Taking the compressor wheel of turbocharger for vehicle application as an example, to analyze the over-speed failure mode of compressor wheel of turbocharger, the uncertainty characteristics of stress and strength is studied. Taking the effect of structural characteristics, the randomness of stress and the dispersity of strength into account, the time-dependent reliability model of compressor wheel with over-speed failure mode is derived, which can embody the parameters of the number of symmetrical units, stress, strength and life index. Then, the reliability and failure rate of compressor wheel with over-speed failure mode are studied, and the method for determining the reliable life of compressor wheel is developed.
