Numerical investigation of car collisions at different speeds in order to find a suitable analytical relationship

The current research aims to simulate the collision of a car at several different speeds in ABAQUS and ANSYS software, to check the results and find the appropriate analytical relationship. For the results of the project to be accurate and reliable, five car models were analyzed in five phases. At first, for each phase of the project, the geometric model of the cars was modeled in an engineering design software, and their various components such as body, chassis, etc. were assembled on each other. After entering the models into ABAQUS or ANSYS software, the geometric defects of the model were repaired. Finally, things such as tension, deformation, energy, etc. were compared and an analytical relationship between energy and collision speed was proposed for the car body by MATLAB software. The results show that the most energy transfer is from the front part of the chassis to the cabin and the front points play a significant role in the accident.
