A torsional damper is attached to a crankshaft to control the torsional vibration of the crankshaft system. However, the damper, which has a rubber part in between a damper mass and a damper hub, possesses a three-dimensional inertia moment and an inertia mass that could excite the crankshaft system. This paper discusses the generating mechanisms of the bending strain on the bolt to fasten the damper hub to the crankshaft, from the measured bolt strains and the measured behavior of the damper mass and the damper hub under the engine operating conditions.
