THE YARROW CONSTANT-POSITION MOUNTING SYSTEM

A unique system designed to overcome problems arising from the vibration of rotating and reciprocating machinery is pressurizing/damping fluids. The machinery package is rigidly attached to the baseplate--or raft--which in turn is supported and actuated by mounts which control the raft movement relative to the ship's structure in all six degrees of freedom. The machinery is thus isolated from the ship's structure by fluid, with the exception of the service connections and the output shaft. This active mounting system offers several advantages over a passive system, such as ease and accuracy of initial alignment and freedom from creep during service, and a high damping characteristic at the system natural frequency, among others. The design, operation, installation and servicing of this mounting system are all discussed, as are some special applications that can be treated by this system.
