Modeling The Frontal Collison In Vehicles And Determining The Degree Of Injury On The Driver

Abstract

The present research study aims at analysing the kinematic and the dynamic behaviour of the vehicle’s driver in a frontal collision. Hence, a subsequent objective of the research paper is to establish the degree of injury suffered by the driver. Therefore, in order to achieve the objectives set, first, we had to define the type of the dummy placed in the position of the driver, and then to design the three-element assembly, i.e. the chair-steering wheel-dashboard assembly. Based on this model, the following step focused on the positioning of the dummy, which has also integrated the defining of the contacts between the components of the dummy and the seat elements. Seeking to model such a behaviour that would highly accurately reflect the driver’s movements in a frontal collision, passive safety systems have also been defined and simulated, namely the seatbelt and the frontal airbag.
