GENERAL INFORMATION 1–3
3. BODY SAFETY
Modern stressed-skin bodies are designed so as to have
a sturdy passenger cell protected by front and rear
crumple zones.
• In an accident the crumple zones are designed to
convert impact energy into deformation work.
• The shape, material and metal thickness must all be
precisely matched.
5. USE OF NEW HIGH-QUALITY
MATERIALS
• The requirement for reduced body weight has lead to
a reduction in the amount of steel used, e.g. through
the use of thinner sheet steels.
This has been achieved with HIGH STRENGTH
SHEET STEELS, in spite of the need to meet higher
body strength requirements at the same time.
High strength steels have a tensile strength and a
yield strength as much as 30% higher than conven-
tional steel. These properties must not be destroyed
when carrying out repairs, e.g. by using excessive
heat.
6. CORROSION PROTECTION
• The durability of the bodywork, its associated long-
term safety and retention of value largely depend on
the corrosion protection given to the sheet metal.
Here, DAEWOO takes a great deal of care in pro-
duction.
• Therefore, this corrosion protection must be pre-
served or restored when repairs are carried out.
7. SUMMARY
• All DAEWOO vehicles are built to the highest stan-
dards in terms of styling and material properties.
• These high quality standards must be maintained
when accident repairs are carried out.
• Mistakes made when carrying out repair operations
such as straightening, welding sheet-metal parts, etc.
not only produce visible defects, but may also com-
promise the safety of the vehicle.
• Mistakes made when restoring the corrosion protec-
tion compromise durability.
• Many years of experience, refined computational
methods and expensive series of crash tests mean
that DAEWOO now builds bodies giving optimum de-
formation in the crumple zones in frontal or rear im-
pacts.
When repairing body damage, it is therefore imperative
to restore the original structure and strength in order to
guarantee the safety of the occupants.
4. LOADS ON BODY PARTS
• The earlier practice of making a distinction between
load bearing and non-loading bearing parts of vehicles
with a chassis and body is no longer justified now.
Every part, even the windows, contributes to the over-
all strength of the vehicle.
THEREFORE, WITH MODERN DAEWOO BODIES,
ONE TALKS OF HIGHLY STRESSED AND LESS
HIGHLY STRESSED PARTS.
