Research on Random Load Characteristic Based on Mixture Distribution Model

CODEN: JTEVAB

Abstract

Random load is one of the inherent attributes of actual working load. It is regarded as the essential prerequisite in fatigue life prediction and reliability evaluation for enhancing the performance of mechanical systems and the safety of operators. This article proposes a statistics-based method of random load characteristic analysis to handle the variable amplitude fatigue loads collected from vehicle experiments. The mixture distribution model of random load was constructed according to the native behavior of gathered data, and the parameters of mixture distribution are estimated to fit the histogram of load counting. A case study of vehicle load is provided, and the goodness of fit is subsequently tested and verifies the credible result.
