Research and analysis of time-varying meshing stiffness calculation considering crack fault
In this study,the spur gear with crack faults in the transmission system is taken as the research object.Considering the factors of tooth contact,bending,shearing,radial compression,and elastic deformation,an algorithm for correcting the time-va-rying meshing stiffness of the cracked spur gear pair is proposed.By simplifying the gear as a cantilever beam,the influence of the length,depth,and angle of the crack on the meshing stiffness of the spur gear is analyzed,and the correction calculation of the time-varying meshing stiffness is realized by MATLAB programming.The research results provide a theoretical basis for the crack failure mechanism of spur gear pair.
