Modeling for Optimality in Design of Planetary Ring Gear to Reduce Stress Development--A Response Surface Methodology based Parametric Modelling Approach

摘要

Parametric modeling and optimization is emphasized in this work utilizing response surface methodology for a ring gear, the largest component in a planetary gear mechanism. The purpose of this paper is to disseminate design optimization based information for developing robust transmission system using finite element analysis. The methodology employed for assessing failure in gear components is modeled and optimized to reduce stress development. Analysis based on combination of statistical and mathematical modeling tools is employed for achieving desirable result. The mathematical modeling concepts exemplified for the ring gear can be used for other gear members. This paper serves the purpose of deducing strategic design related decision from design optimization concepts for achieving the best performance characteristics.
