Computer graphics displays of simulated automobile dynamics

Abstract

Simulation of physical systems using digital computers has been accomplished by many people over the past few years. One such simulation program at Cornell Aeronautical Laboratory, Inc. constitutes an analytical representation of an automobile as it departs from the highway under various environmental conditions, especially under adverse ones where there is danger of collision with obstacles. As with most complex simulation programs where there are interactions among many components, the equations of motion, including the required restraints, become long and numerous. But foremost, the output data set in printed form is quite extensive and very difficult for the investigating engineer to completely comprehend. About thirty crowded pages of output are printed for a five second automobile test run.
