Auto Accident Reconstruction Methodology - A four step process
- Damage Analysis - What bent or broke
or became pieces? Careful measurement of the significant structural damage can
reveal the direction and energy of the collision. Matching the areas of contact
may help determine if the brakes were being applied at the time of collision,
and in cases of multiple vehicle collisions, the order of the collisions.
- Motion Analysis - How did the pieces
become bent or broken? TEST, Inc. will determine many factors that have
contributed to the cause, severity and circumstances leading up to an auto
accident. By taking into account evidence from Damage Analysis, and things like
seatbelt condition, skid marks, the airbag module data, and material properties
we are able to accurately determine direction, speed change (Delta V), speed at
time of impact, and deceleration.
- Occupant Motion Analysis - Once the motion of
the vehicle is understood and the condition of the restraint systems (seat belt
and airbags) then, the engineer turns his attention to the motion of the people
inside the vehicle. Again, he is determining speed change (Delta V) and motion
of the parts of the body and impact with interior of the vehicle.
- Injury Potential - The parts of the
human body are made with materials that have been studied to determine their
yield strength (strain), ultimate strength (sprain) and fracture limits. Using
data from the accident, the engineer can determine probability of injury based
on foundation with the specifics of the motion analysis.
