Abstract

In this study, a coupling model of fluid-conveying pipes made of functionally graded materials (FGMs) with NiTiNOL-steel (NiTi-ST) for vibration absorption is investigated. The vibration responses of the FGM fluid-conveying pipe with NiTi-ST are studied by the Galerkin truncation method (GTM) and harmonic balance method (HBM). The harmonic balance solutions and the numerical results are consistent. Also, the linearized stability of the structure is determined. The effects of the structure parameters on the absorption performance are also studied. The results show that the NiTi-ST is an effective means of vibration absorption. Furthermore, in studying the effect of the NiTi-ST, a closed detached response (CDR) is first observed. It is noteworthy that the CDR may dramatically change the vibration amplitude and that the parameters of the NiTi-ST may determine the emergence or disappearance of the CDR. This vibration absorption device can be extended to offer more general vibration control in engineering applications.

NiTiNOL钢丝绳控制FGM流体输送管道振动的新方法

在本研究中，研究了由功能梯度材料（FGM）制成的流体输送管与NiTiNOL钢（NiTi ST）的振动吸收耦合模型。采用伽辽金截断法（GTM）和谐波平衡法（HBM）研究了含NiTi ST的FGM流体输送管的振动响应。谐波平衡解和数值结果是一致的。此外，还确定了结构的线性化稳定性。还研究了结构参数对吸收性能的影响。结果表明，NiTi ST是一种有效的减振手段。此外，在研究NiTi ST的作用时，首次观察到闭合分离反应（CDR）。值得注意的是，CDR可以显著地改变振动幅度，并且NiTi ST的参数可以决定CDR的出现或消失。这种减振装置可以扩展到工程应用中提供更通用的振动控制。

期刊介绍： Applied Mathematics and Mechanics is the English version of a journal on applied mathematics and mechanics published in the People''s Republic of China. Our Editorial Committee, headed by Professor Chien Weizang, Ph.D., President of Shanghai University, consists of scientists in the fields of applied mathematics and mechanics from all over China. Founded by Professor Chien Weizang in 1980, Applied Mathematics and Mechanics became a bimonthly in 1981 and then a monthly in 1985. It is a comprehensive journal presenting original research papers on mechanics, mathematical methods and modeling in mechanics as well as applied mathematics relevant to neoteric mechanics.
