Due to the increase in car production around the world and the interest of people in using personal vehicles, car and road safety has been one of the major concerns for automakers. Various standards have been developed for vehicle and passenger safety and vehicle accident tests, Among the most widely used standards, one can refer to the Federal Standard of the United States, FVMSS. This standard is a car accident test under various conditions such as rigid or flexible walls, as well as different speeds and occupants of the passenger. Other standards have been set up to Collision with the pedestrian, which, in addition to the requirements for testing, has also been designed to measure the amount of force and acceleration exerted by pedestrians. On the other hand, due to the cost of performing practical and laboratory tests, the evaluation of safety and strength of the vehicle by simulation in the computer has been considered. In this project, an energy absorber model for the first car component is introduced after the car bumper face, and then the absorber with five design variables and twelve Constraint by two optimization method in the MATLAB software to optimize the energy absorption. Continuing to carry out a Federal Standard of the United States crash test, this absorber is added to a car called the Mini-Iranian, and Other components needed for car bumper that have high crashworthiness properties are also modeled on the CATIA software and added to the car model for simulation of the crash test based on the FVMSS standard. In addition, the car with the proposed car bumper in the LS-DYNA finite element software is a simulation of the car and pedestrian accident test by defining the standard accident test conditions. Finally, the simulation results of the accident test, along with the amount of energy absorbed by the components, are examined and the results are verified.
