SHIP POWER PLANT VIBRATION ISOLATION SYSTEM Russian patent published in 2014 - IPC F16F15/04 B60K5/12 

FIELD: transport.

SUBSTANCE: invention relates to means of protection against vibration. The system includes rigid supporting frame and vibration isolators connecting frame with base. Engine and diesel generator are mounted on supporting frame. The supporting frame is connected with four vibration isolators which are fixed on ship bulkhead. The bulkhead is connected with the frame by means of two elastic-damping elements made in the from of rubberised rope. Bottom of vibration isolators is connected with ship bulkhead via vibrodamping element. Elastic element consists of spring and lower and upper spring buffers made of elastomeric material. Vibration isolator contains flat elastic and frictional damping elements. The flat elastic elements are made as a package of arc-type elastic elements consisting of set of flat springs alternating in mutually perpendicular planes. Damping element is made as frictional one in the form of bushings with flanges on its butt ends, and rope length reeled on bushings in closed loop.

EFFECT: higher efficiency, simplified design of vibration isolation.
