| 摘要： | Noise absorption predictions for automobile interior trim components and materials have been always important in automotive industry.One purpose of this paper is to introduce how to measure the acoustic materials for having their sound absorption coefficients,using the impedance tube measurement,and then the test results will be compared for finding the differences of the sound absorption coefficients between these materials and discuss which is the key factor of the acoustic materials ' sound absorption coefficients.Additionally,the paper will go further to present the inverse methods through using ' AutoSEA2 ' to prove whether materials ' physical properties right or not and the materials' physical properties were finally confirmed,which is to help people know how to construct a data base of the acoustic materials that can be used for CAE analysis for NVH. |
