摘要
将船型变换程序接入到iSIGHT系统中,进行系列船型的变换,生成船型库;应用三维时域面元法(Wasim软件)对船型库中的系列船型进行耐波性的计算,将计算结果绘制成图谱,对耐波性与主要船型参数之间的关系总结归纳,并编写插值程序。将船型变换程序与插值程序相连,再接入到整个优化系统中,寻找到耐波性能更优良的船型。以某远洋渔船船型为例,验证了基于iSIGHT的耐波性优化系统的可行性。
A ship form change program was established based on iSIGHT platform.By controlling series of parameters,series of ship forms with different fineness coefficient and breadth-draft ratio were generated from original ship form.Detailed calculation to vertical movement of tuna series ship was conducted,and figures were drawn.The influence of main ship dimension and ship factors to vertical movement of tuna series ship in waves was concluded.According to the figures drawn,an interpolation program was developed.Together with the ship form change program,the two programs form a complete set of optimization system to search for ship forms that have most favorable pitch angle,head vertical acceleration,strike situation and roll angle,and the tuna series ship form with the best stability in movement in waves was found out.
