One Approach for Analyzing Natural Vibration of Submerged Cylindrical Shell Near a Rigid Wall
When conducting experiments in a water tank, the tank wall, is expected to make a difference on test results. One approach is proposed to get clear the effect of rigid wall on vibration of typical structure, i.e., finite cylindrical shell. The present method is verified by conducting
comparative analysis on coupled modal frequencies from present method and the FEM. When the shell is close to rigid wall, the rigid effect will lead to obvious reduction of coupled modal frequency, and it could be finally neglected if the distance is large enough.
