| Abstract: | 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. |
