Recently, there are increasing concerns about the evaluation of vehicles’ safety that frequently refers exclusively to the primary collision during an accident, while neglecting often involved subsequent collisions. Despite theoretical approaches to secondary collisions had already been proposed, they lack sufficient experimental verification as a vehicle’s post-collision motion appears largely unpredictable. The present study avoids the indicated drawbacks and addresses collision experiments performed for various impact positions and wheel rotation of a selected vehicle model. The results are obtained for various conditions, while the essential motion trajectory of struck vehicle is determined based on the movement of the vehicle center of gravity and rotation angle. The monitored translational and angular velocity of ‘struck vehicle’ confirms our claim that the impact position significantly affects primary and secondary impact rotation and moving distance of the vehicle involved in an accident. In sum, we present the accuracy and application range of the automobile motion theory to be validated while based on experimental data.
