Strength Analysis and Safety Design of Baby Car Seat


Article Preview

After the automobile made an emergency brake or bumped by accident, the baby car seat will be deformed and cracked by great force, the baby car seat have became a very important topic for years. This study focuses on analyzing the state of baby car seat after receiving forces, propose the improvement of structure strength and safety factors, enhance the structural strength of baby car seat and improve collision resistance. The internal skeleton was a backbone of baby car seat structural design, this research utilized simulation that combined CAD software (Pro-E) with finite element analysis software (Ansys\Workbench) to analyze the bumping situation, the high-speed camera was also applied to record the bumping situation of baby car seat. The comparison between these two results was used to design the skeleton within safety seat in order to approach the anticipative structure strength. Therefore, structure analysis will enable baby car seat to reach a high level of collision resistance.
