摘要
基于能量法推导出了加筋板中薄壁骨材承受轴向周期载荷时的侧倾动力不稳定区的求解方法 .通过和有关文献的结果比较 ,证明该方法是简单、方便可靠的 .
The paper based on the energy method derives a method for solving the dynamic tripping buckling problem of thin walled stiffeners in stiffened plate under periodic dynamic loading. The results were compared with those from other references. It is shown that the method presented in this paper is good and reliable in application. The influences of some parameters, such as the length of the stiffener and static load component, on the dynamic instability region have been discussed.
