Student thesis: Doctoral Thesis


In recent years the concept of seismic isolation and vibration mitigation has deepened Through the application of structural control systems damage to structures caused by earthquakes can be reduced In order to verify the effectiveness of the structure control system shaking table test in which the structure is replaced by a scaled-down model is the most direct verification method However due to the cost and space limitation the real-time hybrid testing technology is developed which can present the response of full-scale controlled structure through the shaking table in real-time However there are still uncertainties in the process of the experiment Therefore this thesis takes the active mass damper (AMD) as an example to discuss the influence of time delay on the active control system in the beginning Then carry out the preliminary planning of real-time hybrid testing by hardware-in-the-loop (HIL) simulation which can simulate a complex system in real-time Afterward conduct performance test to verify the working range of the AMD device then use the system identification method including FRF and OKID/ERA to obtain the frequency domain performance and transfer function of the AMD In this way the results of the proposed framework of HIL simulation can be adopted and compared with the previous real-time hybrid testing results to verify the accuracy of the identified transfer function Therefore through the identification and testing in this study the process and framework of this hardware simulation can be used to evaluate the feasibility and the results of real-time hybrid testing or shaking table test in the future Furthermore the probability of success in an experiment can be greatly improved
