摘　　要： 参考其它行业中翘曲度的应用,引入了评价注塑制品翘曲变形的翘曲度概念。随后对特征尺寸上的翘曲度、平面上特征的翘曲度进行了详细的阐述,并在构建注塑CAE翘曲变形模拟结果的数据结构基础上,提出了基于注塑CAE翘曲变形模拟结果的翘曲度计算方法。用一实例说明了用平面特征上的翘曲度评价翘曲变形的有效性。 Warpage is one of the most important quality indicators of injection-molded parts, and it is necessary to evaluate the warpage to value quality of injection-molded parts. This study represented a definition of warpage degree on some supposed features to describe the warpage of injection-molded parts. The warpagedegrees on the feature dimension, and feature on plane were discussed, and it is also formulated how to evaluate these warpage degrees based on injection molding CAE. Finally, an example was given to demonstrate that the proposed method is correct and effective.
