针对某型号气动单向阀打开过程中持续颤振现象,该文采用AMESim分析软件建立单向阀数值计算模型,对不同入口流量条件和气体介质条件下的工作特性进行仿真计算,得出此种类型单向阀产品的工作特性,当单向阀入口压力在0.8~1.5MPa阀芯振幅最大,压力高于3MPa阀门处于开度稳定状态,同时,开展单向阀特性试验验证,试验与数值计算结果较好吻合,为单向阀产品特性认识和正确使用提供重要指导.%For investigation a certain type of pneumatic check valve continuous flutter phenomenon in the open process, this paper adopts the AMESim analysis software check valve numerical calculation model is set under different inlet flow conditions and gas medium condi-tion of the simulation calculation. The work characteristics of this type check valve were obtained,the amplitude of check valve up to a max-imum when the entrance pressure between 0.8MPa~1.5MPa, and the spool at stable state if the entrance pressure exceed 3MPa. Meanwhile, . through developing the aerodynamic characteristics of the check valve test, and coincide with the numerical simulation is better for the check valve features to recognize and correct use of provide strong guidance.
