摘　　要：基于等效加速度均方根开展管路结构载荷分析理论和方法研究。提出了由结构振动响应功率谱密度直接获取其单模态区域均方根值的等效白噪声激励的简化计算方法,为管路结构载荷分析的过程中实测数据的快速处理提供了依据。文章最后通过实际算例证明了等效载荷分析及其计算方法的有效性,该方法对管路结构载荷设计与评估具有重要的指导意义。This paper researched the analytical theoretic and method for load of pipeline structures based on equivalent acceleration root mean square.The simplified calculation method of equivalent white noise excitation is presented,which is used for gaining root mean square of single-mode area from power spectral density of structure vibration response mean while the method provides reference for rapid data processing in the load analysis of pipeline structures.Eventually,through the examples demonstrate the algorithm’s effectiveness and reliability,which has guidance meaning for loads design and evaluation technology for pipeline structures.
