摘要
离心机二维地震模拟振动台是目前世界用于地震研究的最先进的实验设备之一,系统仿真为该设备的研制提供了新的工具。介绍了一种离心机"水平+垂直"二维地震模拟振动台的系统组成,分析了该系统的基本特性,并借助MATLAB/SIMULINK软件建立了系统的非线性仿真模型。模型在算例下的仿真运行和结果表明:仿真程序运行正常,仿真结果正确,该模型可以为系统设计提供辅助平台。
The 2D earthquake simulation shaker is a kind of the most advanced equipment used for earthquake research at present in the world. The system simulation provides a new tool for the shaker design. One kind of horizontal and vertical 2D earthquake simulation shaker was introduced, and its characteristics were analyzed. Then its nonlinear simulation model was established by MATLAB/SIMULINK software. The result of model simulated in a simulation example indicates that the model program runs well and the result is right; the simulation model is helpful for the shaker design.
