Improvement of structure design and parts within the structure, efficiency and safety. To reduce the risk of accidents caused by action Insert or ramming, which resulted in the injury and loss of life of the people using the vehicle. So designers have to experiment to find the parts that have the ability to reduce damage from shock, called "energy absorber" to be used in the structure by a variable that affects the ability to absorb the energy of the energy-absorbing material type, thickness, shape, include the size and behavior of the damage, etc. In this experiment the objective is to find the ability to absorb the energy of the ore, which is a thin aluminum tube bitch fill, foam polyurethane, pour under torsion (Torsion). Using simulation in the abacus program and experimental piece of work for comparison. By the shape of the pipe trials include shape. cutter shape rectangle tat Hexagon. TAT shape, octagonal shape and cut a circle using the foam density experiment is 50 kg/m3, 75kg/3, m¬ 100kg/m3. From the analysis under torque finds pipe shape. cutter circle to absorb the maximum power is inferior to pipe shape tat Octagon. Hexagonal cut shapes and tubular shape, rectangle to TAT absorbs the least amount of power. From an analysis of density foam used in pipe 50kg/m 75kg/m3, ¬, 100kg/m3 density foam that makes aluminum pipes to absorb Suez energy that is in the 100 kg/m 3 and found a high density foam to absorb energy costs higher.
