摘要

本文提出了新的参数,以改善F2MC管作为可调谐减振器的阻尼性能。它们在易受高频振动噪声影响的环境中提供了非常好的性能。这项研究强调了改变F2MC管的一些参数的行为,这是以前从未研究过的。这些参数包括每两个相应层之间的厚度比和管中填充的流体类型。本文通过MATLAB®软件函数求解器求解梁的控制方程和管的应力分析方程,以求得组合系统的响应。为了确保修改的准确性,已经通过执行示例并将结果与文献中现有的数据进行比较来提出验证。结果表明,通过研究厚度比,F2MC管的性能比以前的研究成果提高了20%,在相同条件下,用甘油代替水可以再提高12.82%。最后,在梁的频率响应函数图中,实现了34.34dB的一阶模态振幅降低。

Modifications on F 2 MC tubes as passive tunable vibration absorbers
This paper presents new parameters for damping improvement in F2MC tubes performance as tunable vibration absorbers. They offer very good performance with environments having susceptibility to high frequency vibration noise. This study highlights the behavior of changing some parameters of F2MC tubes which never have been studied before. These parameters include thickness ratio between each two respective layers and fluid type that the tubes are filled with. In this paper the beam governing equations with the tube's stress analyses equations are solved for finding the combined system's response by MATLAB® software function solvers. To ensure accuracy of modifications, validations have been proposed by performing illustrative examples and comparing the results with the existing data available in literature. The results showed improvements of F2MC tubes performance 20% over previous studies achievements by studying the thickness ratio, and another 12.82% can be added by using glycerin instead of water under the same conditions. Finally, the reduction of 34.34 dB in first mode amplitude of vibration was achieved in the beam's frequency response function plot.
