摘要
The need to limit system vibrations makes the dynamic behavior of flexible high-speed cam-follower systems (as well as other machines subject to periodic motion) an important topic in the design of any such system. Researchers have worked extensively on this subject since before the turn of the century, both to determine dynamic behavior, and to improve and control that behavior. The goals in these analyses are to: 1) predict when and if the follower jumps off the cam; 2) determine the cam contact forces; 3) determine the linkage forces; 4) establish the closing spring requirements; 5) determine the magnitude of any follower impact with its seat; and 6) help optimize the system's dynamic response. This paper provides the following: a brief review of the literature on the dynamic analysis of flexible cam-follower systems; a recommended method for the analysis of such systems; and an extension of this analysis method to multi-input systems.
