Authors Abstract
Content
Vibration has been the most objectable problem that inevitably occurs in high speed multi-cylinder diesel engines. The torsional vibration appearing at the crankshaft of the engine is the major source of the engine vibration. A torsional damper, being attached at the end of the crankshaft, has been widely used to reduce the torsional vibration.
For this purpose, various kinds of damper as examplified by a double-mass type and a viscous-rubber type have been subject to many investigations during these twenty years. However, less attention has been paid on dynamic characteristics of a shear-type single mass rubber damper in spite of its potential. Thus, the purpose of this study has been directed to establish the concept for designing a best tuned torsional rubber damper. In this work, rubber geometry is considered as one of the most essential factors influencing on dynamic characteristics of the rubber damper. The optimum tuning method, which would be able to decide a tuned damper to control the vibration, has been developed on the basis of the dynamic characteristics obtained from the fundamental oscillating tests of rubber specimens.
