Controlling the Frequency Content of Inertia Forces in Dwelling Cam-Follower Systems

Abstract

Background. Cam-driven machines are frequently manufactured with the intent that they be installed in many different end applications, each with its own natural frequencies. A cam-driven component that performs well in one end application can excite obnoxious or damaging vibrations in another. Method of Approach. A Lagrange multiplier technique is presented that optimally modifies follower motion such that unwanted inertia force frequencies are suppressed. Results. An example problem illustrates the method and presents results. Conclusions. The technique provides a robust customization procedure, permitting the use of a cam-driven component in a wider variety of end applications.
