This paper developed a multi-body dynamics model based on the multi-body dynamics simulation software RecurDyn. The dynamic characteristics of the timing chain drive system were investigated under various speed conditions. By constructing a dynamic model with 0.3% chain wear elongation
the dynamic characteristics analysis of the timing chain drive system under extreme operating conditions with chain wear elongation reaching its limit was accomplished.
