基于低动力作用的高速铁路客货共运的货车选型研究
Research on the Selection of Freight Vehicles for Mixed Passenger and Freight Railways Based on Low Dynamic Interactions
摘要
Abstract
To select the freight vehicle for high speed railways with wide gauge and passenger and freight traffic,the dynamic responses of the vehicle/track systems are investigated for the high speed vehicle,the freight vehicle with the three-piece bogie and the freight vehicle with the frame bogie.The wheel/rail forces and the displacements of the rail are focused on for the freight vehicles with the three-piece bogie and the frame bogie.The TTISIM simulation software is adopted,based on the theory of vehicle-track coupled dynamics.The result shows that the safety index of wheel/rail of the three-piece vehicle is obviously higher than that of the freight vehicle with the frame bogie,and the maximum of the vertical force has exceeded the limit.Furthermore,frame-bogie vehicle has less influence on the track compared with the three-piece bogie vehicle.Consequently,it is rational to choose the frame-bogie vehicle for railways with passenger and freight traffic.关键词
