| 摘 要： | 简要介绍了盲分离基本思想及AC算法,提出盲分离仅用测得的柴油机混叠噪声源可分离干扰噪声、机械噪声和燃烧噪声。试验验证了在存在干扰噪声时,新办法也可识别出有用的噪声源,且测试所用的仪器少,从而为发动机噪声源识别提供了一种行之有效的新办法。

| Abstract: | The basic theory and AC algorithm of blind sources separation are briefly introduced,and then we proposes a novel approach to identify engine noise sources.The approach utilizes blind sources separation to identify engine mechanical noise and combustible noise according to their mixing noise under the condition of noise perturbation.Experiments demonstrate this method efficient to identify engine noise source,and less instruments are needed,consequently providing an effective technology for Engine noise source identification. |
