摘　　要：针对废旧塑料薄膜的特性,对气流场中塑料颗粒进行受力分析,得到了塑料混合物的运动规律,建立了其在气流场中水平和竖直位移运动方程;运用MATLAB工具研究了风速气流倾角参数对运动轨迹的影响,确定了塑料混合物分选的最佳风速为10m/s,最佳气流倾角为10°,为塑料复合分选中的振动分选奠定了基础.The plastic particles in the flow field are analyzed according to the characteristic of plastic mixture, the plastic mixture law of motion is obtained, and the horizontal displacement function of the plastic mixture in airflow field is established. The effect of some parameters such as wind speed and sloping angle of airflow are studied with MATLAB, the best wind speed and the best sloping angle of airflow for separation of waste plastic membrane mixture are 10m/s and 10° respectively. The study lays the foundation for plastic mixture separation.
