本文应用无矩理论,视椭圆球壳为相应的圆球壳经线性变换而成,作用于壳体上任意点处竖向外荷载,被表示成通过该点的子午面与基准子午面所成夹角的三角级数,将推导得出的圆球壳的经线方向法向力、纬线方向法向力、平错力等内力计算式,再换算成椭圆球壳的内力计算式。破坏试验的结果与理论计算吻合良好。 In this paper, the momentless theory is applied. The ellipsoidal shell is transformed into the corresponding spherical shell by linear transformation. It acts on the vertical load at any point on the shell and is expressed as the meridian plane passing through this point and the reference meridian plane. The trigonometric series of included angles will be derived from the normal force in the longitude direction of the spherical shell, the normal forces in the weft direction, the flat force and other internal force calculation formulas, and then converted into the internal force calculation formula of the ellipsoidal shell. The results of the destruction test agree well with the theoretical calculations.
