602 An Experimental Analysis on Moving Silent Chain

Abstract

In this study the string vibration of the moving silent chain is discussed experimentally. It is found there are two kinds of string vibration occurred in a moving silent chain: one has the same frequency with meshing between chain and sprocket and another has the frequency that equals 1/2 of meshing frequency. The former is the resonant vibration excited by the meshing, but the later is the parametrically-excited vibration caused by the fluctuation of chain tension.
