Available in PDF, EPUB and Kindle. Book excerpt: Measurements were made on the propulsion system of the USS SIMON LAKE (AS-33) in February 1965 as part of a program to improve analysis procedures used by the Navy for predicting the longitudinal vibration of shaft propulsion systems. The objectives were to find the axial exciting forces and damping associated with the propulsion system of this ship, as well as to determine how the gear case, turbines, condenser, and machinery foundation affect longitudinal vibration. Alternating thrust in the shaft and longitudinal displacement of the gear case, low-pressure turbine, condenser, and machinery foundation were measured. A resonance was found to exist in the operating range, but it is not considered detrimental. The gear case, turbines, and condenser move essentially as one unit. A mass-elastic system derived from measured data includes a level effect acting on the foundation mass. The exciting forces are lower than usual, except at or near full power.

Book excerpt: 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.
