Transmission Coefficient of Wave in the Engineering Ceramic Materials
摘要
Abstract
For the problem of the acoustic transmission coefficient of wave in engineering ceramic materials, the mathematical model of the acoustic transmission coefficient is built according to the wave equation, transfer matrices and gas-solid boundary conditions . The rule of acoustic transmission coefficient is researched under the condition that the different frequency wave vertically incidence in the ceramic material .Simulation results show the acoustic transmission coefficient is the maximum when thickness of ceramic material is an integer time of half wavelength or the frequency-thickness is integer time of half of product of acoustic velocity of ceramics and its thickness .It provides the theoretical base for sound insulation performance analysis and acoustic detection of the ceramic .关键词
