摘　　要：实时耦联动力试验将整体结构拆分为数值子结构和物理子结构,采用耦联的数值计算和物理试验来模拟整个系统的动力响应,同时按照实际荷载速率加载试验试件。因此该试验方法综合了拟动力子结构试验和常规振动台试验的优点,既能够进行足尺或大比例尺模型试验,又能够反映速度相关性试件的动力特性。本文首先简要介绍实时耦联动力试验的系统构建和分类,随后详述实时耦联动力试验中的数值积分算法和迟滞补偿方法的研究进展,最后介绍实时耦联试验方法的应用现状。Real-time dynamic hybrid testing（RTDHT） is a method for simulating dynamic structural responses by splitting the system into numerical and physical substructures,where the numerical substructure is simulated and the physical substructure is tested in parallel.Because the testing specimen is loaded in real time rate,RTDHT combines the advantages of pseudo dynamic substructure testing and conventional shaking-table testing.A full-scale or large-scale model test could be implemented and the rate-dependent behaviors of a specimen could be taken into account.This paper reviews the state of the art of RTDHT.Construction and category of RTDHT system are described,and then recent advancements in some technical issues are reviewed,such as numerical integration algorithm and actuator delay compensation.Finally,some applications of RTDHT are demonstrated.
