Abstract: Aiming at the problem of wheel tread damage in the service process of Chinese high-power heavy-duty locomotives, the shakedown theory and wheel damage function prediction methods are adopted to analyze from the perspective of dynamics. The six-axle locomotive model is established by using SIMPACK. Taking the JM3 standard tread and its different types of thin flange tread profiles standardized by the National Railway Administration of People’s Republic of China as the basic variables, the dynamic response simulation is carried out for targeted variables such as curve radius and running speed. Then the results are substituted into the shakedown-map and wheel damage function prediction model to predict the tread damage law. By expressing the results of working conditions and axle positions corresponding to different treads horizontally and vertically, the damage logic is specifically attributed. The result shows that the use of JM3 thin flange tread under some line conditions can effectively reduce the development of wheel damage, and based on this, the operation suggestions and repair strategies for alleviating wheel damage are put forward.
