Vehicle Dynamics in Single-Vehicle Accidents - Validation and Extensions of a Computer Simulation

摘要

This report summarized the results of the second year of a program of combined theoretical and experimental research aimed at the development of analytical means of studying the energy conversion characteristics of roadside terrain features and obstacles. The report of the research constitutes one part of a Bureau of Public Roads program aimed at reducing the incidents of injury-producing accidents that occur in collisions between single vehicles and fixed objects on or near the roadway. A computer simulation of the dynamics of single vehicle accidents is validated by means of comparison of the model predictions of vehicle responses with measured results from a series of full-scale experiments. Excellent correlation is achieved for a variety of violent maneuvers, most of which include simultaneous ride and cornering responses. The test procedures and instrumentation of the full-scale experiments are described in detail. (BPR Abstract)
