Efficient computation of stress and load distribution for external cylindrical gears

It has been extensively realized that tooth flank correction is an effective technique to improve load carrying capacity and running behavior of gears. However, the existing analytical methods of load distribution are not very satisfactory. They are either too simplified to produce accurate results or computationally too expensive. In this paper, we propose a new approach which computes the load and stress distribution of external involute gears efficiently and accurately. It adopts the open-quotes thin-sliceclose quotes model and 2D FEA technique and takes into account the varying meshing stiffness
