VIBRATION SURVEY TECHNIQUES

The paper presents fundamental vibration survey considerations and discusses classical hull girder vibration and main propulsion machinery longitudinal vibration. The results of a typical hull girder vibration survey are presented. Elementary considerations of the effect, on blade-frequency hull girder vibration, of changing the number of blades on the propeller are discussed. The SNAME Bulletin No. C-1 Code for Shipboard Vibration Measurements by Panels HS-7 and M-20 ( 1969 ) is summarized with empahsis on the instrumentation aspect. The subject of local vibration is treated by means of some typical examples and the instrumentation requirements for this type of study are discussed. The performance characteristics of the Askania Hand Vibrograph are outlined. A vibration survey conducted by the author on a river towboat in order to investigate a rather unusual vibration problem is described.
