Validation of PC-Crash - A Momentum-Based Accident Reconstruction Program 960885

PC-Crash is a Windows™ - based accident reconstruction program developed in Graz, Austria by Dr. Hermann Steffan. PC-Crash collision analysis results are compared with previously published staged collision data. The program uses 2-D or 3-D vehicle geometry to model the pre-impact dynamics, impact engagement, and post-impact trajectories of multiple vehicles and multiple collisions. Steer angle, braking level, friction, and suspension properties at each wheel can be varied. Simulations can be visualized from any angle with the program's built-in 3-D animator.
The staged collisions were reconstructed using PC-Crash and the trajectories were compared to actual measurements of the skid marks and rest positions. Vehicle speeds were compared to the PC-Crash predicted values.
