建立了带式输送机系统的简化模型，考虑驱动滚筒刚体运动与胶带弹性运动的耦合，导出了该系统纵向振动的动力学方程，确定了合理的边界条件。以神府矿区某矿主平峒胶带机为例，对起、制动过程中平衡锤的振动特性作了数值计算，并进行了结果分析，计算结果与实测数据基本相符。 A simplified model of the belt conveyor system is established. Considering the coupling of the rigid body movement and the elastic belt movement, the dynamic equations of the longitudinal vibration of the system are derived and the reasonable boundary conditions are determined. Taking a mine main flat belt conveyor in Shenfu Mining Area as an example, the vibration characteristics of the counterweight during the braking process are numerically calculated and the results are analyzed. The calculated results are in good agreement with the measured data.
