Multi-Body Dynamic Chain System Simulation Using a Blade Tensioner

An increasing number of chain systems have used low cost blade tensioners. However, its functional mechanism had not been logically figured out. One reason for this is that a blade tensioner generates large transversal vibration. Consequently, in the case of the longitudinal model, the load prediction accuracy was inadequate. Accordingly, a link-by-link model was created, allowing transversal vibration to be taken into account. As a result, the features of a chain system using a blade tensioner were clarified, thus enabling the chain load and behavior to be predicted with a higher degree of accuracy than before.
