本文提出用面内云纹软版基准栅方法量测计算曲面塑性成形件的应力应变分布,推导并验证了曲面云纹计算公式,解决了有关实验技术问题。并对翻边件变形区和拉延件变形区的曲面成形部位进行云纹解析,得到该塑性曲面成形区应力应变分布的满意结果。
In this paper, the stress-strain distribution of curved plastic forming parts is measured and measured by the soft-plate reference grid method of in-plane moire, the calculation formula of curved moire is deduced and verified, and the related technical problems are solved. And the deformation of the flange and the deformation zone of the deformation of the curved part of the formation of cloud moire resolved to obtain the plastic curved surface of the stress-strain distribution of the satisfactory results.
