Abstract

A side collision reconstruction algorithm using a database based on the deformed shape information from experiments is suggested. A deformation index related to the deformed shape is developed to set the database for the side collision reconstruction algorithm. Two small-sized model cars are developed to carry out the side collision test. Several side collision tests according to velocities and collision angles are performed for establishing side collision database. A high speed camera with 1000fps is used to capture the motion of the car. Side collision reconstruction algorithm is developed and applied to find the collision conditions before the accident occurred. Several collision cases are tested to validate the database and the algorithm. A database from computer simulation is verified with experiments. According to comparing errors between simulation and experiment, it is satisfied within 6.6%.
