Abstract

It is very difficult to utilize traditional method for strength analysis and life calculation of heterogenic parts & components in mechanical products. In this paper, finite element analysis software Ansys is used to analyze hub of core parts and components in wind power generator unit. Addition of external load is subject to finite element calculation, so as to work out “stress hotspot” of unit load on the hub, namely “high load area”. Moreover, rain-flow counting method is used to calculate the number of times of stress circulation. According to the life curve of material, accumulative damage is calculated, and the life is determined.
