以伺服阀非线性建模为核心,利用MATLAB/SIMULINK建立的电液振动台非线性仿真模型,在与某型号地震模拟振动台实验对比中,仿真出了该系统在某些频段内存在的加速度波形失真趋势,且具有一定的准确性。仿真模型在离心场中电液振动台设计方面的应用表明:量化直观的仿真结果为系统参数设计和优化提供了重要参考;仿真系统为波形失真消除方案设计、控制算法研究和系统参数优化提供了良好的仿真平台。
Taking non-linear model of servo valve as the core, the nonlinear simulation model of electro-hydraulic vibration table established by MATLAB / SIMULINK is used to simulate the vibration of the system in certain frequency range Wave distortion trend, and with a certain accuracy. The application of the simulation model to the design of electrohydraulic shaker in the centrifugal field shows that the quantified and intuitive simulation results provide an important reference for the design and optimization of the system parameters. The simulation system provides a solution to the design of waveform distortion, the research of control algorithm and the optimization of system parameters Good simulation platform.
