摘　　要：以封边机除屑系统为研究对象,借助Fluent软件,采用滑移网格技术和离散相模型,对除屑系统内部空气流场和废屑颗粒分布进行三维非定常数值仿真。结果显示,原除屑系统结构进出口压力损失较大,吸附废屑能力较弱;优化后除屑系统结构在刀具转速10000 r/min、出口风压-1700 Pa条件下,进出口压力损失减小64.1%,除屑率增加了30%。现场测试显示,优化后除屑系统的除屑效果大幅度提升,仿真结果与现场测试现象,基本保持一致。A 3D unsteady simulation model was developed for the air flow and waste particle distribution in the chip removal system of the panel-furniture edge banding machine using Fluent software with sliding mesh technologies and the discrete phase model.It was found that the pressure loss at the inlet and outlet of the origin chip removal system was relatively large,and the capability of adsorbing waste chips was weak.According to the analysis,the structure of the chip removal system was optimized.Compared with the original system,the pressure loss at the inlet and outlet was reduced by 64.1%,and the chip removal rate was increased by 30%in the optimized system under the conditions of tool speed at 10,000 r/min and outlet wind pressure of-1,700 Pa.Testing were performed on the chip removal system before and after the optimization.The results showed that the chip removal efficiency was greatly improved after the optimization,and the pilot testing was consistent with the simulation performance.
