3D Parameterized Modeling And Database Management System Designing Of The Solid State Relay CAD

The challenge of new industry revolution before us makes it important to develop and popularize CAD technology, especially in electric apparatus field. Electric apparatus CAD is one of the most important application of computer science and information technology. At the same time, 3D modeling and database are more and more popular in CAD.A new 3D parameterized modeling and database management system of the solid state relay CAD is introduced in this paper. The User can build parts of the solid state relays rapidly and easily by the parameters and the database. In addition, they can be managed conveniently. An interface program to ANSYS is made to convenient the user' work of the finite element analysis.This thesis illustrates the technologies and the methods of CAD software, including software engineering, database designing, CAD software platform, development tools etc. At last, the setup program, help files and user's guide files are introduced.
