柴油发电机组的噪声控制

NOISE CONTROL OF DIESEL GENERATOR SETS

随着船舶朝着高速、大功率方向发展 ,柴油发电机组的振动和噪声污染问题日趋严重。以某中等功率船用柴油发电机组为例 ,采取振动隔离、安装消声器、粘贴约束阻尼和吸声材料等综合技术手段对其进行噪声控制 ,取得了很好的噪声控制效果。该控制措施合理 ,成本较低 。

Along with the development of boats and ships towards the direction of high speed and large capacity, Pollution problems of vibration and noise from diesel generator sets are becoming increasingly serious with each passing day. Taking diesel generator set on a ship of medium capacity as example, comprehensive measures, such as isolating vibration, erecting noise reducer, and pasting bind damper and noiseabsorbing materials etc., have been taken for controlling noise, obtaining excellent effectiveness of noise control. The said measures are reasonable, having low cost, providing reference value for controlling noise of other power units.
