Abstract—This research purpose is to study the energy absorption capability of aluminium honeycomb specifically designed as equipment for reducing the severity of impact force when hit by a car with 1.5 tons of weight while running at the speed of 50 kilometers per hour. The research processes begin with the designing of the honeycomb model using the computer program, then simulating the force of impact acceptance with the finite element method in order to search for the most suitable size and material. Afterward, the prototype was created and tested on force acceptance using the methods of quasi-static test and impact test. The research result illustrates that all the tests — computer simulation, quasi-static test and impact test — are in agreement demonstrating that aluminium honeycomb is capable of absorbing energy within a 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 aluminium as its main material.
