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.

    本发明公开了一种曲面贴合鼓设计方法及曲面贴合鼓,该方法包括:基于所述0°增强帘布层的预设拉伸特性曲线图确定预伸张率;基于材料厚度及所述轮胎的轮胎结构中的0°增强帘布层的半径确定所述曲面贴合鼓的半径,所述材料厚度为所述0°增强帘布层与所述曲面贴合鼓之间的材料厚度;基于所述曲面贴合鼓的半径及所述预伸张率生成所述曲线贴合鼓,以使所述0°增强帘布层处于所述预设拉伸特性曲线图的材料伸张区域,通过曲面贴合鼓控制增强帘布层的张力,从而解决轮胎胎冠组件受力不均匀的问题。
