Abstract:
In order to overcome the size and mass restrictions of the experimental structure and reduce experimental costs in shaking table test, substructure experimental technique was used in real time dynamic hybrid testing for shaking tables(RTDHTST), and the new type of RTDHTST method was put forward. Furthermore, the basic principle of RTDHTST was introduced, and two real-time loading modes and specific loading process were analyzed. Meanwhile, the characteristics, stability and feasibility of numerical integration algorithm with an example were discussed. Numerical simulation results show that, when the numerical integration step size is small enough, and the experimental control system does not lag behind, the results of the RTDHTST agree well with the results of the whole structure test.
