本文提出了铁路车辆车体侧围结构中常见的曲薄板的面内和面外耦合振动的分析方法。为了简单处理这种耦合振动，本文提出了一种由直梁和曲梁组合而成的结构。本文叙述了推导运动方程的解析过程。计算结果表明，直曲梁耦合体系能较好地反映顶底板相对竖向位移与边板侧向变形的耦合作用。讨论了悬臂梁和边梁的侧向变形以及曲梁的曲率对受迫响应的影响。
This paper presents an analytical method for in-plane and out-of-plane coupled vibration in thin curved panels which are commonly seen in the side structure of railway vehicle carbodies. To treat such coupled vibrations simply, a structure consist of combination of straight and curved beams is introduced. The analytical procedure to derive the equation of motion is described in this paper. Numerical result shows that the straight and curved beam coupled system (SCBS) can successfully express the coupling effect between roof-floor relative vertical displacement and side panel’s lateral deformation. The effect of lateral deformation of cantrail and side beam and curvature of the curved beams on the forced response are discussed.
