Study on Frictional Vibration (Theoretical Analysis)

Abstract

In this paper, the theoretical analysis on the frictional vibrations which occur on the machinetool slide-way are described. To the contrary the past theoretical analysises in which the steady state frictional characteristics of slide-way are used, a new analysis in which the time effects are considered to the frictional characteristics of slide-way, is presented and both results are com-pared. In the results on the amplitude characteristic it is made clear that there are remarkable difference between the new analysis and the past ones. And a new point of view to the limit of the frictional vibrations in which the effects are considered is presented. By taking the new analysis the limit of the frictional vibrations can be more clearly explained than the past analysses in which the steady state frictional characteristics of the slide-way are used.
