Abstract

This project is about the impact test simulation with different velocity using finite element analysis (FEA) for bumper car. When carrying out the simulation for this project, there are three objectives to be achieved. The first objective is to determine the energy absorbed with different velocity and meshing sizes. Secondly, to correlate the energy absorbed with different velocity and different meshing sizes. Meanwhile, the final objective to be achieved is to compare the simulation results with previous studies. Furthermore, the main problem statement in this project is to study the energy absorption related to different velocities and different meshing sizes to improve the performance of bumper systems during actual collisions. The critical parts involved in this project are the impactor and the bumper system. Hence, the direction and location for each parts during assembly must be correct to avoid obtaining inaccurate results. The entire simulation for impact test is conducted by using the Abaqus software. When results are obtained, graphs of reaction forces against displacement and kinetic energy with internal energy against time are plotted. After plotting the graph for reaction force against time, the area under the graph was calculated in order to obtain the total energy absorbed for the entire simulation by using the software Origin 8.0. Through the results obtained, as the meshing size applied increases, reaction force and energy absorbed decreases. Theoretical approach and comparison with previous studies were also conducted. It was shown that the simulation results have the same graph line trends as the previously conducted studies in terms of reaction force against displacement and energy graphs. Thus, this proves that the results correlates well with each other. Finally, carbon fibre composite, T300/5208 was recommended as a material for future studies as composite materials are gaining more attention in automobiles application.
