| The burgeoning new energy vehicle market has heightened the demand for lightweight automotive solutions, propelling the increased integration of cast aluminum alloy components throughout the entire vehicle. The common casting processes of aluminum alloy automotive components are introduced, including sand casting, gravity casting, pressure die casting, low pressure casting, differential pressure casting, and squeeze casting, and a comparison is made from the perspectives of performance, efficiency, quality, cost, and typical applications. New casting technologies such as integrated die casting and sand mold 3D printing casting technology are introduced. A comprehensive review of the development of casting numerical simulation technology from the aspects of mathematical models and numerical calculation methods is provided, summarizing the current research status of mathematical models for flow field, temperature field, stress field, and microstructure, as well as numerical simulation calculation methods for filling and solidification processes. Comparative analysis of mainstream casting forming numerical simulation software is conducted. The mesh generation technology for pre-processing of casting numerical simulation, the setting of thermal physical parameters and boundary conditions, as well as the post-processing module visualization technology and the result verification methods are summarized. The application and new development of casting numerical simulation technology are introduced, including guiding mold design, optimizing process parameters and developing integrated computing platforms and their development and application in new casting technologies are also expounded. Finally, the current issues are analyzed and future research directions are prospected. |
