Vibration Analysis for a Huge Marine Engine using a Multiple Mode/Physical Coordinate Synthesis Method

다중 모드/물리 좌표 합성법을 이용한 대형선박엔진의 동적 모델링

This article explains the theory of multiple mode/physical coordinate synthesis method in order to analyze the dynamic characteristics for an huge marine engine. The theory leads to make a simulation code. The natural frequencies obtained from the simulation code is compared to those from a commercial analysis software, ANSYS. The simulation code is well reviewed.
