| Abstract: | The design of the mechanical structure of general performance test bench for air spring in subway vehicle is introduced,including synchronous sprocket drive system,universal fixture,pressure loading mechanism,lower seat and air spring additional chamber,etc.Three key mechanical components: the pressure loading beam,lower seat and ball-screw are analyzed by finite-element method and the strength is checked.The developed general test bench for air spring performance provides an effective test means for the maintenance departments to judge the performance of the air spring system in metro vehicles. |
