Collision speed: detailed analysis of structural and mechanical deformation energy in a car and a motorcycle

Abstract

In this work, a detailed assessment of the structural and mechanical deformation energies caused by a traffic accident, involving a motorcycle and the passenger vehicle is carried out, with the objective of estimating the collision speed. Were, also verified vector orientations, braking marks and occupant launch projection for further comparative analysis with the photogrammetric method of estimating displacement speed. Finally, with the velocity values thus obtained, we compare with the result photogrammetric was performed. Thus, for the type of accident on the screen, we concluded that the best method of estimating the collision speed involving a car and a motorcycle was the combination between the method of reduction between axles and the method of mechanical deformations, resulting in the best approximation in relation to the photogrammetric result reaching 93% approximation to the photogrammetric result obtained.
