Flat Steel Gate Parametric Design Cad Software Research And Development,

In this paper, the author bases on the theories and methods of gate design, which is provided by Hydraulic and hydroelectric Engineering Specification for Design of Steel Gate (SL74-95, thereinafter for short Specification) and steel structure for water conservancy (thereinafter for short Handbook), combined with computer aided Structure Design with Parameters about flat steel gate. The author develops wi th VBA at AutoCAD2004 platform and develops CADsystem (Plane Steel Gate Computer Aided Design--PSGCAD system) about planesteel gate. It directly calls the commands of AutoCAD . It works in with AutoCAD to make designers raise their work efficiency.Such mostly contents are as follows:1, The theory of parametric design technology is studied in this paper. A model of parametric subsystem is built. Based on the model, the key technologies-parametric model and parametric driving mechanism of realizing the system are outlined;the method of realizing the technologies is provided at last.2, Basis for theories of flat steel gate design, module system and key technique of system design in PSGCAD system is expounded. The process of flat steel gate design is introduced in PSGCAD system.3, CAD and VBA tool of exploitation is introduced. Design methods and thoughts, which are used in structural dispose and components' sections and procedure development, are expounded in PSGCAD system. Interface design is in PSGCAD.4, Principles and exploitive thoughts in programs of structural drawings and disposal general drawings of gate-leaf are expounded in PSGCAD system.
