在蒙皮体的各种破坏形式中,整体剪切屈曲破坏是具有控制作用的破坏形式之一。采用目前国内常用的YX20-166-830型压型钢板组成的6个蒙皮板进行了抗剪试验研究,它们的边界连接形式分别采取波谷单螺栓连接、波峰单螺栓连接、波谷双螺栓连接、波谷双螺栓波峰单螺栓连接、固支连接和沿波谷两点焊接,给出了边界连接形式对蒙皮板的破坏过程、荷载位移曲线、屈曲形式、屈曲荷载、剪切刚度以及应变分布的影响,从而为蒙皮板强度的确定提供参考依据。 Among the various forms of failure of the skin body, the total shear buckling damage is one of the forms of control that has been ruptured. Shear tests are carried out on six skin panels made of YX20-166-830 profiled steel plate currently used in China. Their boundary connection forms are single-trough, single-trough, trough and two- The influence of the boundary connection on the failure process, load displacement curve, buckling mode, buckling load, shear stiffness and strain distribution of the corrugated double-bolt crest and single-bolt connection, , So as to provide a reference for the determination of skin strength.
