Vibration absorber for use in shipbuilding - has flexible vibration absorbing body with inserted masses altering vibration frequency

摘要

The vibration damper is used for heavy objects, in ship-building or for damping vibrations of concrete structures. On the surface of the object (1) is placed a body (10) which carries masses (12). The body is a composite vibration absorbing material. The body can be a cast resin, thermoplastics or thermosetting plastics of suitable stiffness and of suitable loss factor. The vibration absorbing masses can have plate or rod form. The latter can be made from steel or concrete or from stone and of mortar with heavy additives.
