Wherein L
rBto equal before the elongation of 26 ' distance of longitudinally L between 26 ' a and 26 ' b.
Each finite element node of first connecting portion 26 ' is all subject to corresponding to the vertical shift according to the lengthwise position of the node of above-mentioned equation 1.Remaining five degree of freedom of each node except being positioned at the node at 26 ' a place are all locked.
Therefore, the displacement of the generation of catheterization table 22 utilizes finite element analysis software to determine.
Fore-and-aft distance L between the node at first and second longitudinal end 48,50 places
s2determined after above-mentioned displacement at the first connecting portion 26 '.If but FEM (finite element) model comprises be positioned at first and second longitudinal end 48 and 50 places separately the multiple nodes being positioned at different vertical positions, then the mean place of these nodes of each end is used to determine the distance value L between first and second longitudinal ends 48,50
