中文摘要: |
利用Moldflow分析了吸尘器轴承座的成型过程,通过细化构件的有限元网格和对比网格质量,检验了有限元分
析结果收敛性,确认需要结合网格质量来改进计算过程。构件变形的有限元分析结果与实测数据进行比较,在最大翘曲
的估计方面效果较好,显示了对注塑过程和构件进行精确分析的重要性。文中也尝试采用不同的黏度模型对注塑件翘
曲进行分析,保证分析方法的一致和完整,为基于有限元分析的模具设计和加工过程优化积累经验。 |
英文摘要: |
Moldflow was used to analyze the injection moulding process of a vaccum bearing stand. and we checked the
convergence of the results of finite element analysis was checked by refining mesh and examining the mesh quality, and
mesh quality was confirmed that it was the key for the improvement of computing process. Through comparing finite
element analysis results and measured data. we can obtain confidence in estimating maximum warpage, showing the
importance of accurate analysis. We have also tried using different viscosity models in warpage analysis to accumulate
experience for analysis of the mold design and process optimization based on the finite element analysis. |
