Project definition:
In order to apply paint to the A330, Airbus Industrie needed scaffolding
that would allow them easy access to all parts of the aircraft.
The resulting
structure is suspended to the framework
of the painting
workshop and measures
9 m by 39 m
, with a height of
12 m
and weighs
39 tons
.
Modelling and calculation:
SCIA Engineer made it possible to design the structure according to the
special scaffolding codes
NF12810, NF12811, EN74
as well as to the
Eurocodes
.
We defined the non-linear hinges for the couplers precisely and ran a non-
linear analysis following the iterative
Timoshenko
method.
The model consists of 7,876 nodes, 4,699 beams and 16 non-linear
combinations.
Conclusion:
The challenge was to find
purely geometrical solutions
for the
distribution of loads, as scaffolding elements are standard tubes with a
defined resistance. It was also necessary to take into account
relative
displacements
to avoid any collision risk with the aircraft. Thanks to
SCIA Engineer all of this was possible and straightforward.
