摘要
本文讨论了唐奈尔(Donnell)简化圆柱壳体理论的局限性,放弃了唐奈尔的部分简化假设,考虑了横向剪切力和切向位移的影响,建立了任意长圆柱壳体在一般荷载作用下的修正理论.文章给出两端简支的任意圆柱壳的静力分析和动力响应,得出显式分析解.最后,进行算例计算.
This paper reveals the restrictions of Donnell's simplified theory aboutcircular cylindrical shell,renounces some of Donnell's simplication assump-tions,and takes into account of the influences of the transverse shear forceand tangent displacement,thus establishing a revised theory which wonld beeffective for the circular cylindrical shell of any length under general loadconditions(static or moving loads).This paper also presents a theoreticalanalysis for the static problem and the dynamic response of the thin circularcylindrical shell which is simply supported at both ends and is of any length.The analytical solution is obtained in explicit form.Finally,computed samples are performed.The results show that therevised theory is both precise and applicable to practical uses.
