EXACT RESPONSE ANALYSIS AND DYNAMIC DESIGN OF CAM-FOLLOWER SYSTEMS USING LAPLACE TRANSFORMS

This article presents Laplace transforms utilizing methods to determin e response of follower systems to motions machined on cams. The exact response of a follower system at any cycle, at any time, or in any tim e zone is directly determined without the need for numerical integrati ons. The method permits the study of response for many cycles to deter mine bent effect, the critical cam speeds, and possible follower jump conditions. Cam profile is corrected to eliminate static error and osc illate follower about exact position. Disk cams with translating rolle r followers with one and two degrees of freedom are considered in the article. Numerical illustrations are included, where results by other numerical methods (matrix exponential and phase plane-delta) are compa red.
