摘要：
A simplified physical parameter model was established for a high-speed train yaw damper where hydraulic oil circulates in a single direction. It was based on the Kasteel's complex physical parameter model, with the reasonable simplification of the damping valve and check valve. The static and dynamic characteristics of the yaw damper were then compared by means of numerical simulation and experimental tests. At last, the hunting stability of a railway vehicle was compared by using the simplified physical parameter model and traditional Maxwell model. The results show that neither the traditional Maxwell model can accurately describe the dynamic characteristics of the hydraulic damper, nor the complex physical parameter model can be used for the vehicle dynamics simulation for its low calculation efficiency despite its high accuracy. The proposed simplified physical parameter model can accurately reproduce the complex dynamic behavior of the yaw damper, with high efficiency that can be used in the vehicle dynamics simulation. Under high conicity cases, the Maxwell model will overestimate dynamic damping of the yaw damper, resulting in large errors in stability calculations compared to the simplified physical parameter model. © 2021, Department of Journal of the China Railway Society.
