Efficiency and wear in cam actuated robotized gearbox using virtual model

In this paper the efficiency and wear of the cam actuator of a robotized gearbox are investigated, focusing on contact dynamics. A penalty method is used to simulate contact between the cam and the follower. The model is based on a finite element approximation of the theory of beam on continuous elastic foundation. The foundation modulus is computed using Hertz theory taking into account the change of principal curvature during the relative motion between cam and follower. This model has been embodied in a complete gear shifting simulation in order to compare contact forces and wear of different cam profiles. (A)
