Design and Matlab Simulation of Electro-Hydraulic Servo Oscillation System for Continuous Casting Mold

从连铸结晶器振动技术的发展需求出发,为实现在高振频、小振幅的要求下系统能保持较高的精确度和稳定性,系统设计采用了电液伺服控制的非正弦振动技术。首先对结晶器机械振动装置进行了动力学分析,根据得到的数据结合设计要求进行液压系统计算,并建立了数学模型。利用Matlab/Simulink软件对系统仿真,检验结果表明该系统符合设计要求,并可显著提高铸坯表面质量。

To ensure high precision and stability of oscillation system as well as high frequency and small amplitude, the system was designed by using the non-sinusoidal oscillation technology of electro-hydraulic servo control. First, the oscillation system of continuous casting mold was dynamically analyzed. Then, based on the data obtained from the electro-hydraulic system together with the design requirements,a mathematical model was established. Finally, the system was simulated using the Matlab/Simulink software. The simulation results showed that the system can meet the requirement of design and can significanlty improve the surface quality of billet.
