- 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.
