Cam Follower

The vibration characteristics of a cam motion are generally presented by plotting the single degree of freedom residual vibration as a function of normalized operating speed. In this paper it is shown that by applying the methods of modal analysis, these residual vibration characteristics can be extended to the characterization of the vibration response of a multiple degree of freedom cam follower system.

High Speeds

The vibration in a cam driven mechanism due to drive system windup can be a serious problem at high speeds. A single degree of freedom model of this source of vibration shows that it is a self-induced nonlinear vibration. By dimensional analysis, two ratios are established to characterize the level of vibration. Maximum drive system windup and maximum radial follower force ratios are presented in chart form to characterize the vibration level. Systems studied are harmonic and cycloidal rises with open and closed track cam surfaces.
