摘　　要：运用Adams软件仿真得到了采煤机行走轮轮齿受力载荷谱,并结合ANSYS软件对行走轮弯曲应力的分析结果,利用FE-SAFE软件,对行走轮的疲劳寿命进行仿真分析。特别地分析了表面粗糙度对行走轮疲劳寿命的影响,为合理提高轮齿表面质量提供理论依据,进而提高行走轮的疲劳寿命。The fatigue life of shearer sprocket is simulated by using FE--SAFE software based on shearer sprocket loading spectrum obtained from ADAMS software is combined with the results of sprocket bending stress achieved from ANSYS software. Particularly, the effect of surface roughness on fatigue life is analyzed, which provides theory Basis for improving reasonably the surface quality of sprocket tooth, and then the fatigue life of sprocket is increased.
