1. Determination of casting process plan for BOP shell According to the solidification simulation analysis of the product digital model, combined with the structure of the BOP shell casting, considering the core and forming problems, the casting process plan of the BOP shell casting with the rectangular cavity downward...
The saddle is a key component connecting the suspension and frame. Due to the newly developed saddle being a cast product, its large size, complex structure, and thin wall easily lead to problems such as shrinkage porosity and shrinkage defects during the production process. Casting simulation is a technology...
By analyzing the influence of the solidification mode of molten metal on the quality of sand castings, the solidification front of the layer-by-layer solidification mode is in direct contact with the solution, and the volume shrinkage occurs when the metal changes from liquid to solid, which directly affects the...
Simulating and analyzing the metal flow process during mold filling, the heat transfer phenomenon during mold filling, and the coupling calculation of flow field and temperature field after mold filling are important contents of the numerical simulation of casting process. First of all, by simulating and analyzing the flow...
Although the casting process simulation has made a lot of valuable achievements in the past few decades, some important research is still puzzling researchers.

Many simulation...
The relevant research in China began in the late 1970s, and although it started late, it developed rapidly. In 1980, Shenyang Institute of Needle Manufacturing and Dalian University of Technology conducted temperature field simulation for castings. Subsequently, according to the actual needs of production, the State arranged scientific and...
As early as 1940, when computer technology was just starting, Victor Paschkis of Columbia University of the United States put forward a mathematical model for the analysis of casting process simulation “HeatandMass Flow Analyzer”. Based on this analytical model, Victo Paschkis made a heat conduction analysis on the sand...
