Due to its high strength-to-weight ratio, composite materials have been widely applied in aerospace manufacturing. However, some challenges are facing in fabrication and assembly of the parts with composite materials. One of them is how to collect the dwarf and dust generated from the drilling operation, especially in an open environment when the composite parts are assembled, since a large number of holes need generating to rivet the parts together when the parts with composite materials are assembled in an aircraft structure. The efficiency of dust extraction is crucial to the healthy operating environment and the quality of the assembled component. In this paper, three conceptual designs of automatic dust extraction are proposed and compared, and the best design with the hood fastened on the drilling spindle has been selected and analyzed. Its design parameters have been identified; a systematic procedure has been proposed for the design optimization; the process of the dust extraction has been modeled and simulated using the COSMOSFloWorks. Taguchi method is applied to optimize the design. The process of the dust extraction has been validated through animation. 相似文献

The importance of the porous structure of coke in industrial usage has been recognized for many years but the difficulties involved in determining by manual microscopic methods, quantitative details of the structure precluded comprehensive and detailed studies. With the advent of computerized image analysis systems it has become possible to overcome many of the practical difficulties associated with the determination of structural data for a material as heterogeneous as metallurgical coke. Techniques based on reflected light microscopy and automatic image analysis have been developed to the extent that representative and reliable structural characterization of coke can be achieved. The data so obtained have been used to derive strength/structure relationships which enable coke strength to be predicted with a standard error comparable with that of the experimental determination and the structural characterization now offers an additional means of defining coke quality with potentially significant industrial applications. 相似文献
