Variable Mesh Stiffness of spur gear teeth using finite element method

Abstract

The objective of this paper is to determine the variable mesh stiffness of spur gear teeth using the finite element method. There are many factors for the variation of stiffness. In this paper only the numbers of contact tooth pairs and applied load are taken into considerations. For accomplishing the objective, a computer program named VMS (Variable Mesh Stiffness) has been developed, which needs only a little effort from the user. The program is capable of determining the plot of variable mesh stiffness and has also the ability of discretization of a single gear tooth, single pair teeth, and double pair teeth. The results of the developed program are found to agree with the analytical results.
