【摘要】 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。更多还原

【Abstract】 A simplified modal of belt conveyor is established. The dynamic equation and rational boundaries of the system are derived, in which the movement is coupled by the rigid - body motion of drive pulley and the elastic motion of belt. The vibration characteristics of tension weight on the conveyor in Shenfu mine district during swing or stopping period are calculated and analyzed. The results are consistent generally with test data.更多还原
