Abstract

Dynamic equations of the intermittent motion of an indexing mechanism are derived in this paper. The vibrations due to the compliance of the mechanical components and the backlash effect of the gear speed reducer coupled to the mechanism are studied by means of a lumped parameters model of the system. Besides the non-rigid behaviour of the device, the computer simulations consider also the effects related to the electromagnetic behaviour of the motor and to the velocity controller. The numerical results, presented and discussed in the paper, indicate that the proposed model is feasible to foresee the dynamic behaviour of an actual system
