摘要
声子晶体是一种重要的声人工材料,由于其独特的声波传播特性而得到广泛研究,对声人工材料中声波传播特性的研究具有重要意义。文章综述了声子晶体带隙特性、带隙机理以及吸声特性的研究进展,并对其在船舶减振降噪中的应用前景进行了展望。
Phononic crystal is an important acoustic artificial materials. It has been extensively investigated because of their characteristics of wave propagation, which is of great significant. This paper summarizes the research progress of band gap properties and mechanism, and acoustic absorption. This paper provides a reference for the fabrication and wave propa- gation investigation of acoustic artificial materials. Meanwhile, phononic crystal shows outstanding features in reducing vibration and blocking noise, and the band gap characteristics in suppressing vibration source of strength, vibration isolation and damping mechanism have been preliminary study, which laid a good foundation for the application of phononic crystal on vibration of the ship noise reduction.
