In this paper, we first describe the characteristics of engine damping that are necessary for the calculation of torsional vibration. Secondly, we describe an experiment in which two crankshaft pulleys with a torsional rubber damper are fitted to a 6-cylinder, high-speed diesel engine. The torsional waveforms of the damper inertia ring and the pulley are measured by means of phase-shift torsiograph equipment. The measured waveforms are harmonically analyzed and the dynamic characteristics of the stiffness and the damping are investigated from experimental viewpoint. In addition, torsional waveforms are calculated by means of the simulation method of torsional vibration, in which a transition matrix method is adopted. As a result of comparisons with experimental data, certain dynamic characteristics of pulleys with the torsional rubber damper have been made clear.
