This invention belongs to the field of
aerospace technology, specifically disclosing a corrugated plate load-bearing cylinder structure. The cylinder is constructed using corrugated plates, a
skin, and annular fasteners. Due to the inherent thickness of the corrugated plates, the resulting cylinder possesses high
bending stiffness, thus enabling it to bear significant loads. Furthermore, by fixing the inner wall of the
skin to multiple outer ring protrusions of the corrugated plates to form the outer cylinder mounting surface, the connection between each outer ring protrusion of the corrugated plate and the
skin is a planar structure. This results in the corrugated plates and skin forming multiple vertically arranged strip-like surfaces after installation, preventing localized
instability. Compared to conventional cylindrical structures using rod structures or aluminum
alloy skin
stringer structures, this invention improves the structural efficiency of the cylindrical structure.
