download PDFAbstract. Centrifugal pendulum absorbers are passive dampers mainly employed nowadays to attenuate torsional vibrations in modern drivetrains to reduce fuel consumption and CO2 emissions. The absorber is linked to the drivetrain by means of a higher kinematic joint composed of slots and rollers, termed caged-roller joint. This work aims to investigate the contact between the rollers and the slots through multibody dynamics simulations. As a result, the sliding between the profiles, usually neglected in the design model of the caged-roller joint, is assessed and an estimate of the power loss is provided.
