市场:造船精度控制和安装预测模拟系统



摘要
萨明信息系统公司为亚洲造船业提供尺寸精度控制和安装预测模拟系统。为了在市场上率先推出符合亚洲造船标准的三维精度控制系统,萨明需要寻找三维建模技术来开发绘图模块。
通过实施 3D ACIS Modeler、3D InterOp 和 HOOPS Visualize,萨明率先推出了符合亚洲造船市场高标准的 3D 精度控制系统。

Spatial’s components enabled us to be first to market in the highly competitive Asian shipbuilding market. In turn we’ve enabled our customers to accelerate their product development plans and reduce costs at the same time. And also at the shipyards existing workers can provide high quality education to new workers with 3D models using our EcoSystem. It makes it easy to educate the new workers and they can understand fast what they are going to do. It’s really one of the necessary unctions to have to go to the next generation of shipbuilding.
公司
SAMIN Information System 总部位于韩国,为韩国和中国的主要造船厂提供精度控制和安装模拟系统。该公司还在日本、越南、土耳其和印度销售其产品。SAMIN 的客户包括亚洲最大的造船公司:韩国的 STX 造船海洋株式会社、上海外高桥造船有限公司、中国的大连船舶重工有限责任公司和越南的下龙造船有限公司。SAMIN 的产品系列包括用于造船生产的 EcoMES、EcoBLOCK 和 EcoOTS,以及用于造船设计的 EcoVIEWER 和 EcoPINJIG。
SAMIN 的 EcoBLOCK 是基于三维的分块精度控制系统,可与 AVEVA MARINE、Tribon、CADDS、ERSPD、ShipConstructor 和 AutoCAD 等造船三维 CAD 系统连接。通过使用 EcoMES 和全站仪,可对生产中的块(由不同尺寸和形状的钢板和型材组成)进行以下测量
精确测量,并与三维 CAD 系统创建的导入设计模型进行比较,从而轻松准确地分析出任何误差。利用 EcoBLOCK 的分析输出结果,可为任何需要通过切割和翻转进行修正的砌块推导出修正方法。输出结果可用于生产精确满足船东要求的木块。

挑战
寻找强大的三维建模内核
为了率先推出符合亚洲造船标准的三维精度控制系统,SAMIN 需要寻找三维建模技术来开发绘图模块,并从 Tribon 提取三维设计信息(几何、属性)。在寻找组件解决方案之前,该公司一直在进行内部开发工作。

解决方案
SAMIN 通过《使用 ACIS 进行 3D 建模》一书发现了 Spatial 公司。在考虑了 Parasolid 内核之后,2007 年初,SAMIN 决定 Spatial 的 ACIS 3D 建模内核和 HOOPS 应用程序框架将是其 3D 精度控制系统的最佳解决方案。
选择 ACIS 的一个主要因素是基于 ACIS 的造船应用非常普遍。亚洲的造船厂使用专门为建造大型复杂船舶和近海船只而开发的设计系统。这些三维设计程序通常基于 Spatial 的 ACIS 内核,这在很大程度上影响了 SAMIN 购买 ACIS 的决定。使用 ACIS 可确保 EcoBLOCK 和 EcoOTS 与所有领先的造船 CAD 系统相互协作,能够利用所有船舶组件术语,如管道、面板、结构的名称以及测量数据本身。
利用 ACIS 开发 SAMIN 精确度控制系统的另一个主要考虑因素是其交叉功能,该功能可在装配过程中检测船块的干扰。此外,ACIS 还可根据 Tribon(用于设计商业和海军舰船的 3D CAD 系统)的几何数据,帮助构建船块的 3D 实体模型。
HOOPS 的开放式架构和强大的图形功能使 SAMIN 能够快速开发和维护其高性能三维可视化应用程序。该公司特别发现,HOOPS 的参考应用源代码大大加快了开发进程。



结果
通过将 Spatial 的三维建模内核纳入其精度控制系统,萨明能够快速开发其软件并率先推向市场,满足造船业的特殊需求。客户的反响非常积极,认为萨明的技术具有突破性,使造船商能够以更少的劳动力更快地建造船舶,从而降低成本。
目前,萨明在其软件产品中使用了约 40% 的 ACIS 功能,并计划在未来的版本中纳入更多 ACIS 的强大功能。
重要见解
解决方案
SAMIN 认为这些Spatial功能是其软件取得成功不可或缺的因素:
