Design method of elliptic thin-wall cabin section additive manufacturing model

The invention relates to a design method of an elliptic thin-wall cabin section additive manufacturing model, and belongs to the technical field of thin-wall cabin section additive manufacturing. The invention provides a design method of a model with a multi-layer supporting structure for the challenge of profile control in additive manufacturing and post-processing of an elliptic thin-wall cabin section. Constructing an elliptic thin-wall cabin section model based on simulation analysis software; two cylindrical inner supporting dimensional structures are arranged on the two sides of the center line of the short axis of the inner surface of the oval thin-wall cabin section, and a rib plate is arranged between the cylindrical inner supporting dimensional structures in the direction of the short axis. Carrying out analogue simulation on the elliptic thin-wall cabin section to obtain a model deformation result; through the circle center of the deformation curvature circle at the deformation position, a thin pla
