The invention discloses a wide-band automatic laying and winding near-net forming method for a large convex-concave curved surface fusion special-shaped cabin, and belongs to the field of composite material structure design and forming processes. The invention particularly relates to a laying and forming process method for various complex skin structural members such as spatial axial symmetry, plane symmetry, non-axial symmetry, special-shaped convex-concave curved surfaces and the like through circulating laying and winding, reciprocating laying and winding, overlapping laying and winding and the like of a series of heat-proof and heat-insulation composite material fiber gridding cloth belts. The method mainly comprises a series of key generality technologies of respectively laying two different shapes of convex-concave curved surface fusion special-shaped cabins by adopting two resins with different viscosities, and designing and optimizing a near-net laying track of the large convex-concave curved surface fusion special-shaped cabin. The seven-axis RTCP optimization control thought and the implementation method of acceleration and deceleration disturbance control based on speed optimization are characterized in that the seven-axis RTCP optimization control thought and the implementation method are based on a grid curved surface trajectory planning and spiral line surface intersection method trajectory generation and post-processing technology, control over laying and winding key technical parameters such as the optimal cloth belt broadband and the overlapping amount of reciprocating circulation laying and winding.
