Electrohydraulic shaking tables provide a direct means to evaluate structural performance under actual vibration conditions. The control–structure interaction is one of the most important reasons for the degradation of the control performance of the shaking table. This article establishes a series of novel analytical models to investigate the control–structure interaction effects between double shaking tables and test structure. These models are the model of shaking table, the model of control error signal, the flow requirement model of servo valve, the force requirement model of actuator, and the resonance response model of structure. Based on the analytical models of the flow requirement model of servo valve, force requirement model of actuator, and resonance response model of structure, a comprehensive simulation study is conducted under different structural conditions. The study reveals the influence trend and the influence degree of the control–structure interaction on the models. Furthermore, the applications in experiments, the suggestions for the designing of the shaking table, and the deeper explorations of the control–structure interaction are obtained.

电液振动台为评估实际振动条件下的结构性能提供了直接的手段。控制结构相互作用是振动台控制性能下降的最重要原因之一。本文建立了一系列新颖的分析模型，以研究双振动台和测试结构之间的控制结构相互作用。这些模型是振动台模型，控制误差信号模型，伺服阀的流量需求模型，执行器的力需求模型以及结构的共振响应模型。基于伺服阀流量需求模型，执行器力需求模型和结构共振响应模型的分析模型，在不同的结构条件下进行了全面的模拟研究。研究揭示了控制结构相互作用对模型的影响趋势和影响程度。此外，还获得了在实验中的应用，振动台设计的建议以及对控制结构相互作用的更深入的探索。
