Prediction of vibration and radiation from large underwater structures is one of the most important research contents in engineering. The cylindrical shell structure is most common structure in engineering, and it is the main component of submarine at the same time. Shells with structural similarity have similar properties due to the similarity principle. Free vibration of the simple cylindrical shell...
This paper presents the trajectory data obtained from recent sea trials of the AUV Yumeiruka. Two sets of trajectory data were recorded for seven dives. One set of the data was recorded by the AUV's inertial navigation system, the other set was obtained from an SSBL system onboard the research vessel. Significant differences exist between the two sets of data, especially when the DVL on the AUV cannot...
