摘　　要：在对磨削区气流运动特性研究的基础上,应用FLUENT仿真软件建立磨削区有限元模型,仿真计算不同工作条件下磨削区气流的压力及速度分布特性.结合磨削加工实验,研究磨削区气流运动对工件表面完整性的影响并对仿真结果进行验证.研究结果表明,磨削区气流运动会阻碍磨削液有效进入磨削区.当磨削液喷入方位接近砂轮与气流运动的速度同向区时,可提高工件表面质量,磨削液的利用效果好,磨削过程绿色度得到提高.Based on the research of airflow movement characteristics in the grinding zone, FLUENT was used to build the finite element model to simulate and calculate pressure distribution and velocity distribution on different working conditions. Combined with the grinding experiment, influence factors of airflow movement on the integrity of the work piece surface were studied and the simulation results were verified. The results indicated that airflow movement in the grinding zone impedes the grinding fluid into the grinding zone. When the injection position of grinding fluid was close to the area with the same direction of wheel rotation linear velocity and airflow velocity, the surface quality of the work piece improved, the utilization rate of grinding fluid and the green degree of grinding raised.
