Comparisons of nozzle orifice processing methods using synchrotron X-ray micro-tomography

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2012年第3期13卷 182-188页

作者： Zhi-jun WU Zhi-long LI wei-di huang Hui-feng GONG Ya GAO Jun DENG Zong-jie HU School of Automotive Studies Tongji University Shanghai 201019 China

Based on the high flux synchrotron X-ray of the Shanghai Synchrotron Radiation Facility (SSRF), high precision 3D digital models of diesel nozzle tips have been established by X-ray micro-tomography technology, which reveal the internal surfaces and structures of orifices. To analyze the machining precision and characteristics of orifice processing methods, an ap- proach is presented based on the parameters of the internal structures of nozzle orifices, including the nozzle diameter, the orifice inner surface waviness, the eccentricity distance and the angle between orifices. Using this approach, two kinds of nozzle orifice processing methods, computerized numerical control drilling and electric discharge machining, have been studied and compared. The results show that this approach enables a simple, direct, and comprehensive contrastive analysis of nozzle orifice processing methods. When processing a single orifice, the electric discharge machining method has obvious advantages. However, when there are multiple orifices, the error levels of the two methods are similar in relation to the symmetry of distribution of the orifices.
