The Frequency-Response Approach to the Design of a Mechanical Servo

The frequency-response method of analysis has proved extremely valuable in the design of electronic feedback systems. This paper illustrates the application of this method to the design of completely mechanical systems. Basic relations between the mechanical elements are pointed out and the necessary feedback concepts are developed for mechanical systems. These concepts are illustrated by the actual step-by-step design of an automatic contour-following lathe using entirely mechanical, hydraulic, and pneumatic control elements.
