• Description:
  A mathematical model that would simulate tractor dynamics at the time of impact of the roll/over protection system (ROPS) frame with the soil was developed. The model of tractor motion which was developed was able to predict the velocity, positions and energies of the tractor system throughout a complete overturn of the tractor. The model was usable for the condition of a tractor traveling over an embankment or on the ASAE standard S306.3 overturn test course. Data were gathered from accidental overturns and the position of the tractor, and energy in the system at the time of the ROPS impact were established. Interactive computer graphics displays of the motion and ROPS impact were developed. The computer simulation was verified in model studies. Other objectives of the research were to develop a similitude analysis of tractor and soil interaction during the roll/over of a tractor to the rear and to the side, to conduct scale model studies and measurements to verify the similitude analysis of the behavior of the tractor/ROPS system as it impacts the soil, to conduct a similitude analysis of the performance of a ROPS on an agricultural tractor when subjected to a pendulum test, and to model the pendulum impact test and verify the similitude analysis by experimental measurements on at least two different size models, and to specify a test procedure for ROPS which incorporates modeling and test results to predict the performance of ROPS.
