摘　　要：花瓣因质量小、重量轻,在色选机中运动会受到空气阻力干扰。为研究花瓣色选机中真实的花瓣抛料轨迹,通过空气动力学对带有空气阻力的离心式抛料进行分析,获得花瓣抛料的轨迹方程;再通过EDEM软件的API接口,加入空气阻力模型对花瓣抛料进行数值模拟,将色选机内部花瓣抛料运动过程可视化。实验结果表明:数值仿真结果和理论分析得到的抛料轨迹具有一致性;加入空气阻力的数值仿真结果对花瓣色选机设计改进有很大帮助。The petal is disturbed by air resistance due to its small mass and light weight in the color sorter.In order to study the true petal throwing trajectory in the petal color sorting machine,the centrifugal throwing with air resistance is analyzed by aerodynamics to obtain the trajectory equation of the petal throwing.Then through the API interface of EDEM software,the air resistance model is added to simulate the petal throwing,and the process of the petal throwing motion inside the color sorter is visualized.The results show that the numerical simulation results and theoretical analysis are consistent with the throwing trajectory.The numerical simulation results of adding air resistance can greatly improve the design of the petal color sorter.
