Comparison of Skin Model Representations and Tooth Contact Analysis Techniques for Gear Tolerance Analysis

Abstract

To improve the tolerancing process in an industrial context, there exists a strong need for tolerance analysis to estimate the probability of scrap in an acceptable computer time and managing the accuracy of the results. The developed approaches for gear tolerance analysis based on simulation, depend on the type of the Skin Model representation, and on the type of behavior model. Therefore, this paper proposes a comparison of four Skin Model representations (discrete shape/parametric surface), and three tooth contact analysis (TCA) techniques (discrete approach/simulation of tangency of tooth surfaces) regarding accuracy of results, computation time and the adequacy with the standard tolerance practices.
