以毛竹（Phyllostachys heterocycle）竹筒为研究对象,经测定竹筒直径和壁厚,确定了毛竹壁厚与其直径的关系;建立针对矩形竹片的竹筒剖分数学模型,计算并分析了不同竹筒直径、加工余量、开片数时的矩形竹片截面尺寸、截面积、截面出材率,获得了竹筒开片数的合理取值范围、依据宽度的规格竹片的竹筒最佳开片数,给出了根据竹筒小头直径、加工余量、竹片规格选取竹筒开片数的检索表。结果表明:毛竹壁厚随其直径的增大而线性增大;竹筒开片数增加,竹片厚度增大而宽度减小,开片数较小时变化较明显,开片数较大时变化很小;开片数取8时,可获得最大截面的矩形竹片;竹筒的截面出材率随开片数的增加先增后减...

Taking the bamboo tube as the research object, the relationship between the wall thickness and the diameter of the bamboo tube was determined by measuring the diameter and wall thickness of the bamboo tube. By establishing a mathematical model of lengthwise cutting bamboo tube to prepare rectangle strip, the cross-sectional dimensions, cross-sectional area and cross-sectional outturn rate of rectangular strips with different bamboo tube diameters, processing allowances and number of lengthwise cutting were calculated and analyzed. The reasonable value range for the number of lengthwise cutting...
