Abstract:

Finite element model was proposed to simulate the flexible roll forming process. Based on theoretical analysis of bending process, the longitudinal curvature equations of the formed part was set up. The method to design maximum height difference and the compression ratio difference in the cross-section was given. Numerical simulation was carried out, and the simulation results are in good agreement with the theoretical values. A small experimental device was developed and flexible roll forming tests were carried out. The results demonstrate that flexible roll forming can be used for forming three-dimensional surface parts efficiently.

Key words: material synthesis and processing technology, three-dimensional surface, rolling, flexible roll
