Liu Yilun, Wang Ailun

College of Mechanical and Electrical Engineering,Central South University of Technology, Changsha 410083

Abstract:How to insert calculation extrapolation in plot, a new fatigue life prediction method, was studied in detail. The“step by step approach”handling method, combined with plot look-up and extrapolation, was put forward, which not only made it possible to extrapolate in plot, but also retained the advantages of simple and convenient application. Generally by repeating plot look-up for three times and extrapolating calculation, the satisfying results of predicted fatigue life could be obtained.
