摘要

以充液管路振动控制为目标研究周期附加质量的新型声子晶体管路振动传播特性。利用传递矩阵法建立周期附加质量充液管路带隙理论模型，深入分析影响带隙特性关键因素，包括附加质量尺寸、安装位置及材料阻尼。数值计算表明，声子晶体管路存在低频振动带隙可有效抑制振动传播，且设计方法简单、操作方便、减振效果明显，以期为充液管路减振设计提供新思路。

Abstract

In this paper, the vibration transmission properties of a Phononic Crystals (PC) pipe with mass added periodically are investigated, aiming at controlling the vibration of the fluid-filled pipe system. Based on the transfer matrix method, the band gap of such a fluid-filled PC pipe is calculated. The numerical calculation shows that the PC pipe characters a low-frequency vibration band gap, which can be used to suppress the vibration propagation in the pipe system. Further, the influence of several key parameters, such as the size, installation position of the added mass and the damping factor of the material, on the band gap mudulation of PCs pipe are discussed detailedly. Results reveal that the band gap of the PC pipe is adjustable and vibration reduction effect is apparent, thus it can conclude that the periodic design method proposed in this paper could provide a new approach for the vibration control of the fluid-filled pipe system.
