Novel reinforcing rib layout design method of thin-wall machine case

The invention discloses a novel reinforcing rib layout design method of a thin-wall machine case. The novel reinforcing rib layout design method is characterized by carrying out reinforcing rib layout design on the outer surface of a conical-surface machine case by utilizing a conical helix, carrying out the reinforcing rib layout design on the outer surface of a machine case of which a conical surface and a cylindrical surface are combined by utilizing a cylindrical helix, the conical helix and a cylindrical helix, controlling the positions of a starting point and an end point of the conical helix on the outer surface of the conical-surface machine case by utilizing a conical helix control rule, controlling the positions of a starting point and an end point of the cylindrical helix on the outer surface of the cylindrical-surface machine case by utilizing a cylindrical helix control rule, and controlling the positions of starting points and end points of the conical helix and the cylindrical helix on the outer surface of the machine case of which the conical surface and the cylindrical surface are combined by utilizing a conical helix and cylindrical helix control rule. The novel reinforcing rib layout design method disclosed by the invention has the advantages that the layout of different reinforcing ribs can be quickly modified, and the novel reinforcing rib layout design method is suitable for the reinforcing rib layout design on the outer surfaces of the conical-surface machine case, the cylindrical-surface machine case and the machine case of which the conical surface and the cylindrical surface are combined.
