| Abstract: | Fatigue reveals a important complex process, which is affected by many uncontrolled factors. The present method of fatigue-life calculation is based on traditional formulae, which have intricate process, considerable error. With the fast development of artificial neural network(ANN), it is possible that fatigue-life prediction(FLP) is simulated by ANN. In the paper, a method for the study of FLP is proposed. The factors that influence FLP are analyzed, improved BP network is applied to the simulation of FLP, the results show that the simulation can get better result than normal method. |
