Beschreibung
Zusammenfassung:	The invention discloses a symmetrical non-rotation composite material inclined grid structure suitable for automatic forming. The symmetrical non-rotation composite material inclined grid structure comprises an upper end frame, a lower end frame and two-way spiral ribs. The upper end frame, the lower end frame and the two-way spiral ribs are of an integrally-formed structure, and structural materials used by the upper end frame, the lower end frame and the two-way spiral ribs are composite materials. The bidirectional spiral rib comprises two mutually symmetrical ribs, and the center line of the outer contour surface of each rib is an equal-pitch spiral line, an equal-spiral-angle spiral line or a geodesic line. The invention further discloses a method for determining the center line of the rib for the typical symmetric non-rotation structure applied to various aerospace engineering. The inclined grid structure is reasonable in design, light in weight and suitable for automatic batch production. 本发明公开了一种适用于自动
