Kinetostatic of Knife Edge Translating Follower Under Dry Friction Conditions

Abstract

The paper presents the effect of dry friction upon the follower from a mechanism with rotating cam and translating knife edge follower. The contact between the ground and follower is regarded by equivalence as two non-conforming contacts positioned symmetrically about the symmetry plane of the prismatic pair, normal to the direction of velocity of the follower. There are discussed all possible contact solutions. An algorithm is proposed and verified concerning the identification of the actual contact case and the time when this position is reached. For an actual mechanism with imposed uniform rotational motion of the cam, there are found all reactions working upon the follower, for both assumptions: with and without dry friction.
