,http:/amid.hanyang.ac.kr,The Korean Society of Mechanical Engineering,The study of wiper shape for the uniformed pressure on the glass,Advanced Materials & Innovative Design Lab.,Three-dimensionally Reconstructed Model of the Cerebral Aneurysms and Fluid Analysis,We focused on uniformed pressure which is very important thing for well polished condition. This study was approached by changing shape. So, primary curvature was changed and three type of results was got by changing yoke angle, yoke thickness and rail spring thickness. The conclusion is that in flat type wiper included yokes case, Yoke angle is sensitive shape parameter and Yoke thickness can reduce Yoke angles sensitivity. This study was limited in case of flat type wiper included yokes; however this study will be approached another type wiper.,Even though we changed small angle of about 1 that can be easily occurred in manufacturing line, the curve of wiper contact pressure changed a lot. The contact pressure also can be changed by different yoke thickness. Rail spring thickness variable is not important for uniformed pressure.,KSPE,The cerebral aneurysms is a very serious disease and gains more and more attention of researchers. When the cerebral aneurysms rupture, it will lead to humans death. CFD software supply researchers a great help. While simulating, the reconstruction of high accuracy 3-D aneurysms model is a key prerequisite for good finite element analysis.,In this paper, we have proposed a good method which could reconstruct the three-dimensional model of cerebral aneurysms quickly and accurately based on CT date.,After the model was treated in CAD software. The IGES file was imported to the CFD-ICEM software to create the boundary (inlet, outlet and wall) and set boundary conditions. Next, we transferred the surface geometry to 3-D volume model and then calculated the volume mesh to generate grids for the CFD simulation。,process,Iges file,fluent file,fluent file,Blood vessel with aneurysms,CT images,Calculating 3D Model in MIMICS,Join surfaces togetherIn CATIA,The 3D model,Cutting branches,
