| 摘 要： | 对LG5030GJY型流动加油车加速行驶车外加速噪声进行被动降噪改进设计。该流动加油车原车状态的加速行驶车外噪声为77.5dB(A),主要噪声源为发动机和排气噪声,车外加速噪声随着发动机转速的上升而加大,加速噪声最大声级频谱峰值主要集中在100～200Hz的低频段。采取在驾驶室下部及发动机周围加装ABS+2.5mm隔音毡进行降噪,在发动机和水散热器支架上安装减振垫,对发动机进行隔声减振处理。实施降噪改进措施后,该流动加油车的加速行驶车外噪声能够满足77 dB(A)标准值的要求。

| Abstract: | The exterior acceleration noise of LG5030GJY type mobile fuel tanker during accelerating was reduced by passive noise reduction design.The original exterior acceleration noises was 77.5dB（A）,which mainly from the engine and exhaust noise. The exterior acceleration noise was increase when the speed of engine was increase.The maximum noise spectrum peak is mainly on the 100～200Hz.By equipping the bottom of cab and the engine with ABS＋2.5 mm and installation of damping pad on engine and water radiator bracket,the exterior acceleration noise can be reduced to the standard values（77dB（A））. |
