摘要
发动机噪声源的识别是控制发动机噪声的一项关键技术,传统的办法是用仪器分别测试噪声源,测试办法复杂,仪器多。文中首次提出了,根据发动机的混叠噪声,用盲分离算法可识别出发动机的外部噪声源。用两个试验验证了新办法识别噪声源的有效性,且测试的仪器少。
Identification of engine noise source is a critical technique of controlling engine noise. Traditionally, each of noise sources is separated to test. These tests are complicate by many instruments. engine surface noise sources are strated this method efficient to i separated according to aliasing noise of engine. Experiments have demondentify engine noise source, and only a few instruments are necessary.
