Improved design and performance analysis of vibration damping device for railway freight bogie
At present, the variable friction damped bogie is widely used in railway freight transportation. Although it has good running performance and high warp stiffness, the bogie structure is complex, and the manufacturing and maintenance cost is high. In this study, a new variable friction wedge damper is proposed. Its structure is simple, and it can provide good warp stiffness. The bogie with the improved damping device has the characteristics of a variable and constant friction damped bogie. The relative friction coefficient of vibration damping performance is analysed and tested. Finally, the influence of wedge width on vehicle dynamic performance, including warp stiffness, critical velocity, line, and curve passing performance of the improved bogie are analysed.
