Until now, the performance of this torsional damper has been clarified by the dynamic modeling, computer simulation and experimental analyses on torsional vibration of crankshaft system with the experiment device, which can qualitatively imitate the torsional vibration of engine crankshaft. However, it is necessary for us to verify that the dynamic model is effective and the practical damper can be designed for torsional vibration reduction of the crankshaft system in in-line 4-cylinder engine for automobiles. Because the rigidity, rotational speed, crank torque and the number of cylinders in the crankshaft system are quantitatively different from those of the experiment device and further the space for its installation is critically small for the weight and size reduction. Then, the experimental damper is newly designed and manufactured for the engine, and the experimental analyses are carried out. As a result, it is ascertained that the dynamic model is effective for this damper design and that this damper is superior than the practical rubber damper in the vibration reduction.
