Based on fatigue experiment analysis of welded box girder and the Miner fatigue accumulation theory,the fatigue life formula is obtained using Paris-Erdogan Equation as the mathematics model and in combination with the experiment data.

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.
