EQUIVALENT LOAD METHOD FOR FATIGUE LIFE ANALYSIS OF LUGS UNDER OBLIQUE LOADING

LI YanBin / DONG DengKe / GONG YunZhao

First of all,stress analysis of lug under different loading angles was carried out. For the fatigue life analysis of lug under tension-compression loads,the compression load was treated equivalently,and the effective equivalent load factor λ was obtained. The fatigue load spectrum was equivalent to P_max λP_min,and then the fatigue life of lug structure was obtained by the Detail Fatigue Rating（ DFR） method. Finally,the method was proved by the fatigue test of lug in 45° angles load,which proves that the method is practical in engineering.
