STRUCTURAL DAMAGE ANALYSIS
What are the 2 types of conventional frame designs? - ANS-Ladder frame and perimeter frame
Ladder Frame - ANS-2 relatively straight side rails with several crossmembers, found in pickups
and some full sized vans
Perimeter Frame - ANS-2 rails that step out at the passenger compartment or center section.
When did the Unitized body style become popular? - ANS-1970's
Unitized structure consists of? - ANS-Assembly of relatively thin, lightweight metals welded to a
sub frame.
Stub Frame - ANS-Combination of a shortened conventional frame front section bolted to the
cowl and floor area of a unitized structure.
Collision Theory - ANS-is the analysis of the forces involved in collision repair
Center Section - ANS-Flat, rigid, passenger compartment area determined by the rocker panels.
Collapse - ANS-The physical shortening or narrowing of any part of the vehicle structure as a
result of collision damage
Collision - ANS-Two forces striking one another
Deflection of Forces - ANS-The redirecting of collision forces caused by the design of the
vehicle or its direction of travel in relation to the object it strikes
Direction of Travel - ANS-The direction the vehicle is traveling at the time of the collision in
relation to the object it strikes.
End Section - ANS-The front or rear sections of the vehicle
External force - ANS-The force exerted by the other vehicle or object involved in a collision
Force during collision damage - ANS-The pressure one object exerts on another
Front section - ANS-The area of the vehicle from the cowl forward
Impact Side - ANS-The side of the vehicle where the collision occurs
