Design and development of components within the structure to be effective and safe. To reduce the risk of accidents caused by the impact or collision. Which has resulted in injury and loss of life, injury to the user's vehicle. Therefore, I will try to find pieces that can reduce damage from impact or collision of the structure. The so-called "self-absorption" into the structure in order to absorb energy, absorbs energy from the collision or action insertion and reduce damage to the main structure to minimize the loses in lives and property assets Jersey. accidents caused by collision or action insert. The variables that affect the ability to absorb the energy of an energy absorbing material such as shape, size, thickness and behavioral damage. Etc.
to carry gold is aimed at determining the energy absorption of the pipe walls, a tubular aluminum filler foam give Polyurethane under Torque (Torsion) using simulation in Abacus. and compared to the actual experimental work. The cross-sectional shape of the pipe at the trial, including the rectangular shape probe. Hexagonal cross-sectional shape The octagonal shape probe And a circular cross-sectional shape The density of the foam test is 50kg / m¬3,75kg / m3,100kg / m3. The analysis found that under torque. The circular pipe cross-sectional shape to absorb energy, the highest status a pipe shape of an octagon. Hexagonal cross-sectional shape The rectangular tubular shape and each has the power to absorb a minimum. The analysis of the density of the foam used to fill the pipeline. 50kg / m-3,75kg / m3,100kg / m3. The density of the foam pipe, aluminum is the optimum energy absorption is 100kg / m3 and a high density foam will absorb higher energy costs.
