Abstract
This paper extends the edge-based smoothed point interpolation method (ES-PIM) to the bending strength analysis of asymmetric gear with complex outlines. Five sets of asymmetric gears with the pressure angles of 20°/20°, 25°/20°, 30°/20°, 35°/20°, 40°/20° are generated by a special designed rack cutter, respectively. Four key factors, e.g. accuracy, convergence, convergence rate and computational efficiency of the present ES-PIM are checked in great detail on these five models, and distributions of bending stresses at the fillet of drive side are carefully investigated. The finite element method (FEM) is also used to calculate the above factors for stressing on the advantages of ES-PIM. Numerical results indicate that ES-PIM could provide more efficient and accurate solutions in stress field than the FEM, and is significantly suitable for stress analysis of the complicated asymmetric gears.
