在对显式动力学有限元方法的概念、基本理论和应用范围进行了阐述的基础上,通过ABAQUS有限元仿真软件,在Explict显式动力学模块中,对4047铝药芯焊丝轧制过程中4047铝带成型过程进行了模拟仿真。比较不同铝带速度下铝带成型质量。比较不同质量缩放因子下仿真结果稳定的4047铝合金的成型质量,择优选出成型质量最好、运算速度最快的质量缩放因子。比较不同上下轧辊轴线距离时4047铝合金成型质量,得出了当上下轧辊的距离为4047铝带厚度时其成型质量最佳。
Based on the concept, basic theory and application range of the explicit dynamic finite element method, through the ABAQUS finite element simulation software, in Explict explicit dynamic module, the 4047 aluminum flux cored wire rolling process 4047 aluminum strip molding process simulation. Compare the quality of aluminum strip with different strip speed. Comparing the forming quality of the 4047 aluminum alloy with stable simulation results under different mass scaling factors, the quality scaling factor with the best molding quality and the fastest operation speed is selected. Comparing the forming quality of 4047 aluminum alloy with different upper and lower roll axis distance, it is concluded that the forming quality is the best when the distance between upper and lower roll is 4047 aluminum strip.
