摘　　要：以直接称重式电子皮带秤的称重托辊局部区域振动为研究对象.建立数学模型,采用Runge-Kutta法求解计算并揭示称重托辊受力与纵向振动、横向振动之间的关系.计算结果表明:当皮带上的物料分布均匀时,称重托辊受到的竖向力随时间变化,称重传感器输出与皮带和物料的实际重力值有较大的差距,即皮带的振动是电子皮带秤测量误差的主要来源.The local region vibration near the weighing sensor of an electronic belt scale with a direct weighing carrier roller is studied. The mathematical model of the system is presented, Runge-Kutta method is applied to reveal the relationship between the load applied on weighing roller and the vertical vibration and horizontal vibration of the loading belt. The calculation results show that the vertical force on the weighing roller is variable even if the delivery material is uniform on the belt. There are obvious difference between the indicating value of the weighing sensor and the actual gravity of the delivery ma- terial. The measuring error of the electronic belt scale is mainly caused by the belt vibration.
