    Abstract
  • Combining the dynamic response of vehicle under the excitation of track spectrum with fatigue strength theory, the wheel axle of China Star high-speed power car was taken as example, the nonlinear dynamics model of the power car was set up, the running property of vehicle on typical railway was simulated, and the random loads acted on vehicle wheelsets were obtained.Based on the nonlinear random cyclic constitution of the axle material, the finite element model of the wheelset was established, the stress time history of key region of the wheelset under the random loads was calculated, and the stress spectrum of hazard sections of the axle was obtained by statistical analysis.Using fracture mechanics theory and accumulative damage theory, the fatigue life of the axle was predicted, and its reliability was analysed.When the reliability was 0.9, the fatigue life was 16 years.
