轧制成形三维形变场的全息干涉法分析

Holographic Interferometry Analysis of 3-dimensions Strain Field in Process of Roll Fornming

叙述了用全息干涉法研究轧制压力成形过程 .运用工艺过程变换法、单张全息图法、多孔窥视板法和条纹漂移等技术 ,分析了成形过程中毛坯侧面三维形变场的特征和分布 。

The process of roll forming is studied by holographic interferometry.Based on the process engineering transformation,single hologram interferometer's method,multi peep door's method and stripe drifting technology,the feature and distribution of 3 dimension deformed field of blank's side in the process of formation is analysised,which has a certain instruction to industry production.
