摘　　要：针对大白菜种子清选中的难题,研制了一种风筛式大白菜种子清选装置。使用EDEM软件对振动频率、振幅和振动方向角进行了数值模拟试验,并分析了不同工作参数下筛面物料运动速度、筛下物料分布和振动筛分效果。研究结果表明:当振动频率为14 Hz、振幅为5 mm、振动方向角为35°时,振动筛的筛分效果最佳。室内验证试验结果表明:模拟结果与实测结果基本一致,证明了EDEM软件在振动筛数值模拟方面的可行性。研究结果可为大白菜种子清选装置的筛分效果分析和工作参数设定提供理论依据。In order to solve the problem of Chinese cabbage seed cleaning,a kind of fan-sieve type Chinese cabbage seed cleaning device was developed.This paper used EDEM software to simulate the vibration frequency,amplitude and vibration direction angle,and analyzed the material movement speed on the screen surface,the material distribution under the screen and the screening effect under different working parameters.The results showed that the screening effect of the vibrating screen was the best when the vibration frequency was 14 Hz,the amplitude was 5 mm and the vibration direction angle was 35°.Through the indoor verification test,the results showed that the simulation results were basically consistent with the measured results,which proved the feasibility of EDEM software in the numerical simulation of vibrating screen.This study provided a theoretical basis for the screening effect analysis and working parameter setting of Chinese cabbage seed cleaning device.
