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