天然气输气管道噪声源形成机理研究
Research on the formation mechanism of noise sources in natural gas pipelines
摘要
Abstract
This study on noise radiation from natural gas pipelines presents a framework that integrates pipeline vi-bration and noise testing technology with fluid simulation to identify sound sources in gas pipelines.The framework combines both experimental and simulation approaches.By analyzing the internal flow characteristics of the pipe-lines and using actual vibration and noise test data as inputs,the spatial and frequency characteristics of the prima-ry vibration and sound sources in natural gas pipelines were identified.The generation and propagation mechanisms of noise in these pipelines were clarified,confirming the effectiveness of the proposed noise source identification framework.Ultimately,the study revealed the mechanisms behind noise formation in natural gas pipelines,provi-ding technical support for noise control in these systems.关键词
