Abstract
A cam mechanism with sliding follower was run using two sets of linkages. The first, which was made of solid sections, resulted in large-amplitude vibration on the acceleration record. The second, made of hollow sections, gave acceleration records showing less vibration. Vibration analysis tests were carried out using an impact test and a white-noise test to compare the natural frequencies of the two mechanisms. The paper suggests that the design of cam-driven mechanisms should ensure that their lowest natural frequency is higher than the highest frequency with a significant component in the acceleration spectrum of the follower. A simplified method of calculating the natural frequencies is appended. The experimental procedures are described and the pitfalls are highlighted.
