Abstract (English): The design of the cyclone separator in the pneumatic conveying system of the plot corn harvester was mainly simulated and analyzed, and the internal flow field of the cyclone separator was simulated by using EDEM-Fluent software. The simulated motion of the particles was simulated by EDEM software to observe the trajectory of the particles in the simulation, and then the airflow flow field in the cyclone separator was simulated and analyzed by Fluent software, and the two were coupled to observe the motion of the corn kernels under the action of the airflow, and to analyze the force of the corn kernels in the process of motion and the collision characteristics of the corn kernels, and to combine the structure of the cyclone separator with the analysis of the parameters and the analysis of the collision characteristics of the corn kernels. Combined with the analysis of the structural parameters of the cyclone and the motion analysis of the corn kernels, the optimal structural parameters of the cyclone separator were obtained by using the airflow rate, the height of the lower cone and the cross-sectional area of the feed opening as test factors, the breakage rate of the corn kernels as the test criterion for the test design, and the optimization of the method for the multi-objective variables and the establishment of the optimization model, which resulted in the optimal structural parameters of the cyclone separator: air flow rate of 30 m/s, the height of the lower cone of 400 mm, and the cross-sectional area of the feed opening of 0. 08 m2. The breakage rate of corn kernels can reach 0. 782%, superior to traditional similar device. Ten sets of bench tests were carried out, and the verification results were in line with the simulation results, indicating that the improved cyclone separator device can meet the harvesting requirements of corn harvesters.

Abstract (Chinese): 主要对小区玉米收获机气力输送系统中的旋风分离器的设计进行仿真分析,运用EDEM-Fluent 软件对旋风分离 器内部流场进行了仿真模拟。通过EDEM 软件模拟颗粒的仿真运动,观察模拟中颗粒的运动轨迹,再通过Fluent 软件对 旋风分离器中的气流流场进行模拟分析,将两者进行耦合,以观察玉米籽粒在气流作用下的运动情况,并对玉米籽粒在运 动过程中的受力情况和玉米籽粒碰撞特性进行分析。结合旋风分离器的结构参数和对玉米籽粒的运动分析,以气流流 速、下锥体高度和入料口横截面积作为试验因素,以玉米籽粒破损率为指标进行试验,对多目标变量进行方法优化并建立 优化模型,得出旋风分离器最佳结构参数:气流流速为30 m/s、下锥体高度为400 mm、入料口横截面积为0. 08 m2,玉米籽 粒破损率为0. 782%,优于传统同类装置。进行了10 组台架试验,验证结果与仿真结果相符,表明改进的旋风分离器能够 满足玉米收获机的收获要求.
