Dynamic Analysis of Silent Chain Drive System for Hybrid Car

Advanced Materials Research, 2013
Based on study of the power transmission system theory for hybrid car, a silent chain drive system which is used to transmit power between motor and gear box was designed. Using multi-body dynamic software RecurDyn, the dynamic behavior of the silent chain system was simulated, the chain tension, meshing impact load and instantaneous transmission ratio

Application of the non-circular sprocket in the timing chain drive system

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering
As a fundamental component of hybrid vehicles, the timing chain drive system significantly improves fuel economy while minimizing transmission error. A non-circular sprocket is used in a timing chain drive system to improve the dynamics characteristics of the system. In the scheme to reduce the crankshaft speed fluctuation, the relationship between the

Analytical Predictions for the Chain Drive System Resonance

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">The chain link and sprocket tooth impact during a meshing has been identified as the most significant noise source in a chain drive system. This paper first presents the theoretical derivation of the chain drive natural frequencies and mode shapes using the equations of motion from a stationary undamped chain drive
