摘要:

本文针对铝蜂窝扩胞CAE模型参数标定场景中,因变形模式难以被量化而导致的试错法流程效率低下问题,提出一种基于塑性应变云图视觉的变形模式判据。将新方法与传统的刚度特性判据相结合,使用python开发了自动化脚本,在ACMDB壁障铝蜂窝扩胞CAE模型参数标定中开展了应用研究。结果显示,本文提出的变形模式判据与铝蜂窝压溃变形模式相关性较好,开发的自动化脚本可有效降低参数标定过程对工程师的依赖。

Abstract:

To promote the aluminum honeycomb cell scaling CAE model calibration efficiency, which is mainly affected by the difficulty of deformation mode recognition, the plastic strain contour plot vision based deformation mode criterion is proposed in this paper. The new method, along with the traditional stiffness criterion, is integrated into an automated script by python, which is applied in the ACMDB aluminum honeycomb cell scaling CAE model calibration process. The results show that the proposed deformation mode criterion is highly correlated with the aluminum honeycomb compression deformation mode, and the developed automated script can effectively reduce the dependence of the calibration process on engineers.
