The cause of fatigue fracture in gearbox housing of coal mining machine cutting part (CPGH) is analyzed in this paper. Considering the effects of lowfrequency external excitation caused by coal cutting and highfrequency internal excitation caused by gear meshing, systematic studies of force analysis and local resonance analysis are employed. Force analysis is proposed to obtain the region of ...
