| 摘 要： | 为了对比分析千吨级单体圆舭船型、深V船型、穿浪双体船型、三体船的耐波性能,采用二维半理论方法计算各船型在迎浪规则波中的摇荡及首中尾部垂向加速度的频率响应函数,其中应用时域格林函数求解水动力系数,应用谱分析计算各船型在不规则波中的运动有义值.结果表明,几种千吨级高性能船在波浪中的纵向运动性能均比常规圆舭船型优,其中三体船纵向运动性能最佳.计算结果可为该吨级舰船平台选型提供技术支持.

| Abstract: | In order to compare the seakeeping performance of conventional ship,deep-V ship,wave-piercing catamaran and trimaran,the pitch,heave and vertical acceleration of the ships was calculated with 2.5D theory,the hydrodynamic coefficients were calculated with time domain green function,and the spectrum analysis method was applied to calculate the significant motion of the ships in irregular wave.It shows that the longitudinal motion of all the high performance ships is more better than the conventional ship,and ... |
