【摘要】 本文将活塞桁架对中心圆筒的作用等效为均布线荷载,将中心圆筒作为闭合圆柱壳、圆板,环板的弯曲和弹性力学平面问题的组合结构问题处理,给山了其内力和位移的解析解及数值算例,结果具有较大的工程应用价值.更多还原

【Abstract】 In this paper, the action of piston truss to central cylinder is simplified as uniformly distributed linear load, the central cylinder is treated as a builtup construction problem which includes a closed cylindrical shell, a circular plate and a ring plate, which consider their bending problem and mechanics of elasticity plane problem. The analytic solutions of internal forces and displcements are provided. It also gives a numerical example. The results of this paper are valuable in engineering practice.更多还原
