Abstract

The goal of this work is to reduce the degree of damage to the passenger car caused by automobile collisions. Bumpers are protective parts installed on the front and rear of automobiles. It can be made of steel aluminum or light weight plastic material. The primary aim of the study is to investigate the energy absorption of the bumper beam. European car bumpers made of aluminum and plastic have been tested to determine the energy absorption. Three specimens from each material were cut in the same shape but with different widths of 20rnm, 40rnm, and 80mm. The investigation was carried out in three different . stages, namely, the experiment using the Universal Testing Machine (UTM); a theoretical approach to the shape of the specimen assumes that the specimens were semi-hexagonal and semi-circle using an expression to calculate the deformation and energy absorption. The study has found that aluminum material absorbs more energy with less deformation compared to the plastic material. The study concludes that large width of 80rnm absorbs more energy and less deformation than 40mm and 20mm of the same material. The large area of contact with the applied load increases the energy absorption capacity of the material. The theoretical approach shows that the result is more similar to semi-circle shape so that the shape of the test specimen is close to the semi-circle.
