Simulation and Prediction Method of the Fatigue Cracks Life for Remanufacturing Shaft Parts

Abstract:

Combining the method of finite element analysis with fatigue life prediction, fatigue cracks on the shaft parts is analyzed with cyclic loading. Analyzing the shafts with different sizes of cracks in different locations, a simulation modal is established. Informed by analytical and numerical simulation method, the crack formation and propagation life could be calculated. With considering the relationship of "Frequency - crack - fatigue life - remanufacturing ", the remanufacturability of the shaft parts might be evaluated based on service condition. And in this paper, a more convenient way to detecting and predicting the fatigue cracks on shaft parts is given.
