摘　　要：统计能量分析(statistical energy analysis,SEA)是一种处理复杂耦合系统高频动力学响应的常用计算方法。该综述从经典统计能量分析(classical statistical energy analysis,CSEA)入手,详细介绍CSEA演化为SEA的进展历程,并从理论发展和实际工程应用过程两方面对前人所做的大量工作进行概述,对SEA提出至今的理论推导及应用最新进展进行了系统归纳分析和总结。详细介绍总结了统计能量分析在工程实际中的一些典型成功应用案例及未来研究趋势。Statistical energy analysis(SEA)is a common method to deal with high frequency dynamic response of complex coupled systems.Here,starting from the classical statistical energy analysis(CSEA),the evolution process from CSEA to SEA was introduced in detail.A lot of studies done by past researchers were summarized from the two aspects of theoretical development and practical engineering application process.The latest development of theoretical derivation and application of SEA were analyzed and summarized.Some typical successful application cases and future studying trends of SEA in engineering practice were introduced and summarized in detail.
