摘　　要：为实现新型微量润滑装置的自适应控制,需研究拉瓦尔式雾化器雾化参数对其雾化结果的影响规律。采用VOF to DP M模型,对其中润滑油的破碎过程进行数值模拟研究,统计研究刀具平面接收的油滴粒径及其数量,与实际车削试验进行对比研究。结果表明:拉瓦尔式雾化器拥有良好的雾化效果,并且随进气量的增大,油雾粒径减小,喷嘴喷雾扩散程度增大,而润滑油量对油雾粒径影响较小。To achieve adaptive control of the new micro lubrication device,it is necessary to study the influence law of the atomization parameters of the Laval-type atomizer on its atomization results.The VOF to DPM model is used for numerical simulation research on the lubricant crushing process,and the particle size and quantity of lubricant droplets received by the tool plane are statistically studied and compared with the actual turning test.The results show that,the Laval-type atomizer has good atomization effect,and with the increase of air intake,the lubricant mist particle size decreases,and the degree of spray diffusion from the nozzle increases,while the lubricant amount has little influence on the lubricant mist particle size.
