【摘要】 本文采用类似于扁壳理论的方法,处理了圆柱壳轴对称缓变几何缺陷对其弯曲的影响,并建立了具有轴对称缓变几何缺陷圆柱壳的自由振动微分方程。而后,对两端简支的缺陷圆柱壳的自然频率进行了计算和分析。更多还原

【Abstract】 In this paper, by means of a method similar to the theory of shallow shells, the effct of slow-vcried geometric imperfections on the bend of cylindrical shell have been dealt with. And some equations of free vibration of imperfect cylindrical shell have been obtained. Then, the natural frequencies of imperfect cylindrical shell that is simply surported are calculated and analysed.更多还原
