Analysis and simulation of impact tests on automotive elements using two types of high-strength steels

Abstract

This research, the main objective is to study and analyze the behavior of the automobile part called front bumper reinforcement, subjected to impact; For this, two types of materials belonging to the family of ultra-high strength steels will be used, since they are two materials that have excellent mechanical properties. To carry out the studies, a simplified model of said piece was increased; likewise, the analyzes will be developed with the help of CAE software. To carry out the process, a series of stages will be developed, ranging from the development of the model to be analyzed, considering its geometric study characteristics, as well as the knowledge of the mechanical properties of the materials to be worked on. In the same way, the conditions to which the element is subjected at the moment of impact will be known and applied. The force applied to the element will be subject to the speeds according to the standards used for this type of parts in impact tests. This research contributes to the studies of parts that are part of the safety of the vehicle, as well as knowing the mechanical advantages that 38MnB5 steel has compared to 22MnB5 steel.
