【Abstract】 Through studying the working principle of hydraulic vibration table test system,the simulation model of the earthquake simulation hydraulic vibration table was established. The actuator stiffness,damping and other factors were considered when modeling and the sensitivity of the main parameters was analyzed. The results show that the results of the model calculation is quite tallied with the actual response of the vibration table with high accuracy,which can provide reference for the design of digital vibration table system.更多还原
