| 内容記述 | This study refers to the relationship between dynamic characteristics and rubber shapes of some torsional vibration shear type rubber dampers by torsional stiffness and loss constants, which indicate their dynamic characteristics, against shape factors of rubber. The torsional stiffness in this study, which is called a complex torsional stiffness, consists of a typical torsional stiffness and a damping coefficient. The shape factor is determined as the ratio of free loaded area to loaded area of rubber. Four kinds of test shear type rubber dampers that only rubber shapes are different are used in this study. The test is engine experiment with the shear type rubber damper and exciting torsional vibration experiment. The experiment with shear type rubber damper is a high speed diesel engine test in the rated engine speed range with each test shear type rubber damper attached to the crankshaft system front edge. The frequency set in exciting torsional vibration test was made to be able to generator the frequencies occurred at the crankshaft system of the high speed diesel engine. Changing the shape of a pulley for exciting torsional vibration can change the exciting torsional vibration amplitude. The dynamic characteristics obtained from the experiment results are estimated in consideration of rubber shapes. The relation between amplitude dependence and the shape factor is particularly notified. As a results, the following knowledge can be provided. ［1］ The dynamic characteristics of the damper depend on shape factor. ［2］ The dependent tendency presents conspicuously with increase of the shape factor. ［3］ Rubber damper with smaller shape factor contributes to easily predict dynamic characteristics on the design stage. However, the damper of the small shape factor is hard to satisfy a torsional stiffness to tune to the torsional vibration mode of the crankshaft system of the high speed diesel engine. |
