摘要
介绍了AMESim软件的主要特点,分析了混凝土泵车臂架多路阀的结构、功能和主要技术参数,阐述了该多路阀的建模目标和难点,应用AMESim构建了臂架多路阀的模型结构并设置了主要参数,通过模型的性能测试和参数分析,结果表明:对于较为复杂的工程机械多路换向阀,可以采用AMESim液压元件库中现有模型组合构建仿真模型;臂架多路阀的流量由流量阀弹簧预紧力和主阀芯开口共同决定。
Main features of AMESim were introduced, The multi-way valve struetrue, function and performance parameters used in boom control of pump truck were analyzed, the target and method of multi-way valve model building were discussed, the simulation mode was built by AMESim and main parameters were set. The results show that complex multi-way valve of construction machinery can be modeled based on ready-made models in AMESim hydraulic library. The flow rate of boom multi-way valve is decided by spring preload of flow control valve and main spool openings.
