Williamson Forensic Consulting - Specializing in Motor Vehicle Accident Reconstruction

Just as good data form the foundation for a good analysis, good analysis of a collision must be the foundation for any animation.  The animations here were made with the collision analysis program PC-Crash.  PC-Crash is primarily a very powerful analysis tool, but also happens to produce high quality animations.  The animations are therefore true to the original analysis, and obey all of the laws of physics.  This is an important distinction that separates PC-Crash animations from many other animations.

The animations shown below are available in several different formats.  Large frame sizes and higher frame rates result in animation files which are quite large.  For this reason, files here are smaller for easy downloading.  "ZIP" files are compressed the smallest and are an ".exe" file that when run will place the animation on your desktop.
Animation Set 1:  This shows a simple intersection collision.  The first animation is deliberately small for fast downloading, but could be rendered to be much larger and finer.  The left turning vehicle is struck on the right front, rotating the vehicle counter clockwise. The occupant models have been generated with the software MADYMO within PC-Crash.  For the unbelted case, the occupant dynamics near the end with the lack of a right front seat are of course not accurate, but the purpose of the occupant animations are to show the initial vehicle interior contact.
