The Comparison of the Estimation of Bridge Crane Real-Time Fatigue Life Based on JIS and FEM

This paper aims to achieve a crane real-time software programming methodology for estimating the fatigue life,the core idea of this method is to capture the whole life cycle of real-time stress load,gets real-time fatigue life results by using JIS and FEM and compares the two results.The method is more accurate than the traditional one and has guiding significance for real-time fatigue life estimation of port machinery.
