Side panel of B-Class body in white vehicle design and side crash finite element simulation

Target function in vehicle crash, is about the suitable deformation of vehicle body structure in the case of do not harm occupant’s space. As a consequence the vehicle body structure should be deformed to absorb the impact’s energy and decrease the transmitted forces to occupants. In this paper at design process the vehicle’s body in white has been simulated in CATIA software firstly, and then the element has been created by the Hyper mesh pre-processor software and finally in Pam Crash software, after introducing appropriate materials, standards joints and contacts between vehicle’s parts, and then loads has been created by initial velocity for able to deform barrier toward side panel of vehicle. The vehicle body structure is designed in Vehicle Research Center, based on the style of B-class vehicle platform’s product and the analysis results of this paper is part of new product development process of national platform’s project. As a result, the requirements out puts such as displacement, velocity, acceleration, and energy absorption and section forces have been extracted. After all the results has been compared with the targets which are predicted. Then the suitable thickness for B-pillar illustrated based on the out puts which are extracted.
