Abstract:

In order to investigate dynamics characteristics of eccentric cam mechanism more exactly, establishing dynamics model of the mechanism with considering some practical factors is needed. A new dynamics equation for eccentric cam mechanism with considering the friction between the cam and the follower and flexibility of the camshaft was established by using the finite element method and Lagrange approach. Taking this equation as mathematics model, the motion response of the mechanism was studied by using numerical method. According to the motion response obtained, the effects of the friction between the cam and the follower with the flexibility of the camshaft on the motion of mechanism were analyzed, and some correlative conclusions were obtained. It is shown from the conclusions that considering the factors of the friction between the cam and the follower with the flexibility of the camshaft is needed.
