The invention relates to the field of integral manufacturing of large storage tanks for spaceflight, and particularly discloses a method for establishing spinning tire molded surface compensation based on a section curve and a thickness function. The method comprises the following steps: deducing and establishing a cross section target curve of a spinning tire according to a cross section curve of an ultra-large-diameter storage tank bottom and working allowances of the top and the bottom of a storage tank bottom spinning part; the machining allowance of any position of the spinning part is determined by conducting linear processing along the arc length of the part section inner edge face curve according to the machining allowance of the top and the bottom, and a model tire target section curve is solved according to the geometrical relationship between the part section inner surface curve and a model tire target section curve part. 本申请涉及航天用大型贮箱整体化制造领域，具体公开了一种基于截面曲线和厚度函数建立旋压胎型面补偿方法。本发明根据超大直径贮箱箱底的截面曲线以及贮箱箱底旋压件
