摘要

为研究由内部空心弹性圆柱体和环形肋条支撑的夹层壳体的气动弹性稳定性，考虑了一个很有前途的数学模型。利用推导出的关系，研究了内空心圆柱体的厚度、壳体的长度和夹芯的剪切模量对导致发生扑翼的临界气流速度的影响。根据计算结果，提出了选择夹层复合结构参数的建议。所提出的数学模型使夹层结构壳体气动弹性稳定性领域可解决的专题科学和应用问题的范围得以扩大。

Flutter of a Sandwich Shell with Inner Cylinder and Annular Ribs

A promising mathematical model is considered for studying the aeroelastic stability of sandwich shells supported by an internal hollow elastic cylinder and annular ribs. Using the relations derived, the influence of thickness of the inner hollow cylinder, the length of the shell, and the shear modulus of core on the critical air flow speed leading to the occurrence of flutter was studied. Based on the calculations performed, recommendations were developed for choosing parameters of the sandwich composite structure considered. The mathematical model presented makes it possible to expand the range of topical scientific and applied problems that can be solved in the field of aeroelastic stability of sandwich shells.
