摘要

变形是金属铸造部件生产中的一个突出问题,尤其是在使用金属模具时。现有研究强调,凝固部件从模具中取出时的温度对部件的最终变形起着关键作用。这项数值研究通过模拟实验条件,力求全面了解影响变形的因素。研究利用商业软件 "Abaqus "对不同的脱模温度进行热力学耦合模拟。对变形的时间演变进行了研究,重点是弹性应变和热应变等影响因素。对模拟结果和实验结果进行了定量和定性比较。实验结果和模拟结果之间的差异随着脱模温度的升高而呈线性增长。讨论了利用实验和模拟结果之间的定性相似性作为开发变形控制策略基础的可能性。

Numerical Analysis of the Influence of Demolding Temperature on Final Distortion in Gravity Die Casting Process

Distortion can be a prominent issue in the production of metal casting components, especially when using metal dies. Existing research underscores the pivotal role of the temperature at which the solidified component is extracted from the mold in contribution to the ultimate distortion of the component. This numerical investigation seeks a comprehensive understanding of the factors governing deformation by employing simulations that emulate experimental conditions. The study utilizes coupled thermomechanical simulations, executed through the commercial software “Abaqus,” across varying demolding temperatures. The temporal evolution of distortion is examined, with a focus on influential factors such as elastic and thermal strain. A quantitative and qualitative comparison is drawn between simulation outcomes and experimental results. The difference between experimental and simulation results was observed to increase linearly with higher demolding temperatures. The potential for leveraging the qualitative similarity between experimental and simulation results as a foundation for the development of distortion control strategies is deliberated.

期刊介绍: The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
