The invention discloses a curved surface fitting drum design method and a curved surface fitting drum. The method comprises the following steps: determining a pre-stretching rate based on a preset stretching characteristic curve graph of a 0-degree reinforced cord fabric layer; determining the radius of the curved surface fitting drum based on the material thickness and the radius of a 0-degree reinforced cord fabric layer in the tire structure of the tire, wherein the material thickness is the material thickness between the 0-degree reinforced cord fabric layer and the curved surface fitting drum; generating the curve fitting drum on the basis of the radius of the curved surface fitting drum and the pre-stretching rate, so that the 0-degree reinforced cord fabric layer is located in a material stretching area of the preset stretching characteristic curve graph, the tension of the reinforced cord fabric layer is controlled through the curved surface fitting drum, and therefore the problem that a tire crown assembly is uneven in stress is solved.
