| 摘 要： | 涡轮风扇发动机试车台空气流量大,试车噪声呈宽带强噪声,其中突出的低频域噪声可远距离传播,易造成大范围的环境污染。为掌握某型涡轮风扇发动机在室内试车时的噪声特性,并检验试车台建筑物和各项降噪设备的效果,我们对新建试车台的声环境进行了测量。通过对该试车台内、外环境噪声数据的分析,表明新建试车台的声环境满足了我国有关规范的要求。本次研究工作对今后试车台的声学设计具有重要的借鉴意义。

| Abstract: | As a result of turbofan engine’s a great lot air flux and broad-band noise,especially low frequency noise,the environment will be polluted seriously by noise when the aero engines are tested.In order to realize the characteristic of turbofan engine and inspect the effect of noise control in the new test cell,its sound environment is tested.Through noise data collection and power spectrum analysis of turbofan,the results indicate that sound environment of the new test cell is satisfied all demands of some concerned native criterion.This work plays an important part in the designing test cell for the future. |
