Security Evaluation of Crankshaft due to Axial Vibration

종진동에 의한 크랭크축의 안전성 평가

Nowadays, the axial stiffness of crankshaft of long-stroke diesel engine is low compared to that of the old types of engine by increasing stroke/bore ratio and major critical speed might occur within engine operation speed. An axial damper needs to be installed in order to reduce the axial vibration of the crankshaft in the event of reduced or stopped axial damper function are discussed.
