| 5 | 强化滚压工艺优化薄壁管内表面质量显示文摘供水、排水管道内表面的生物膜滋生在飞机设计中是让人相当头痛的一个问题。微生物的滋生会导致供水管道横截面积的减小。在飞机的排水系统中,尤其是污染程度较重的排水管道中,滋生的微生物附聚在管道内表面会带来诸多不良后果。由于滋生的微生物堵塞了管道,因此经常需要对管道进行清理、疏通,甚至更换管道和管道附件,从而带来火量的停飞检修时间和高昂的检修费用。在联邦政府“Nemako新型防腐蚀航空材料”项目的框架内,多特蒙德技术大学的科研人员对材料表面抵抗微生物附聚的性能进行了检测试验。 | Dirk Biermann Hendrik Abrahams Moritz Fuss | 2015 | 现代制造2015，0，32： | 0 |

| 8 | Experimental and computational analysis of the coolant distribution considering the viscosity of the cutting fluid during machining with helical deep hole drills显示文摘An experimental analysis regarding the distribution of the cutting fluid is very difficult due to the inaccessibility of the contact zone within the bore hole.Therefore,suitable simulation models are necessary to evaluate new tool designs and optimize drilling processes.In this paper the coolant distribution during helical deep hole drilling is analyzed with high-speed microscopy.Micro particles are added to the cutting fluid circuit bya developed high-pressure mixing vessel.After the evaluation of suitable particle size,particle concentration and coolant pressure,a computational fluid dynamics(CFD)simulation is validated with the experimental results.The comparison shows a very good model quality with a marginal difference for the flow velocity of 1.57%between simulation and experiment.The simulation considers the kinematic viscosity of the fluid.The results show that the fluid velocity in the chip flutes is low compared to the fluid velocity at the exit of the coolant channels of the tool and drops even further between theguidechamfers.Theflow velocity and the flow pressure directly at the cutting edge decrease to such an extent that the fluid cannot generate a sufficient cooling or lubrication.With the CFD simulation a deeper understanding of the behavior and interactions of the cutting fluid is achieved.Based on these results further research activities to improve the coolant supply can be carried out with great potential to evaluate new tool geometries and optimize the machining process. | Ekrem Oezkaya Sebastian Michel Dirk Biermann | 2022 | Advances in Manufacturing2022，10，2： | 0 |
