| Abstract: | In order to meet the special requirement of bulbous bow for acoustic performance,a staggered structure design of titanium alloy fairwater dome was carried out.This paper presents a basic configuration of such dome and investigates the water-tightness of bonded structure,and the cost-effectiveness of structural design.Finite Element Method was used to check the structural strength and the acoustic performance of the structure was examined.The results demonstrate that this configuration of the fairwater dome meets the needs of acoustic performance on structural design and which satisfies the requirements of sonar working at special operation condition. |
