Ground pressure per wheel set?
Ground pressure per wheel set?
(OP)
I am looking for either guidance or a formula for calculating ground pressure per wheel set for a truck and trailer that has a capacity up to 80,000 lbs. The tandem axle capacity for both front and rear is 34,000 lbs each and the capacity for the front steering axle is 12,000 lbs. Thank you.





RE: Ground pressure per wheel set?
The suspension design in the tandem axles is normally designed to evenly distribute the load between the two axles, and the side-to-side distribution is the operator's responsibility to load the truck correctly, and a good many transport trailers have the ability for the trailer's tandem axle to be shifted fore/aft to get the weight distribution right, in addition to the operator's responsibility to load the truck correctly.

Don't overlook lateral load transfer due to cornering and longitudinal load distribution due to braking or acceleration.

It smells like they don't know the difference between pressure and force.
