概要

• 論文の詳細を見る

• The phenomenon of wheel fracture is studied experimentally using a wheel testing machine and it is found that wheel fracture can be analyzed by the concept of linear fracture mechanics. The critical condition of wheel fracture is given by the circumferential residual tensile stress in the wheel rim, the depth of a crack in the wheel tread and fracture toughness of the wheel material. And further, the influence of wheel configuration and drag braking condition on the residual stress in the wheel is examined.
