摘　　要：本文根据平面波正入射基本理论,以三明治夹芯平板结构为对象,利用多物理场有限元软件Comsol开展了声学特性仿真分析,研究其在正入射条件下的声学特性。首先通过与单一平板结构理论解的对比,验证了该仿真模型的准确性;随后讨论了正入射时,平板厚度与平板材料参数等变化对于三明治夹芯平板反射性能与透射性能的影响规律。In this paper,according to the theory of plane wave normal incidence,and based on the finite element soft-ware COMSOL,a simulation model for the acoustic characteristics of sandwich plate is established.The acoustic character-istics of sandwich plate under normal incidence are studied,and the accuracy of the simulation model is verified by compar-ing with the theoretical solution of a single plate structure.The effects of plate thickness and material parameters on the re-flection and transmission properties of sandwich plates are discussed.
