燃气轮机改装坦克噪声的测试与分析

Analysis and Test of Noise from Gas Turbine Modified Tank

坦克噪声对乘员及战场安全影响很大,根据国军标噪声测量要求,通过对某型燃气轮机改装坦克的噪声进行实车测试与分析,得出了其车内稳态噪声声压级、原地噪声隐蔽性和车内噪声1/3倍频程频谱分布状况,对研究和降低燃气轮机坦克噪声具有参考价值。

The noise from tank affects the crews and safety very much.Based on the requirement of na-tional military standard,analysis and test of the noise status from a type of gas turbine modified tank are conducted,the steady-state noise pressure level inside the tank,the noise hidden capacity on the spot and the noise third-octave band frequency spectrum distribution in the tank are obtained,which has a reference value for the study and reduction of noise from the gas turbine tank.
