Dynamic analysis of lightweight gears through multibody models with movable teeth

Abstract. This paper aims the study of lightweight gears through a novel approach based on multibody model contact-based with pseudo-rigid teeth. method considers teeth as bodies attached to main body revolute joints and torsion springs precomputed stiffness. Thanks this approach, lightening is considered by varying value stiffness parameter. To validate method, first step compares Transmission Error computed Finite Element in quasi-static operating conditions. The second highlights behaviour Error, increasing rotation speed.
