On the clutch dynamics with the approximations of resulting contact forces.

Abstract

The aim of the work is to present effectiveness of numerical simulations of clutch with frictional contacts, elaborated by some of the current articles in the last few years. The friction models assumes full developed sliding and the classical Coulomb friction law on each element of the contact with general shape and any pressure distribution. Then special modification of the integral model of friction force and moment are proposed. The approximants based on Padé approximants and their generalizations. In the work the clutch dynamics with contacts forces model is presented. The system was simplified to friction disk on rotating master disk. Two different configurations are investigated: coaxial and non-coaxial arrangement of the two disks. For the appropriate rotations speed, the system of non-coaxial arrangement can exhibit the ability to self-centering. The models based on generalizations of Padé approximants are compared with the simulation results obtained by the use of approximants based on Taylor’s expansion and models with exact integral expressions for friction force and torque components.
