Sonar Dome Reliability XIX: Data Analysis of the USS Kauffman Sonar Rubber Dome

摘要

In August of 1992. a new Sonar Rubber Dome (SRD), instrumented with sensors forthe Sonar Dome Acoustic Deflection Measurement System, was installed aboard the USS Kauffman (FFG-59). The modification and deployment of the Sonar Dome Acoustic Deflection Measurement System to measure the deflection behavior of the SRD was an ambitious first time effort intended to provide calibration data for the University of Washington Applied Physics Laboratory's SRD finite element model. The purpose this report is to relate the findings of the data taken from FFG-59's SRD. This will include a comparison between the predictions of University of Washington Applied Physics Laboratory's finite element model and NRL's measurements. While the results from this comparison cannot be considered conclusive, they do suggest, from a dynamic perspective, that the SRD may be more rigid than initially predicted.
