비틀림 진동 계산 및 측정을 통해 고찰한 선박용 2행정 저속엔진 Crankshaft 파단 현상
Two Stroke Low Speed Diesel Engine Crankshaft Crack Phenomenon Study by Torsional Vibration Calculation & Measurement
초록
In the past two stroke low speed diesel engine were widely used for marine propulsion. these engine have many merit for example, higher thermal efficiency and durability. however, shaft vibration problem was continuously rise up due to large power of two stroke low speed diesel engine. specially, the initial stage engine revolution counter & stress has acculated. For that reason, sometimes occurred crankshaft crack accident. In this study, regarding the initial stage engine, trying to analyze what is cause the crack phenomenon using by latest torsional vibration calculation program & measurement equipment.
