Mechanical behavior analysis of CDIO production-blood vessel robot in curved blood vessel

Abstract

In order to analyze mechanical behavior of blood vessel robot (student's CDIO production) in curved blood, and provide the data for outline design of robot, the flow field out side of robot is numerical simulated. The results show that the vessel shape has significant influent to flow field out side of robot, in curved blood vessel, the wall shear stress (WSS) is greater obviously than that in the straight blood vessel. The radius of blood vessel has influent to WSS, along the radius increases, the WSS on the surface between robot and the inner ring is closer to agreement that of the outer ring gradually. The WSS distribution is also influent by its position in the blood vessel. © 2010 Springer-Verlag Berlin Heidelberg.
