Resilient wheels are widely used in urban tram systems in China due to the wheels’ good performance on vibration and noise reduction.Application of resilient wheels to subway vehicles is also underway.Aiming at the problem of temperature and stress of a subway resilient wheel generated by tread braking,a mechanical-thermal finite element model was established and it was used to calculate the temperature of the rubber layer and the internal surface stress of the rim,and compared with the laboratory braking thermal test data.Comparing the elastic wheel stress distribution considering only mechanical load and mechanical-thermal coupling,it was found that the braking thermal stress had great influence on the rim stress.The orthogonal design method was used to study the effect of the rim thickness,the rubber layer angle and the elastic modulus of the rubber layer on the maximum temperature of the rubber layer and the internal surface stress of the rim in different line situations.The results show that increasing the thickness of the rim reduces the rubber temperature and the mechanical-thermal coupling stress;when the thickness of the rim is less than 55 mm,the mechanical stress dominates,and when the thickness of the rim is greater than 60 mm,the temperature stress dominates;the effect of the elastic modulus of the rubber layer is non-monotonic,for a given rim thickness and a rubber layer angle,there exists optimal value.
