基于CADDS5和VB的三维船体结构重量重心及材料统计计算系统

Statistics Computing System for Strucuctural Gravity Center and Material of Three-dimensional Hull Based on CADDS 5 and VB

根据平面图计算船体结构重量重心不但繁杂、耗时,而且难以保证计算结果的准确性。采用三维设计软件进行舰船设计,虽然具备计算功能,但仍然不能满足实际工程需要,有必要进行二次开发。以CVMAC和Visual Basic 6.0作为开发工具,开发三维船体结构重量重心及材料统计计算系统,可以处理从CADDS 5中获得的数据,自动完成区段和全船的重量重心及材料统计计算,提高设计效率和计算准确性。

To calculate the mass and gravity center of the vessel according to the designed plane drawings was not only complicated and time-consuming, but also very difficult to assure the accuracy of calculation result. Although it could help the designs with 3D software, it still could not satisfy the requirement of the actual design project. The necessity to carry on secondary development to this software was needed. A system to compute the structural gravity center and the material statistics of three-dimensional hull was developed based on the CVMAC and the Visual Basic 6.0 tools. The system could handle the data acquired from the CADDS 5 as well as calculate both the section data and the whole ship data of the gravity center and materials. The design efficiency and the calculation accuracy could be improved to a great extent with this system.
