解，利用翘曲测试数据建立起用于预测轴承座翘曲值的多元回归方程，然后对回归方程进行显著性检验。最后根据回归

| 英文摘要: |
| The finite element model of a bearing stand was processed by Hypermesh to improve the mesh quality and
examined in accordance with the general guidelines of the mesh quality. Four factors and five levels of orthogonal
experiment were used to analyze the relationship between the warpage and each factor in the injection molding process
with Moldflow. With the range analysis,we could obtain the best combination of process parameters for minimum
warpage. To find out the optimal process parameters within the solution space,the regression equation for predicting
warpage was established,and the significance test was made. Finally,the minimum warpage was obtained through the
optimal process parameters from the regression equation. The results showed that high-quality mesh was more easier to be
obtained by Hypermesh rather than Moldflow,and mimmum warpage based on the regression equation was better than
warpage obtained by range analysis. |
