Manufacturers looking for new ideas to help them bring a design
to production can benefit from coming to Exponent's TEC. Whether
it's a new way of analyzing the design, or a unique test methodology
that ultimately helps them over their design obstacle, we have
expertise they can rely on.
 Fuel
Tank Mounting Strap
The manufacturer of a new light truck discovered a fuel
tank retention problem during a pre-production frontal crash
test. TEC engineers worked with the manufacturer to design
a sled test fixture and test matrix for evaluating design
modifications to the tank mounting hardware. The greatest
challenge associated with this project was the generation
of a sled pulse representative of the crash test pulse, which
contained a short-duration acceleration level well over 100g
near the beginning of the pulse. The sled pulse was achieved
by using aluminum honeycomb mounted on a structure that moved
into our wire-bending decelerator only after failure of special
shear pins tuned to the high g level. After exposing the most
promising hardware modification to this representative pulse,
the manufacturer felt confident proceding to a full-scale
crash test with the new design.
Conversion Van Restraint System
A van conversion company initially came to us to conduct
FMVSS 208 frontal barrier crash testing on several of
their new designs. However, when one of their designs
failed to meet all of the occupant injury criteria, we
were then enlisted to advise them on relocating the anchors
and D-rings of their occupant restraint systems. This
redesign effort led to successful completion of a repeat
FMVSS 208 test as well as FMVSS 207/210 static seat and
belt loading tests. |
