ABSTRACT |
The finite element method is the most common method used to solve engineering and mathematical model
problems. Related solution areas include structural analysis, heat transfer, mass transport and electromagnetic potential. FEM
is a specific numerical method used to solve partial differential equations in two or three space variables. To solve a problem,
FEM breaks up a large system into smaller, simpler parts called finite elements. First, a three-dimensional model of the
system to be analyzed is produced. While defining the model, the materials and connection types found in the model are also
deter-mined. Afterwards, the model is divided into small parts and analyzed under specified conditions. A crash test will be
conducted in this study. For this, the conditions of the vehicle parts will be examined by hitting a wall under the conditions of
which the model design of the vehicle is determined. Crash tests were carried out for two different bumper thicknesses on the
same vehicle and the test results were examined. The vehicle speed is modeled as 20 m/s in the simulation carried out from
the moment of impact until 0.14 seconds later. The effect of buffer thickness on axial displacements at impact and energy
changes are presented. |
