Effect of Bumper Thickness with Collision Simulation of Passenger Vehicles

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