摘要

．本文考虑了非均匀杆加筋的非均匀各向异性接触流体圆柱壳的自由振动问题。Hamilton-Ostogradsky变分原理被用来解决这个问题。人们普遍认为，用于强化的棒材的非均匀性按指数规律变化。圆柱壳的非均匀性沿厚度方向呈线性变化规律。这种液体被认为是理想的。考虑了杆与圆柱壳之间的刚性接触条件。利用接触条件构造了频率方程，用数值方法求解了频率方程的根，建立了特征曲线。

Free vibrations of a nonhomogeneous rod-cylindrical shell-fluid system

. In the present paper, we consider free vibrations of an inhomogeneous anisotropic, fluid-contacting cylindrical shell stiffened with inhomogeneous rods. The Hamilton-Ostogradsky variational principle was used when solving the problem. It was accepted that the nonho-mogeneity of rods used in the strengthening change by the exponential law. The nonhomogenity of the cylindrical shell change by the linear law in the direction of the thickness. The fluid was accepted as ideal. Rigid contact condition between the rods and the cylindrical shell was considered. Using the contact conditions, the frequency equation was structured, the roots were found implemented by the numerical method, characteristical curves were built.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
