Numerical Simulation and Experiment of Flexible Floating Clamping in Multi-roll Stretch Forming Process
摘要
Abstract
The multi-roll stretch forming process of saddle-shaped surface parts with flexible floating clamping mode were simulated by ANSYS/LS - DYNA. The effect of flexible floating clamping mode was verified. The distribution of stress and strain of formed parts was analyzed. Results indicated that the flexible floating clamping mode was suitable for the process of the multi-roll stretch forming process. The stress and strain of the formed part distributed uniformly. Finally, the corresponding experiment was accomplished. When comparing the results of the numerical simulation and that of the experiment, it was concluded that the two types of results were nearly consistent.关键词
