Abstract
- Aiming at the vibration reduction problems of pipeline systems under high temperature, a high temperature mechanics model of the metal rubber coated damping structure of the pipe-lines was established by equivalent linearization method. The model was used for analyzing the stiffness and response amplitude of metal rubber treated with different temperatures. The thermal-vibration joint test system of the pipelines was set up firstly. Then the damping performance of the coated damping structure of the pipelines was verified with different ambient temperatures and metal rubber densities, where the insertion loss was taken as the evaluation index. The results show that reducing he density of metal rubber may effectively increase the vibration attenuation effectiveness of the pipelines. At the same time, the effect of the ambient temperature on the metal rubber coated damping structure is negligible, indicating that the coated damping structure may work well in a high temperature environment.
