LONGITUDINAL VIBRATION OF PROPULSION SYSTEM ON USS CANOPUS (AS-34)

Abstract

As part of an effort to increase the adequacy of prediction methods used in shaft design, a study was made of the longitudinal vibration characteristics of the propulsion system on the USS CANOPUS (AS-34). The lever effect, previously detected on the USS SIMON LAKE (AS-33) was confirmed. This means that the amplitudes of the gear case, turbines, and condenser are roughly dependent on the relative heights of these components to the level of the shaft. The effective foundation mass, foundation stiffness, and thrust-bearing stiffness are computed from the measured response of the system. A resonance was found to exist in the operating range, but it was not considered detrimental. The exciting forces are lower than usual, except at or near full power.
