摘要
为考虑活塞桁架与底板之间的剪切作用,本文将容器活塞底板视为部份环形板处理,设活塞桁架作用在底板上的剪力按幂级数规律分布,将问题归结为部份环板的合边值问题。文中导出了这一弹性力学平面问题的解答,给出了底板径向位移的一般表达式,并对底板与桁架下弦各节点以及中心筒壳处的位移协调条件进行了分析。
Taking aecount of shear action between the piston truss the bottom plate, this paper assumes the bottom plate to be a part-ring and supposes that the shear distribution follows the power series law, making the problem to be a problem of mixed boundary condition of part plate. In the paper, the solution of this elastic plane problem is derived. The general expressions of radial displacement of bottom plate are given. The compatible conditions both at the nodes of the lower chord of the truss and at the central cylindrical shell are analyzed.
