水弹性力学在SWATH船体结构振动响应分析中的应用研究

摘要

文章以三维水弹性力学理论为基础,对小水线面双体船的船体振动响应特性进行了分析,预报了该船体在航行时受发电机激励下的振动响应,并与实船测量结果进行了对比,结论表明三维水弹性力学方法在船体受机械激励作用下对于船体振动响应的预报是有效的,可应用于工程设计.%The 3D hydroelastic analysis method is used for obtaining the vibration response characteristics of 150Ot SWATH ship hull. The hull vibration response of navigating ship produced by generators is predicted, and the predicted design loads are compared with the ship test results. The comparisons illustrate the feasibility of the hydroelastic analysis method in hull vibration assessment of SWATH ships.
