Gear-Drive Parametric Design with Femap Express Stress Analysis

Abstract

Modeling and finite element analysis functions were combined in Solid Edge to optimize gear parameters. Gear parameters optimization objective and procedure in different conditions were summed up. A complete Excel file was created. An involute gear parametric model was established which was interlinking with the Excel file. And the model’s accuracy would not alter with the diameter’s change. The wizard software for gear drive design and parameter optimization was developed on platform of Solid Edge by Visual Basic tool. This application can guide users getting the initial parameters and optimizing the parameters by the circling method of diminishing parameters, analyzing the precise gear root stress with Femap Express module, and diminishing them again. Users can get a gear model which has a smaller diameter and smaller module and satisfies strength demands.
