According to the requirements of nationalization of 6FA Gas Turbine Generator Unit(GTGU), the finite element method Cat-ia was used to analysis a 3D model strength of a flexible load coupling of 6FA GTGU.Through the comparison of analysis results, we described and discussed the range of several kinds of stress under various working conditions.Furthermore,the results present a theoret-ical base and feasible measure for structural design and material selection of this type of coupling.Basing upon the analysis results, some feasible suggestion and optimization scheme are given.
