【摘要】 以2种过渡形式的球面舱壁作为研究对象,利用Riccati传递矩阵法对其结构强度进行计算并分析。研究了锥壳过渡球面舱壁中半锥角和球-环折角对结构强度的影响,建议优先选取较小的球-环折角;讨论了球壳及环壳半径对圆弧过渡球面舱壁的影响规律,认为在一定的球面舱壁长度下,存在特定球壳半径及相应的环壳半径使得应力状态最佳;比较了2种形式的球面舱壁结构,分析其结构强度差异。更多还原

【Abstract】 Studying on two kinds of spherical bulkheads with different structural style, the paper is concerned with strength analysis for them using Riccati transfer matrix method. The influences of semi-cone angle and curved angle in sphere-cone on the stress strength of spherical bulkhead with conical transition are discussed. The less curved angle in sphere-cone is suggested in priority. The influences of radius of sphere and toroid on the stress strength of spherical bulkhead with toroidal transition are also researched. In the condition of a fixed length of spherical bulkhead, it exist a certain radius of sphere and corresponding radius of toroid that make the stresses state better. Also, the comparisons of two kinds of spherical bulkhead in structural strength are given.更多还原
