Automation System Vibration Analysis Taking Environmental Factors into Consideration
Abstract: This paper aims to
investigate the vibration behavior of a propulsion system subjected to hull deformations
in a two dimension circumstance. As known that large scale ships have great
development in recent years which could cause much severer conditions among the
interaction between the propulsion system and ship hull. Excited forces from
these waves could make the ship hull deformed which further cause drastic
vibrations of the shaft system. As a result, the malfunctions of shaft
propulsion system are potential existed as the vibrations of the shaft always
exceed its maximum allowable values. This paper establishes a simplified model
of the large ship propulsion-hull system to analyze the vibration behavior of the
ship propulsion system subjected to the ship hull deformations. The hull
deformations were obtained as the excited forces under different sea
conditions. Then base on the simplified 2D model, the effects of propeller,
supports stiffness, the location of hull excitations, the amplitude of
excitations are discussed.
