Three main factors are discussed in detail: deformation of finite element mesh and remeshing, incremental step length, penalty coefficient. Moreover the control ways are provided.
The mesh stiffness of a pair of helical gears is calculated by substituting the variance of the contact line length for the variance of the instantaneous mesh stiffness.
