Stress Analysis of Thin-rimmed Spur Gears by Boundary Element Method

Abstract

In the present paper, a root stress analysis of the thin-rimmed spur gears by means of the 2-dimensional boundary element method (BEM) was carried out and the results were compared with those by the 2-dimensional finite element method (FEM) and those of the static loading test. The relationships between the number of elements in a gear model and the accuracy of the computed root stresses of the thin-rimmed spur gears by BEM were discussed. The BEM was shown to be available for the stress analysis of a thin-rimmed spur gear.
