| 中文摘要:采用Virtual.Lab Acoustics中的声学有限元法仿真平板结构的隔声性能，结合4.7 mm钢板的空气隔声室试验结果，验证计算方法的收敛性和稳定性。采用该方法对船用复合岩棉板的隔声性能进行数值仿真，提出一种考虑吸声因数的复合岩棉结构的隔声性能仿真修正方法，仿真与试验结果吻合较好。 |

| Abstract: Acoustic finite element method is used to simulate the sound insulation performance of flat panel structure based on Virtual.Lab Acoustics. The convergence and stability of the calculation method is verified by the test results of 4.7 mm steel panel in air insulation room. The sound insulation performance of marine composite rock wool panel is simulated by this method. A correction method of sound insulation performance simulation is proposed considering sound absorption factor. The simulation results agree well with the test results. |
