摘要
利用网格理论和微分几何学分析了纵向平面缠绕规律，讨论了主曲率与缠绕角的关系，系统地推导出了纵向平面缠绕壳体的优化结构曲线的微分方程及其数值解的递推公式和缠绕角公式。
The winding laws of longitudinal plane are analyzed by using network theory and differential geometry. The relation between main curvature and winding angle is discussed. The recurrence formulae for differential equations and their numerical solutions of the optimum construction curve are derived. The formulae for the windinal direction plane in a systematic way are obtained on the basis of network theory and differential geometry.
