摘要
针对某内河大型双体客船,开展波浪载荷的模型试验和仿真预报研究.建立双体船波浪载荷预报的水动力仿真分析模型,获得双体船的垂荡、横摇、纵摇等运动响应特性,以及剪力、弯矩、转矩等波浪载荷沿船长方向的分布特征,研究航速对波浪载荷的影响规律.设计加工双体船缩尺模型,开展了波浪不同波长和浪向角下的载荷试验研究,并将仿真结果、试验结果进行比较,吻合较好.
Abstract
The hydrodynamic analysis model for predicting the wave load of the catamaran was established to calculate the dynamic response of the catamaran under the heave,roll and pitching states,as well as the distribution characteristics of the wave loads along the ship length,the speed influence characteristics of the wave loads,such as shear force,bending moment and torque.The scale ratio model of catamaran was designed and made to carry out the model test of wave loading under different wave incidence with wavelength and angle.The numerical results were compared with that of test,to verify the reliability and ac-curacy of the simulation model and results.
