摘要：

This study develops a numerical simulation model of a three-dimensional (3D) six-degree-of-freedom (6-DOF) seismic simulation shaking table system through Matlab/Simulink. The amplitude-frequency responses and motion displacement curves could be obtained from the simulations. Thus, the motion characteristics could be analysed based on the simulated results obtained. The results show that this model can successfully simulate the nonlinear dynamic characteristics, such as the frequency of oil column, which shows consistency with the real seismic shaking table experiments. The off-line parameters, such as three-variable control, amplitude/phase control, adaptive harmonic cancellation, adaptive inverse control and online iteration, could also be adjusted in the simulations so as to achieve the accuracy demand of the control system.
