Global mesh stiffness calculation for lightweight spiral bevel gears

Book Contribution - Book Chapter Conference Contribution

This paper presents a methodology to accurately model the effects of gear blank topology on the global gear compliance of spiral bevel gears. The methodology is part of an ongoing development to create a gear contact code, which can be included in a general-purpose multibody code in order to enable system-level analysis of bevel geared transmissions. The contact compliance is decomposed into a non-linear local contact compliance and a linear bulk compliance. The linear contribution is extracted from a finite element(FE) representation of the spiral bevel gear. A dedicated software tool has been developed to automate the whole procedure, starting from the simulation of the cutting process to describe the gear teeth, over the FE model creation and finally the computation of the tooth bulk stiffness. The results for the tooth bulk compliance are stored in such a way that they can be read in into the multibody solver of LMS Virtual.Lab Motion. The paper concludes with a study of different lightweight topologies to show the importance of accurately capturing these effects
