摘　　要：给出一端固定,一端自由,自由端有刚性环加强的圆柱壳体的内力和位移的计算公式,以及最大应力的计算公式。对所得公式简化处理,用简单的无矩理论的解来表示复杂的有矩理论的解,使之便于工程计算。本文采用工程壳体理论,对于薄壳,文中给出的解具有足够的精确度。In this paper a ladeg cylindrical shell with one end fixed and another free which is reinforced by a rigid ring, was investingated and formula for determining the free end were presented. These somewhat complicated formula obtained form the bending theory were simplified with the help of the membrane theory so as to facilitate their application to engineering calculation. In the investigation the engineering theory of shells is used. As far as the thin shells usually adopted are concerned, the accuracy of the solutions presented in this paper are sufficiently high.
