EASY5 is a set of multidisciplinary oriented dynamic system simulation software with advantages of rich model library, easy modeling and convenience for secondary development, and etc. The simulation model of earthquake simulation shaking table control system was established based on EASY5, and the system was analyzed with simulation under input of earthquake wave. The simulation results show that EASY5 can simulate the characteristics of shaking table system authentically, and can be used for the refined modeling and the complex algorithm research of earthquake simulation shaking table control system.
