The details of similitude modeling of rollover protection structures (ROPS) standard overturn tests requiring development of scale tractor models with features of a full scale tractor relevant to its overturning behavior are reported. The various objectives to be accomplished were: 1) identify the variables pertinent to the problem; 2) develop design conditions for model testing using similitude principles; 3) develop tractor models to experimentally verify modeling of tractor motion during overturn; 4) experimentally verify modeling of ROPS behavior under quasi-static loading; and 5) conduct experimentation to verify this approach to modeling the dynamic deformation of ROPS during overturn. Film analysis verified modeling of the tractor overturning behavior. It was found that ROPS structural modeling was verified by the static and the overturn testing, and it is suggested that this testing be used for evaluation of new designs of the ROPS and to study accident behavior.
