    摘要:

    为了减少管状带式输送机启机后产生的振动所带来的不利影响,现设计一种颗粒阻尼型声子晶体板。通过有限元法对声子晶体带隙成因进行研究,并对颗粒阻尼型声子晶体板进行建模。利用COMSOL得到颗粒阻尼型声子晶体的能带与传递损失图形,并对非颗粒阻尼型声子晶体与颗粒阻尼型声子晶体进行传递损失分析。之后通过实验得到颗粒型声子晶体减振效果达到70.43%相比非颗粒型声子晶体增加37.42%,为颗粒阻尼型声子晶体在管带机上的减振应用提供理论支撑。

    Abstract:

    In order to reduce the adverse effects of vibration when the tubular belt conveyor is started, a phonon crystal plate of particle damping is designed. The formation of the band structure of the phonon crystal is analyzed by the finite element method, and the phonon crystal plate of particle damping is modeled. The band structure and transmission loss patterns of the phonon crystal plate of particle damping are obtained and analyzed by COMSOL,and analyses the transmission loss of non-particle damping phonon crystal and particle damped phonon crystal. Through experiments, the vibration reduction effect of phonon crystals of particle damping reaches 70.43% comparing to 37.42% for non-particle damping phonon crystal, providing theoretical support for the application of phonon crystals plate of particle damping for vibration damping on tubular belt conveyor.
