Dynamics of High-Speed Cam-Driven Mechanisms—Part 1: Linear System Models

Abstract

The dynamic response of the cam-driven mechanism is investigated for a variety of cam motion profiles. Based on a linear, lumped system model of single degree of freedom, the results of the response characteristics of the follower are presented in the form of nondimensional primary and residual shock response spectra. These spectra are also recasted in four-coordinate log-log grid forms. The extension of this approach to treat the system model of two degrees of freedom is delineated. Furthermore, the analysis of a two-freedom model of the cam-driven system was also undertaken to clarify the effects of many system parameters and for obtaining an optimal design. Fundamental design charts are presented.

Fault Diagnosis of a High-Speed Cam-Driven Pin Assembly System

“…Matthew and Tesar [6,7] applied a single degree-of-freedom mass-springdamper system to model a cam system and characterized dimensionless indexes for different speed. The concept of the primary and residual spectra was also raised to explore dynamic behavior of different cam profiles [1,[8][9][10]. Pisano and Freudenstein [11] developed a hybrid parametric model to simulate and investigate the dynamic response of a highspeed cam-follower system in gasoline engines.…”
