Abstract：

Aiming at the problem that the dispersion angle of the depression point was not clear when the dispersion trajectory of the depression point was used to process the plate, the quality of the plate formed by the dispersion trajectory of the depression point was analyzed at the dispersion angle of 2°, 5° and 10° respectively, and the forming process of the plate was analyzed by finite element analysis software ANSYS and post-processing software LS-PrePost. The results show that the minimum thickness values of the plate formed under the dispersion trajectory of the depression point at dispersion angles of 2°, 5° and 10° are approximately equal, and the thinnest thickness of the plate is located in the bottom forming area. Among them, the surface quality of the plate after forming is the worst under the dispersion trajectory of depression point with dispersion angle of 2°, followed by that with dispersion angle of 5°, and the best with dispersion angle of 10°. In addition, finite element analysis and forming experiments show that when the dispersion angle is 2°, the maximum value and average value of the Z-direction deviation of the formed plate are the largest, and the contour accuracy is the lowest. For dispersion angle of 5°, the maximum value and average value of the Z-direction deviation are both in the middle, and the contour accuracy is also in the middle. For dispersion angle of 10°, the maximum value and average value of the Z-direction deviation are the smallest, and the contour accuracy is the highest.
