Performance Analysis and Design of the Braking System of a Rail Vehicle
This paper aims to improve the safety and reliability of the braking performance of a certain rail transport vehicle.On the one hand,a single objective mathematical optimization model and a drum brake calculation model are established to verify performance parameters such as maximum braking force,maximum dwell slope under full load,braking distance,ultimate load capacity,and bearing life;on the other hand,the simulation analysis of the structural strength of the core components of the target vehicle is carried out using ANSYS/Workbench software,including static stress analysis of the frame,axle stress analysis,and wheel stress analysis.The parameter verification results indicate that the braking performance of the target vehicle meets the usage requirements.The simulation analysis results show that the ultimate failure node of the frame is located at the topological arc of the inner and outer vertical plates,and the connection area between the inner vertical plate and the top plate of the frame.It can be seen that the braking performance of the target vehicle meets the usage requirements,and the structural design margin is relatively high,which provides guidance for subsequent structural improvement and lightweight topology optimization design.
