摘　　要：针对电磁振动给料机无法实现自动化调速加料控制的问题,对不同参数下电磁振动给料机加料性能进行了仿真分析和实验研究。首先,利用SolidWorks软件对电磁振动给料机进行了三维建模,并将其导入离散元分析软件EDEM生成了计算模型;然后,在EDEM软件中分别改变电磁振动给料机的振幅、挡板高度、振动频率、振动方向角参数,对其在不同参数下的加料过程进行了模拟仿真;最后,通过实验验证了挡板高度和振幅变化对电振机物料输送流速影响规律与软件模拟研究规律的一致性。研究结果表明:流速随振幅、振动方向角的增加呈二次曲线变化;流速随挡板高度的增加呈线性增长;流速随振动频率的增加呈二次曲线和线性阶段性变化;通过对电磁振动给料机参数的研究,为电磁振动给料机的参数化设计和自动调速加料控制提供参考。Aiming at the problem that the electromagnetic vibration feeder could not realize the automatic speed regulation and feeding control,simulation and experimental analysis research were carried out on the feeding performance of the electromagnetic vibrating feeder under different parameters.First,the three-dimensional modeling of the electromagnetic vibration feeder was established by SolidWorks software,and the discrete element analysis software EDEM was imported to generate its calculation model.Then the amplitude,baffle height,vibration frequency and the vibration direction angle of the electromagnetic vibration feeder were separately calculated in the EDEM software,the feeding process of the electromagnetic vibration feeder under different parameters was simulated.Finally,the experiment verified the consistency of the influence law of the baffle height and amplitude change on the material conveying velocity of the electric vibrator with the software simulation research law.The results show that the flow velocity changes in a quadratic curve with the increase of the amplitude and the vibration direction angle;the flow velocity increases linearly with the increase of the baffle height;the flow velocity changes quadratic curve and linear stepwise with the increase of the vibration frequency.Through the study of the parameters of the electromagnetic vibration feeder,it provides a reference for the parametric design of the electromagnetic vibration feeder and the automatic speed regulation feeding control.
