Analysis Of Energy Absorption In Crash Box With Variation Of Trigger Hole Cyrcle Model Using Experimental Tests

Abstract

Traffic accidents kill people every day and a large number of people are injured or killed in car accidents, safety in the automotive industry is being researched extensively. Every year, more than 1.2 million people are killed and ten million are injured in traffic accidents worldwide. Crash boxes as passive safety in vehicles continue to be modified to increase their ability to absorb energy. In this research, 3 crash box models were designed with a frusta model using Aluminum AA 6061-T4. Modeling was carried out using Solidwork software and testing using a Universal Testing Machine. From Experimental test results show that the Frusta 1 hole model crash box has the largest energy absorption capacity compared to other models, 1132.8 J with a force of 118 kN at a displacement of 28.32 mm. This shows that providing the Frusta model with a hole as a trigger provides an increase in the crash box's ability to absorb energy.
