摘　　要：油压减振器是铁道车辆减振的关键部件,其减振性能是由具有特殊结构的弹簧阻尼阀来实现的。根据实际减振器的结构和参数,在PRO/E中建立了其调压阀的三维模型。利用ANSYSCFX流体仿真软件的动网格技术,得出了调压阀在减振器不同工作速度下进行了动态流场分布情况,为减振器阻尼阀内部流道和结构的设计提供了重要的参考依据。Train damper is a key component of railway vehicles, its performance is decided by spring-damping valves of special structure. Three-dimensional model of pressure-regulating valve was built in PRO/E according to an actual damper＇s structure and parameters. Using dynamic mesh technology of Ansys CFX fluid dynamic simulation software, dynamic flow field distribution of the pressure regulating valve of the damper was obtained when it worked at different speeds. It provides an important reference for designing runner and structure of damper valves.
