Vibroacoustics Analysis and Reduction of Liquid-filled Pipeline

摘要

The characteristics of pipeline model construction for vibroacousticanalysis are investigated. The establishment of fluid-structure couplingnumerical models with FE model and FE-SEA hybrid model in pipelinevibroacoustics analysis was proved to be suitable for the wholefrequency domain. Experimental investigations compared with thenumerical results showed the effectiveness of the presented technology.Finally, vibration reduction design of pipeline with application ofdifferent damping materials were evaluated by the proposed technology.
