讨论了纤维缠绕壳体应力平衡系数的定义.在封头与圆筒等强的条件下,给出了应力平衡系数的确定方法.得到了应力平衡系数k_s与圆筒缠绕角α的关系式.结果表明,应力平衡系数随圆筒缠绕角的减小而减小.只要k_s<1,则应力平衡系数的引入,将增加圆筒的质量.为此,适当增大圆筒缠绕角,既能使封头得以加强,又能减小圆筒质量的增加.
討論瞭纖維纏繞殼體應力平衡繫數的定義.在封頭與圓筒等彊的條件下,給齣瞭應力平衡繫數的確定方法.得到瞭應力平衡繫數k_s與圓筒纏繞角α的關繫式.結果錶明,應力平衡繫數隨圓筒纏繞角的減小而減小.隻要k_s<1,則應力平衡繫數的引入,將增加圓筒的質量.為此,適噹增大圓筒纏繞角,既能使封頭得以加彊,又能減小圓筒質量的增加.

The definition of stress equilibrium factor for the filament-wound case is discussed. A method determining the stress equilibrium factor is given when the closure and the cylinder strength are equal. The relationship of the stress equilibrium factor k_s and the cylinder wound angle α Is obtained. The results show that the stress equilibrium factor will be decreased when the cylinder wound angle is decreased. The mass of the cylinder is increased as long as stress equilibrium factor k_s＜1. Therefore, the appropriate increase of the cylinder wound angle will strengthen the closure and reduce the mass increment of the cylinder.
