Abstract
During the casting process, computer aided design (CAD) and computer aided engineering (CAE) play important roles, but they have been separated from each other. To promote the efficient connection between numerical simulation and casting design, an approach of casting CAD/CAE automatic optimal riser design technology is presented. First, simulate heat transfer and get isolated liquid regions of steel casting without risers. Then, display the isolated liquid regions on Unigraphics and build risers automatically. Finally, use a simple casting to test this CAD/CAE system. The experiment results showed that the designed risers are reasonable. Based on Unigraphics platform and InteCAST software, the casting design (CAD) is combined with the numerical simulation (CAE), and an automatic optimal riser design system for steel casting was developed. It can build three-dimensional risers automatically and provide a proximal optimum design for CAE valuation and even practical producing. This method can shorten the design period and ensure the casting quality.
