Provided the load platform is moving slowly (and dynamics can be discounted)
the main issue is the load-sharing ability of the systems and suspensions.
Often this is complicated by the hysterisis in the systems - e. g. a beam
system does not distribute its loads according to simple statics, because of
friction in the joints. As an example, a different load will occur depending
on the direction of travel of the platform. For slow moving loads, most
modern pavement models can predict permanent deformaaaaation.
