Simulation study on the stability of train wheel rail adhesion
WANG Jian-biao
Abstract：Based on the parameters of the transmission system of a certain type of high-speed train in China,the dynamic model of the single-wheelset transmission system was established using Matlab/Simulink software,and the influence of the wheel-rail adhesion stability characteristics and the transmission system connection parameters on the adhesion stability was studied based on the model.The results show that the stability of wheel-rail adhesion is related to the velocity and creep rate.The motor output shaft adopts a solid shaft to have better wheel-rail adhesion stability than a hollow shaft,and an appropriate increase in the rigidity of the gearbox mounting is helpful to the wheel-rail adhesion stability.
