A Study on the Dynamic Characteristics and Performance of Geislinger Type Torsional Vibration Damper for Two Stroke, Low-speed Diesel Engine

저속 2행정디젤엔진의 가이스링거형 비틀림 진동댐퍼 동특성 및 성능에 관한 연구

During the last decade, engine makers have developed new types or increasing power rate engines to enlarge theirs marketing shear in two stroke, low-speed diesel engines. As the results, these engines have increased the additional stresses due to torsional vibration more than old model engines. The torsional vibration dampers are necessary in order to reduce heigher additional stresses of intermediate and crank shaft in these engine. In this paper, the optimum designing of Geislinger type torsional Damper has been carried out, based on the theoretical conception. The dynamic characteristics and performance fo dampers are estimated by the measuring results obtained with the monitoring system of dampers and additional stresses of propulsion shafts.
