Overview
Comparison of profile types
A comparison of the different profile types
highlights the great importance of shaping
on the effectiveness of vehicle body shell
production, and therefore directly on the
number of vehicles produced per day.
The following characteristics distinguish the
Audi Space Frame A8:
- low degree of automation, approx. 20 %
- complex final trimming
- tolerance compensation through cast
joints
- high proportion of curved profiles
The reduction of complex final trimming
improves the relative dimensional accuracy of
the parts, as a result of which the necessary
tolerance compensations can be reduced to a
minimum.
Proportion of curved profiles
straight profiles – 49 %
2-D curved profiles – 34 %
3-D curved profiles – 17 %
The following features distinguish the Audi
Space Frame A2:
- high degree of automation, approx. 85 %
- T-joint at fillet weld produces high-
precision components
- simple final trimming
- laser welding
- only 4 curved profiles
Proportion of curved profiles
straight profiles – 82 %
2-D curved profiles – 9 %
3-D curved profiles – 9 %
