Abstract
An integrated model for the simulation of roller-chain drives
based on a multibody dynamics methodology is presented here in
order to describeits complex dynamic behavior. The chain is
modeled by masses lumped at the roller locations and connected by
translational spring-damper elements in order to take into account
the elastic flexibility of the chain and the energy dissipation at
the joints. The driver and driven sprockets are modeled as rigid
bodies that can be repositioned during the analysis in order to
simulate automatic tensioners or out-of-balanceshafts. The problem
of the rollers engagement on the sprockets responsible for the
polygonal effect is thoroughly analyzed and the induced impulsive
forces developed during that action are treated by a strategy
where kinematic constraints between sprockets and rollers are
added and deleted.
