The casting simulation technology originated in the 1940s. With the support of the American Foundry Association, Professor paschkis of Columbia University used a mainframe computer to analyze the heat flow of the gating system. Then in the early 1960s, forsund, a Danish scholar, theoretically analyzed the solidification process of...
With the increasing maturity of computer technology, casting simulation software tends to be improved. Casting numerical simulation technology has become the third important method to solve actual casting defects after empirical judgment and experimental analysis. Casting CAE technology is more comprehensive and detailed than experimental and theoretical methods. The...
Casting simulation technology first rose abroad in the 1960s. Denmark, the United States, Germany, Japan and other countries have successively carried out research in this field. The simulation direction has gradually developed from the initial solidification process simulation to the later filling process, stress field and microstructure simulation. The...
As we all know, the casting process is an extremely complex high-temperature, dynamic and changing process, and the casting defects such as shrinkage porosity and shrinkage cavity in the solidification process of castings are also difficult to be observed directly. In the past, in order to improve casting defects,...
Casting refers to the process of melting solid metal into liquid, pouring it into a specific shape of mold, and then solidifying it into shape. Metal shrinkage occurs in the following three stages: liquid cooling; Coagulation; Solid cooling. The volume change and pouring temperature cooling change under the shrinkage...
Relevant research in China began in the late 1970s. Although it started late, it developed rapidly. In 1980, Shenyang Foundry Research Institute and Dalian University of technology simulated the temperature field of the casting. Subsequently, according to the actual needs of production, the state arranged scientific and technological research...
Nodular cast iron intercooler base pipe is an innovative design for the company’s large internal combustion engine. The material is QT500-7. It integrates the functions of air inlet and water inlet of diesel engine. It belongs to nodular cast iron with thin-walled box, and its overall dimension is 2154mm...
1. Casting process Adopt the core assembly and vertical pouring process, pre assemble the base core, water jacket core, airway core and end core (as shown in Figure 1), and then add a top cover core. Among them, the base, top cover, front and rear end cores and airway...
In recent years, with the development of casting numerical simulation technology, there are many achievements in the application research of casting process simulation technology, especially in the traditional sand casting and pressure casting. Compared with ordinary sand mold casting and pressure casting, the application of casting process numerical simulation...
Compared with foreign research, domestic research started late, and domestic research on casting numerical simulation technology began in the 1970s. In 1979, with the preparation of the National Foundry Society, the first solidification theory seminar in China was successfully held in Dalian. Since then, many research institutions and colleges...
