ANALYTICAL DYNAMIC-RESPONSE OF ELASTIC CAM-FOLLOWER SYSTEMS WITH DISTRIBUTED-PARAMETER RETURN SPRING

An analytical method of solution for the high-speed dynamic response o f a lumped/distributed parameter model for cam-follower systems is dev eloped. The model combines the distributed parameter model of the retu rn spring with a viscously damped, single degree-of-freedom, lumped mo del of the elastic follower train. The cam event is considered as a pe riodic motion, of period 360 deg, and is represented by its Fourier se ries approximation. Linear systems approach utilizing four-pole parame ter representation of lumped and distributed elements is adopted. The applicability and the accuracy of the method are verified with the aid of the experimental results reported in recent literature on the dyna mic response of a high-speed cam-follower system.
