Sensitivity analysis, bending
properties of fly line
Purpose
Method
EI is the product of the Young’s modulus, E, and the second
moment of inertia, I. No direct measurements have been made to determine
EI for the fly line. The sensitivity of the solution to changes in EI
is analyzed:
·
The 50ft
oh cast reference is used as reference, the
solution for this cast is denoted EI flyline 100% (E
as for all calculated casts except the two below).
· A solution, denoted EI flyline
200%, is calculated with a 100% increased Young’s modulus as the
only change in relation to the reference cast.
· A solution, denoted EI flyline 50%,
is calculated with a 50% decreased Young’s modulus as the only change in
relation to the reference cast.
The three solutions are compared in the
animation below (click on image to start animation).
· Changing the bending stiffness +100% and -50%, in relation to
the reference, gives a limited impact on the computed casts.
· It may be concluded that the sensitivity of the solution to
changes in the bending stiffness is comparatively small.
· Note: The monofilament leader is made of materials e.g.,
nylon/polyamide, with known Young’s modulus and need not be analyzed.
