摘要
介绍了隔振作为柴油机降噪方法的基本原理,描述了该方法实施的基本步骤。隔振降噪法在C型柴油机应用中取得了明显的降噪效果,整体声功率级降低了1～2dBA。
Vibration isolating theory is adopted as a measure of reducing diesel engine＇s noise radiation. Basic procedures and steps of applying this measure are described. The measure is taken to a C type diesel engine with a good result. The SPW of the engine is reduced by 1-2 dBA.
