摘要
通过研究振动台液压系统的工作原理,建立了地震模拟振动台液压系统的仿真模型。建立模型时考虑了作动器刚度、阻尼等多种因素的影响;并对主要参数的敏感度进行了分析。结果表明:该模型的计算结果与振动台的实际响应较为吻合,具有较高的精确度,可为数字化振动台系统的设计提供参考。
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.
