Effect of crack propagation path on mesh stiffness of spur gears

Gear mesh stiffness is an important indicator for condition monitoring of gears as its value has been found to decrease with initiation of crack.

Summary:Gear mesh stiffness is an important indicator for condition monitoring of gears as its value has been found to decrease with initiation of crack. In the current study, the effect of crack propagation path on mesh stiffness has been investigated. Elliptical cracks with different values of semi major and semi minor axes have been considered with same values of crack lengths along these paths. ANSYS 19 software along with FRANC 3D has been used to model the gears with cracks induced. Structural analysis has been performed through Mechanical APDL. The values of mesh stiffness have been found to vary significantly with change in path of crack progression.
