中文摘要：

通过有限元方法建立大型带式输送机的动态模型,并通过基于系数矩阵的有序实Schur分解的模型降阶法对带式输送机系统模型进行降阶处理,得到低阶模型,绘出其频率特性Bode图,比较降阶前后系统的频率特性。

英文摘要：

Dynamic model of large belt conveyor is established via finite element method,and belt conveyor system model order is reduced via model reduction method of real Schur decomposition based on coefficient matrix.Based on it,the paper acquires low order model,draws its frequency characteristic Bode diagram and compares the frequency characteristics of the system before and after the reduction.
