Damper Pulley Bolt의 길이에 따른 Crankshaft Nose 응력 저감에 대한 연구

The objective of this study is to minimize the stress of the crankshaft nose. This research shows comparable results of the stress level at crankshaft nose fillet area which is subject to static loads due to the damper bolt load. This study evaluated how damper bolt types impact on the stress values of crank nose fillet area. The crank nose analysis consists of two steps respectively. First step is to do static analysis by applying the nose assembly loads to obtain stresses. Second step is to do dynamic analyses and combine both static and dynamic stress results to obtain fatigue reserve factors. The crankshaft static analysis utilized ABAQUS and the crank dynamic simulation and fatigue analysis were performed using AVL Excite Power Unit and FE-SAFE.
