采用封闭式厂房治理机车滚动试验噪声

Controlling locomotive rolling test rig noise with a closed factory building

液动试验台试验时噪声高达118 d B(A),必须进行封闭处理,而试验时为满足燃烧和通风要求,最大换气量达170万m3/h。因此必须对进气和排气进行有序组织,并对噪声进行封闭处理,换气通风采取针对性措施。

The noise of rolling test rig is as high as 118 d B（ A） during test, which must be controlled with a closed processing, and the maximal ventilation volume must reach 1. 7 million m3/ h to meet with the combustion and ventilation requirements. Therefore, the intake and exhaust must be organized in order, the noise must be insulated and pertinence measures must be taken for ventilation.
