分析了对中弹簧刚度、弹簧座直径及可变节流口预设开度对液压同步阀集流工况速度同步精度的影响,得到了它们对液压同步阀集流工况速度同步精度的影响趋势。

Abstract: A hydraulic synchronization valve is an important device for hydraulic synchronization driving, and its conflux conditions such as conflux speed and synchronous accuracy decide its performance. After analyzing its con-struction and conflux mechanism, we establish its model with the AMESim software. With the actual parameters of a certain model of hydraulic synchronization valve, we set up various parameters of the model and verify its correct-ness. Then we analyze the effects of spring stiffness, the diameter of spring seat and the default opening area of the variable orifices on the conflux speed synchronization accuracy of the hydraulic synchronization valve.
