摘　　要：砂磨机是较为典型的打磨类电动工具产品,作业时产生大量粉尘。在吸尘风叶的作用下,粉尘通过砂纸和砂盘上的孔洞经出尘管到达集尘袋。该类产品对于吸尘风道的设计至关重要。运用计算流体动力学(Computational Fluid Dynamics,CFD)优化砂磨机吸尘风道,获得最佳设计方案,可以提升砂磨机作业效率。通过对风道优化前后的仿真分析以及样机实际打磨测试数据的对比,验证CFD技术对手持式砂磨工具进行风道优化设计的可行性。The sander is a typical polishing electric tool product,which generates a lot of dust during operation.Under the action of the suction fan blade,the dust passes through the holes on the sandpaper and sand disc and reaches the dust bag through the outlet pipe.The design of the dust suction duct is crucial for this type of product.By optimizing the suction air duct of the sander using Computational Fluid Dynamics(CFD),the best design scheme might be obtained to enhance the grinding efficiency.Through a comparison of simulation analyses conducted before and after optimizing the air duct,along with actual grinding test data from prototype machines,the feasibility of using CFD technology for optimizing the air duct design in hand-held sanding tools is verified.
