| 摘 要： | 1. INTRODUCTION Induced by unbalanced mechanical forces and moments, underwater structures vibrate and radiate The main form of underwater structures, such a submarine, is reinforced double cylindrical structure immersed in water, with fluid media filled between th double cylindrical shells. In essence, this is a coupling problem between fluid and structure. Multipl methods have been used to estimate radiation leve from underwater structures1-9]. Musha10] and Chertock11] estimate the …

| Abstract: | An experiment on radiation from double cylindrical structures was held in an open-air pond. Radiation responses from one-point harmonic force driven model and two-point stochastic forces driven model were measured. Numerical results show a good agreement with the experimental results. Possible errors are analyzed. |
