A Chatter Box - Investigation of Dynamic Response Across a Gap

Abstract

Virtually all mechanical devices contain several components which are joined or articulated, at joints which must have some clearance. The clearances are required for ease of motion during assembly and/or operation. These clearances produce complex motions when the assembly is subjected to transient motions such as the recoil of a cannon system. This work takes a geometrically simple chatter box system and subjects it to a simple haversine motion using 4 different time frames. The two contact surfaces are given different clearances in an attempt to study one system under a variety of different conditions. The contact stress and the motion of the central slug are shown for all of these 16 cases.
