流固耦合管路系统广泛应用于各种装备中, 通常用来传递物质和能量或者动量. 由于流固耦合效应, 管壁在流体作用下易产生强烈的振动与噪声, 对装备安全性、隐蔽性产生严重影响, 甚至造成严重破坏. 流固耦合管路振动抑制需求迫切, 意义重大. 声子晶体可以利用其带隙特性抑制特定频率范围内弹性波的传播, 在减振降噪领域具有广泛的应用前景. 本文基于声子晶体理论, 研究了流固耦合条件下的布拉格声子晶体管路冲击振动传递特性. 将传递矩阵法和有限元法相结合, 计算了能带结构与带隙特性, 重点考虑了流固耦合效应下, 不同冲击激励条件下声子晶体管路振动特性, 分析了流固耦合对声子晶体管路振动传递特性的影响. 研究结果为流固耦合条件下管路系统的振动控制提供了技术参考.
Fluid-structure interaction pipeline systems are extensively adopted to transfer matter, energy and momentum, which are widely used in various fields. Due to the fluid-structure interaction effect, the pipe wall proves to produce strong vibration and noise under fluid action, which has a serious influence on the safety and concealment of the equipment, even leading to serious damages. Therefore, it is of great significance to study the vibration characteristics of fluid-structure interaction pipeline and methods to reduce the vibration of pipeline both in theory and in practice. Phononic crystal can suppress the propagation of elastic waves in a specific frequency range by their special band-gap characteristics, which have wide application prospects in the field of vibration and noise reduction. Especially, the band gap characteristics of phononic crystal pipeline used to design fluid-structure interaction pipeline system have been widely studied, thus providing a new technical approach to reducing the vibration and noise of the pipeline. In this paper, based on the theory of phononic crystal, the vibration transfer characteristics of the Bragg phononic crystal pipeline under fluid-structure interaction are studied. Combining the transfer matrix method and the finite element method, the band structure and band gap characteristics are calculated. Using the finite element method, the vibration characteristics of the phononic crystal pipeline under fluid-structure interaction effect, the shock excitation of pipe wall and the shock excitation of the fluid are considered. The influence of the fluid-structure interaction on the vibration transmission characteristics of the phononic crystal pipeline is also analyzed. The research results indicate that when the fluid velocity in the fluid-structure interaction pipeline system is small the Bragg phononic crystal pipeline has a good attenuation effect on the shock excitation of pipe wall in the band gap range, and that when the fluid velocity increases the fluid-structure interaction effect becomes significant, the attenuation effect becoming weaker. Bragg phononic crystal pipeline has a certain attenuation effect on the pipe wall vibration caused by the fluid shock excitation near the band gap. The research results are expected to be able to provide a technical reference for the vibration control of pipeline systems under fluid-structure interaction conditions. -
