Numerical Simulation of Casting Temperature and Stress Fields via the Finite Element Method
摘要
Abstract
To address the national strategic demand for self-reliant industrial software,a unified-mesh-based one-way thermomechanical coupling algorithm was proposed,and dedicated finite element simulation software for casting temperature-stress analysis was independently developed,providing a reliable numerical tool for process optimization.Through air-cooling simulations of a stepped test block,comparative results with ANSYS demonstrate a maximum relative error of 0.789％with consistent cooling trends,validating the high accuracy of the temperature module.Numerical simulation of a grid-shaped stress framework reveals deformation behavior,stress-strain distributions,and hot tearing tendencies during solidification,confirming the correctness of the thermomechanical coupling algorithm and mechanical boundary model.For a combustion chamber shell casting case,the predicted hot tearing defects match actual cast products,confirming the software's industrial applicability for optimizing practical large-scale casting processes.关键词
