- Abstract
The location of point excitation force is an important factor to influence sound radiation of underwater structure. A vibroacoustic model of a simply supported rectangular plate covered by decoupling coating is presented. The influences of the locations and the number of point excitation force to sound radiation power insertion loss are analyzed. The results show that: 1) The location of point excitation force has much influence to sound radiation power insertion loss; 2) The average sound radiation power insertion loss is closer to convergence as the number of point excitation force becomes larger; 3) When The location of point excitation force is closer to the corner of plate, sound radiation power insertion loss compares well with that of multi-point average. When plate model is used to measure the performance of noise reduction of decoupling coating, the location of point excitation force should be located of the position from a corner of the tested plate so that as many plate modes as possible are excited.
