Effects of impact direction on energy absorption capability of aluminum honeycomb for road construction zone

Abstract

This work studies the energy absorption capability of an aluminum honeycomb for road construction zone specifically designed as equipment for reducing severity of impact force. The design is considered when it is hit by a 1.5-ton car while running at the speed of 50 kilometers per hour. The research processes begin with the designing of honeycomb model using computer program, then simulating the force of impact acceptance with finite element method in order to search for the most suitable size and material. Afterwards, the prototype was created and tested on force acceptance using the methods of quasi-static test. The results illustrate that the aluminum honeycomb is capable of absorbing energy within designated condition of receiving force in the specified direction. The result will definitely be beneficial for the development of impact force severity reduction equipment that utilizes honeycomb aluminum as its main material.
