Abstract
Side-door impact beam has been introduced to the passenger vehicles to reduce the door intrusion into passenger compartment during side impact collision. This study aims to develop the new bio-inspired design concepts of composites side-door impact beam. The integrated Theory of Inventive Principle – Function Oriented Search (TRIZ-FOS) and Biomimetics method is the idea generation technique applied in this research to develop the design concepts while the analysis of the generated design concepts using impact test simulation in finite element analysis (FEA) is the method to compare their performances. TRIZ (FOS) – Biomimetics method helps to transfer the nature technology into engineering problems and shows that it can generates five design concepts based on three nature technology which is toucan beak, pomelo peel and hedgehog spine in this study. The FEA analysis method then compared their strength, deformation, energy absorption and weight. In a conclusion, the integrated method of TRIZ (FOS) – Biomimetics helps engineers in generating the nature technology ideas to solve engineering problems using a structured method as proposed in this study while the FEA method really helps engineers to obtain the performances data for the design generated before proceed to the next step of product development process.
Highlights
General Motors have introduced automotive side-door impact beam in late 1960’s to prevent the passenger’s compartment area from intrusion during the side impact collision [1]
This study begins with idea generation technique to find the design that can imitate the nature technology into the new design of side-door impact beam
The impactor is made from stainless steel that impact the new side-door impact beam
Summary
General Motors have introduced automotive side-door impact beam in late 1960’s to prevent the passenger’s compartment area from intrusion during the side impact collision [1]. The numbers of fatality reduction are not significant until the National Highway Traffic Safety Administration (NHTSA) improved the regulation [2]. Started in 1990, NHTSA introduced Moving Deformable Barrier (MDB) for the dynamic test of side impact test procedure to improve the side impact test [3]. Car manufacturers believe that the side-door impact beam can Revised Manuscript Received on February 05, 2020.
