SUBMARINE SEA-CONNECTED PUMPING SYSTEM NOISE REDUCTION STUDY - PHASE I,

Abstract

This manual presents the results of an analytical and experimental investigation to determine necessary criteria for the sesign of quiet seaconnected piping systems. The work accomplished may be summarized as follows: (1) Some general design guidelines are suggested. A procedure for calculating the radiation spectrum of fluidborne noise from the pump noise spectrum was developed. The method of estimating sound radiation due to pump vibration transmitted through the piping system structures to the sea chest and hull plating was demonstrated. A sea chest simulator experimental test loop was designed, constructed, and utilized. The experimental results can be used to modify the theoretical sound transmission transfer functions which were analytically determined for a number of pipe element configurations. (Author)
