Abstract
In this paper, based on the multi-body dynamics software RecurDyn, flexible multi-body contact mechanical model of Hy-Vo silent chain and sprocket is established, the dynamic contact stress is studied when the Hy-Vo silent chain is meshing with sprockets, the stress variation of heterogeneous pins contacting is analyzed when the angle of two adjacent links varied. A new method is proposed to measure the pitch of the link in the realistic condition. This paper's conclusion provides an important design basis for the structure design and weight save design of the Hy-Vo silent chain.
