A Preliminary Analysis for Design Improvement of Child Car Seat (CCS) Using Finite Element Method (FEM)

Abstract

problems caused by vehicle accidents. Thus child car seat become the most effective and general products just because it can resolve those problems. Child car seat should be safe, sustainable and give comfort to a child. Current child car seat model were designed with fixed concept; that is, no movement or motion between the seat and the base. The purpose of this preliminary analysis is to analyze and improve the design of child car seat focused on sliding concept with swivel and was analyzed to determine the displacement and stress using two types of analysis; linear and non-linear. At the same time, it focused on the new concept of child car seat as a sliding method in the forward facing on the road. In additional, analysis method by finite element analysis (FEA) using Hyperworks software is performed to achieve the objective. Finally, simulation of the analysis results showed the displacement and stress-strain for three cases as linear, non-linear without dummy and non-linear with dummy were proved useful for further development of advanced child car seat.
