摘要:
最小二乘复指数识别法( least squares complex method,LSCE) ,不仅适用于弱阻尼也适应于强阻尼密集模态识别.针对某轿车双排气管,采用LSCE法进行排气管试验模态分析,得到该排气管的模态分布比较密集的结论.试验表明,LSCE法对模态参数识别具有很强的适应性.
Abstract:
Identification method of least squares complex exponential LSCE ( least squares complex method) is applied to both the weak and strong damping damping to identify the intensive modal. For a car dual exhaust pipes, exhaust pipe experimental modal has been to be analyzed by using LSCE method and the conclusion is drawn that modal distribution of the exhaust pipe is more intensive. The tests showed LSCE method has strong adaptability for modal parameter identification.
