The paper presents computational modelling of a torsional damper in the ADAMS Multi-Body System. Both rubber and viscous torsional dampers are integrated by using rheological models into the dynamic system based on modally reduced bodies. The hysteresis damping model is considered for the rubber damper, while in the case of the viscous damper, the optimization of the model parameters to the data from the manufacturer is used. Torsional dampers are used in the mass-produced naturally aspirated four-cylinder spark-ignition engine and its derived variant with an unconventional crank train with low friction losses. The results of the simulations are compared with data obtained experimentally by a laser vibrometer when measured on an engine.
