| Abstract: | According to damping testing standard,this paper examined the influence factor in experimental damping measurement,analyzed the structural damping equivalent error.Made up of test specimen by using glass fiber and examined the damping value of undamaged and damaged cantilever beam.The results showed that the location of damage was crucial to modal parameters.Anad measured structural damping with different amplitude,the results were stable met the engineering requirements in linear area. |
