Abstract: Aiming at the problem that the docking assembly task of thinwalled cylinder sections with different sizes, an automatic flexible clamping device based on multimechanical cooperative working mode was developed, which was applied to the field of thinwalled tubular section structure automation docking assembly, realized fast and reliable clamping of any cylindrical or irregular shape thinwalled tubular section structure with the diameter of the tool hole in the range of 400 mm~1156 mm, the docking assembly quality and working efficiency of the thinwalled tubular section structure were significantly improved. Then limit location statics simulation of the two extreme working positions of the flexible clamping device was completed based on ANSYS Workbench. The results indicate that each component is reasonable. It can be applied to aerospace vehicle automation flexible assembly line.

Key words: thinwalled tubular section structure; docking assembly; flexible clamping; finite element simulation
