Abstract:
With the development of the logistics industry, the demand for efficient, high-capacity material handling equipment, such as stacker cranes, has grown significantly. As a critical load-bearing component of stacker cranes, the wheel-rail contact system is subtracted to higher operational speeds and load capacities, which lead to increased contact stresses and wheel tread wear. The degraded wheel profile caused by wear can deteriorate wheel-rail interactions, exacerbate vibrations, and subsequently reduce the lifespan of stacker cranes. This paper proposes a numerical model based on co-simulation to predict wheel tread wear of stacker cranes. The model combines a multibody dynamics model of the stacker crane, a wheel-rail contact model, and a worn profile update model. Additionally, a wear superposition method, i.e., a simplified and practical method, is developed to calculate the accumulated wear, enabling the prediction of the wheel wear under different work cycles with limited simul
ation iterations. The results show the accumulated wheel tread wear depth across various work cycles of stacker cranes, providing quantitative predictions while significantly reducing simulation time.
