Abstract
We have clarified the effects of engine vibration reduction and the design of a torsional-bending damper pulley by an experimental analysis focusing on the vibration behavior at the front end of a crankshaft. The test was conducted using a newly developed device which can easily measure the vibration in radial and axial directions at the front end of a crankshaft during engine firing. This test confirmed that the vibration in the radial direction was dominant compared with that in the axial direction at the front end of the crankshaft. It was observed that a torsional-bending damper pulley works effectively to reduce torsional vibration, as well as to reduce the bending vibration of a crankshaft.
