基于AutoCAD与VB的船闸下闸首建模

Modeling of the Lower Lock Head of Ship Lock Based on AutoCAD and VB

依靠Visual Basic自身所提供的强大的图形编辑功能,在界面空间实现结构形体的可视化。选择AutoCAD为图形系统,选择AutoCAD的DXF(Drawing exchange File)文件作为图形数据交换文件来解决AutoCAD与Visual Basic之间的图形数据交换,并利用ActiveX Automation技术来实现AutoCAD与Visual Basic之间的相互沟通。在ANSYS中建模非常费时费力,选择AutoCAD与VB的联合编程实现了船闸下闸首的参数化造型而后导入ANSYS的方法。这大大缩短了研究进程,也为类似问题的研究提供了有效的参考途径。

Depend on powerful function of graphic editing which Visual Basic provides itself, the space structure can be visible in interface space. AutoCAD can be chosen as the graph system and the document DXF of AutoCAD is chosen as the graphic data exchange file in order to solve the graphic data exchange between AutoCAD and the Visual Basic. Besides, the mutual communication between AutoCAD and the Visual Basic can be achieved through the technology of ActiveX Automation. The modeling is very difficult and time-consuming in ANSYS. In this paper, the combination of AutoCAD and VB was used to establish the parameterized molding of the Lower Lock Head of navigation lock and then ANSYS was introduced. This can greatly reduce the research process and provide effective reference for similar research.
