Frame deformation
Problem:
~400 wires with 70g on both ends on each wire
will lead to deformation of the frame
-> sagging wires, possible sparkings etc.
-> G10 material is ~1/3 less stiffer than Stesalit.
Some PhD thesis report a frame deformation ~1-2mm
(Stesalit)
with DCs of similar size of Region 3 ...
==> what is the frame deformation using cheap G10 ?
==> how does the deformation depend on the inner/outer frame size
-> define outer frame dimensions
for purchase
-> define pretention of frame for
wire stringing
Approach: study frame deformation with finite element analysis (FEA)
at present: - definition of frame dimensions
and G10 properties (done)
- meshing frame with ~5.000 - 65.000Nodes (done)
- applying external load on frame (static)
FEA test result for a G10 frame deformation
(load exaggerated)
First preliminary results from
FEA
HDC:thickness
= 3mm, border = 150mm
==> max.
simulated deformation: 1.7 mm
VDC: thickness = 13 mm, border
= 150mm
==> max. simulated
deformation: 0.26 mm
