摘　　要：针对管状零部件的展开尺寸计算,根据弯曲成形件在展开后体积不变的原理,推导出一个实用公式,只需输入内径和外径的尺寸,即可得到管状零部件的展开尺寸。For the unfold size calculation of tubular components,a practical formula is derived based on the principle that the volume of the curved forming parts is constant after unfolding.After entering the dimensions of the inner and outer diameters,the unfold size of the tubular component can be obtained.

关 键 词：展开尺寸 中性层半径 体积不变原理 内径 外径
