Three dimensional parameterization modeling method for pressure vessel head
Abstract：To meet the need of pressure vessel design industry and raise the design efficiency of such components as pressure vessel head, cylinder, flange and elbow, UCS was established with VBA programming tool embedded in AutoCAD software and the relative functions were compiled. Through adding the insertion point function and combing the transform technology of spatial coordinate system, three-dimensional modeling for the head was realized with such methods as Boolean operation and rotation. With the proposed parameterization modeling method, 3D head model to meet the requirement can be obtained at arbitrary visual angle and target point only through entering the relevant data of the head by designer. Besides, in combination with AutoCAD 3D modeling technology and VBA programming, the parameterization modeling for other pressure vessel components such as flange and elbow can be performed. The present research can provide a certain reference for exploiting and designing the AutoCAD 3D plug-in in relevant industries.
