摘要
详述了船舶静力学计算及稳性衡准系统的一种设计与实现方案。系统由初始数据输入、系统内核计算、计算结果显示三个模块构成。系统实现是以Sybase作为后台数据库管理船舶静力学及稳性衡准计算的输入以及计算结果数据,以VisualBasic.NET作为开发平台来实现各项具体功能。对B样条的计算方法作为本系统中船舶静力学及稳性衡准计算的核心基础算法进行了详尽叙述。从船舶CAD设计文件中智能获取船舶型值信息(从而大大减少系统用户的输入工作量)是本系统实现的突出特点。
The paper presentes a design and implementation solution of the marine hydrostatic calculation and stability criteria. The system normally contains three subsystems such as data input, kernel computation and results displays. For the system implementation, Sybase was used as the background database to store the input data and the results of calculation, and VB. NET was selected as the devel- opment platform for the coding. B-spline algorithm, the basic and kernel of the system was discussed. The presented system has an excellent characteristic, obtaining offsets from ship design file of AutoCAD format intelligently, which alleviates the annoying, burdensome input work of system users.
