一、前言随着科学技术的发展,特别是宇航技术的发展,对结构形式提出了新的要求,研究某种轻质高刚度的新型结构,正是为了满足这一需求。波纹形圆柱壳是一种重量轻轴向刚度大的新型结构,其特点是结构效率高,主要体现在轴向波纹条均构成加劲杆,因而,主要应用于抗轴压屈曲结构中,抗曲刚度主要由波纹肋条提供。这种异型结构元件的轴压屈曲载荷由于上述之特点而提高许多,它的重量比光壳结构(承受同样载荷时)
I. INTRODUCTION With the development of science and technology, especially the development of aerospace technology, new requirements have been put forward on structural forms. It is precisely for this purpose that a new type of structure with light weight and high rigidity is studied. Corrugated cylindrical shell is a new type of light weight and high axial stiffness, which is characterized by high structural efficiency, which is mainly embodied in the axial corrugated stiffener. Therefore, it is mainly used in anti-axial buckling structure, anti-flex Stiffness is mainly provided by corrugated ribs. The axial compression buckling load of such a profiled structural element is much higher due to the above-mentioned characteristics, and its weight is smaller than that of a light-shell structure (when subjected to the same load)
