A simple procedure for generating locally refined 2D quadrilateral finite element meshes of gears

This article describes a new procedure for automated generation of two-dimensional locally refined quadrilateral meshes gear drives. In this procedure, base mesh is generated using multiblock meshing procedure. Then, selected elements the are subdivided to obtain in certain parts teeth. The proposed completed with quality enhancement technique, which based on an optimization-based smoothing. It also includes strategies that allow automatically identify and refine those areas typically subjected elevated stress gradients. performance illustrated numerical examples, it compared other existing procedures, both terms distortion accuracy results.
