autobody 10
unibody - ANS-is a single structure built with the drivetrain, streeing, and suspension parts
mounted directly to the body structure
space frame vehicle - ANS-less dependant on outerbody panels for strucure
body-over frame - ANS-may have a separate unitized structure bolted to the frame
perimeter frame - ANS-have a box type rail design
ladder frame - ANS-have a c channel rail design
ladder frame - ANS-typically used for busses, recreational vehicles, and semi trucks
modern frame design - ANS-a cobination of both ladder type and perimeter type frames, and
uses hydroformed rails
parts of a unitized frame - ANS-upper and lower front rails, radiator core support, strut towers,
aprons, A,B,C,D-pillars, rocker panels, quater panels, rear rails
types of steel - ANS-mild steel, high-strentgh steel, ultra high-strength steel
tensile strength - ANS-maximum force or pressure a material can withstand before breaking
MPa - ANS-mega pascals
total elengation - ANS-how much a material can stretch before breaking
mild steel - ANS-easily formed, may be used for structural parts, can increase in strength when
work hardened, less sensitive to applications of heat.
high strength steel - ANS-HHS
high strength steel - ANS-has a higher strength than mild steel, more heat sensitive, usually
straitened cold, used in thinner gauges
Ultra - high - strength steel - ANS-gains strength from being heat treated, strength is destroyed
when heated, usually replaced when damaged
temperature indicators - ANS-used to help a technician determine the temperature of a part
when it is being heated
