【摘要】 平面闸门是闸门最常见的形式，其设计任务繁重，出图量大。本文根据水工金属结构CAD研究现状，着眼于国内平面闸门的主要结构形式，借鉴了相关CAD系统的开发经验，研制开发了一套平面闸门CAD集成系统(PGCAD系统)。主要研究内容如下： 1、研究探讨了CAD的系统结构；根据平面闸门的设计过程和特点，采用集平面结构设计——有限元建模——施工图绘制——计算说明书生成于一体的设计方法。选用当前流行的VC、VB开发工具混合编程，使系统具有友好的用户界面和高效的计算能力。 2、依据现行的《水利水电工程钢闸门设计规范》、《水电站机电设计手册》，综合相关的钢结构设计原理，研究了平面闸门的结构设计计算方法并研制开发了平面闸门结构设计子系统。 3、根据平面闸门的结构特点，在ANSYS中建立平面钢闸门的几何模型，系统自动生成APDL命令流，部分实现了闸门有限元建模自动化。 4、探讨了平面闸门参数化绘图的程序开发技术，研究建立了水工金属结构图形库，开发了平面闸门布置图绘制子系统，实现了平面闸门布置图的自动绘制。 5、研究了Word软件的VB开发技术，探讨了计算设计报告的自动生成技术，初步实现了平面钢闸门计算说明书自动生成。更多还原

【Abstract】 The plane gate is adopted most widely, whose design is burdensome and heavy. According to the present situation of the CAD research in Hydraulic Metal and the main form of the plane gate, a integrating CAD system is developed by referring to the experience of related CAD system development. The main contents are as follows:1. This paper discusses the structure of CAD system. According to the design process of the plane gate, this paper combines the structure design, special FEM modeling and working drawing and calculation description in PGCAD system. During the programming, Mixed-language programming technology is applied by using the prevalent developing tools such as VB, VC and so on, which makes PGCAD system bear friendly interface and high computation efficiency.2. According to water resources and hydropower engineering specification for design of steel gate, mech-electric design handbook for hydropower station and with the consideration of the related theories on steel structure, this paper studies the design method and calculation theories of the plane gate. On the basis on above, the plain structure design subsystem is developed.3. With the using of the APDL streaming based on ANSYS and according to the specialties of plane gate, the geometry model of plane gate is set up automatically, the modeling work in plane gate FEM analysis is semi-automatic.4. The parameterized method of disposition drawing of the plane gate is discussed in this paper. With the foundation of the establishing of a graph library of Hydraulic Metal, the working drawing subsystem is developed, which realizes the auto-disposition drawing.5. The technology of auto-calculation description is discussed, and the calculation description subsystem is developed based on Word software using VB, so the PGCAD system is more practicable.更多还原
