Research on the Vibration Characteristics of a Ship Engine-Base System

Abstract:

To study the vibration characteristics of a ship engine-base system, modal analysis is carried out to get the natural frequency and principal modes of the engine-base system. On that basis, the dynamic stiffness of base is further discussed and the dynamic displacement is calibrated in engineering field by superposition principle. Calculation shows that the base stiffness satisfies the requirement practical use, and likewise, the vibration characteristics of the base meet the design requirements.
