Computer Aided Optimization Design System for Pressure Vessel Housing

The pressure vessel shell computer-aided design system solves the CAD optimization design of the pressure vessel shell, enables the design of the shell according to the needs of the designer, the surface development, the optimization of the discharge and the database management of the welding process card.

The system accepts the user's basic design requirements in a variety of ways, through the human-computer interaction to complete the appearance of the pressure vessel shell, blanking, realistic display, shell surface development, optimization of the discharge and welding process and other auxiliary management, on the computer Shows optimized marker graphs, which can be optimized by the plotter or printer output. The entire system is under WINDOWS 98/NT environment on 586 microcomputer. Using object-oriented programming language Visual C++ programming and development.

Technical indicators and functions:

1. Three-dimensional geometric modeling model of pressure vessel shell

How to represent the three-dimensional geometric shape of the pressure vessel shell inside the computer, the geometric model of the shape is the primary problem of this module. The system uses the GSG tree and boundary representation hybrid model to fully express the characteristics of the object. The outline constructs basic voxels, view transformations, storage management and other functions. The efficient and reliable voxel merging algorithm is used to complete the three-dimensional geometric modeling of the pressure vessel shell appearance.

2. 3D wireframe blanking map generation and display module

The 3D wireframe blanking of the pressure vessel shell is accomplished by using the concepts of related surfaces and related edges, and efficient and reliable hidden line elimination algorithms that reduce the division of the sub-line segments and the visibility of the sub-line segments.

3. Realistic image rendering and display module
