Analysis on Characteristic Need for Motorcycle Helmet Structures via Product Development Process and FEA

A motorcycle helmet is an essential of safety equipment that shields the head from impact. The goal of the research is to determine whether an existing motorcycle helmet can withstand impacts and to suggest a new design with a greater safety factor. The performance of the motorcycle helmet was identified in this study using Finite Element Analysis (FEA) based on the impact situation. Additionally, by analysing the criteria for material selection specifications and developing design ideas based on user requirements, Quality Function Deployment (QFD) and Theory of Inventive Problem Solving (TRIZ) approaches. The material used in Finite Element Analysis (FEA) for the motorcycle helmet shell is Acrylonitrile butadiene styrene with Polycarbonate (ABS+PC) and Expanded Polystyrene (EPS). Displacement, equivalent stress, and strain are taken into account as output parameters. Based on the findings, it is clear that a motorcycle helmet with a liner is necessary and that it has a substantial impact on FEA. By using the new design helmet structures, it is anticipated that the performance and protection of the helmet will increase by 56.26%, protecting the rider from serious injuries.
