Rollover of Heavy Vehicles 785051

Report outlines studies into the heavy duty vehicles rollover, particularly those transporting flammable or hazardous materials. Studies looked into~

~frequency of overturning.

~types of vehicles involved.

~analysis of accident development.

~interest in improving resistance to overturning.

Data shows that of the accidents studied 26% of the vehicles overturned prior to an impact or to leaving the road. Of these 19% skidded or were involved in an evasive maneuver.

The study explores the influence of the following on rollover:

~ dual wheels vs. single.

~ anti-roll bars.

~ height of trailer center of gravity.

~ longitudinal position of trailer center of gravity.

~ height of the fifth wheel saddle.

~ vehicle braking.

Mathematical models were developed for analysis and further study.
