Fatigue lifetime of the pavement structure under standard axle loading was calculated,and the concept of coefficient of different fatigue life was also put forward.

This paper based on the asphalt beam bending, for preliminary explore the fatigue equivalent temperature of asphalt pavement in Chongqing area , and fatigue life prediction model with different levels of confidence and reliability of the asphalt mixture as well as the fatigue life correction factor F of asphalt pavement.

On the basis of the statistic analysis of the constant amplitude fatigue life, the logarithmic fatigue life probability density function is deduced under arbitrary stress level and then the probability failure accumulative method is used to predict the fatigue life.

In this paper distribution function of roller chain fatigue lifetime are discussed and characteristic of Weibull distribution form parameter of fatigue lifetime that vary with its specification and loading are analyzed, then sampling inspection plan of lifetime of reliability and average lifetime are designes.

Substituting this stress intensity factor into Paris expression obtained by experiment, a prediction of remaining fatigue lifetime for a sucker rod is calculated.

Deviation of tradition fatigue lifetime prediction is bigger.

The analysis of rotor strength and fatigue life;

Prediction of fatigue life of packaging EMC material based on BP neural networks;
