摘　　要：实时耦联动力试验(RTDHT)是一种将物理模型试验和数值求解计算实时耦联在一起进行整体结构动力反应分析的新型结构动力试验方法。构建实时耦联动力试验系统将面临数值子结构实时计算、数据实时传输、加载器精确加载等问题。本文首先以清华大学新近建成的一套基于振动台的实时耦联动力试验系统为例,对试验系统构建中面临的问题以及相应的解决方案进行了阐述,对构建实时耦联动力试验系统提出了一些指导性的建议。随后简要介绍了利用该系统已经进行的一些实时耦联动力试验,并对实时耦联动力试验可能的应用前景进行了探讨。Real-time dynamic hybrid testing（RTDHT）is a novel testing method coupling physical substructure testing with numerical substructure calculation.Several key problems have to be solved to construct a RTDHT system, such as real-time calculation of numerical substructure,loading accuracy of physical substructure,and real-time data-transfer between substructures.In this paper,these problems are illustrated in detail and their solutions are introduced on the basis of a newly-built RTDHT system at Tsinghua University.Some suggestions are made to guide the RTDHT system construction.Finally,some tests already done by using this system and some possible applications in the future are summarized.
