About the job
We are designing a motorcycle helmet for which an FEA analysis is required in the near future. Details on the subject are given below.
Summary of Key Aspects for FEA (Impact) Analysis of Motorcycle Helmets:
Impact Loads: Include the speed (20-80 km/h), angle (frontal, lateral, rear), and impact points (top, side, chin).
Contact Conditions: Model the impact against surfaces like asphalt or concrete, and simulate realistic friction and sliding behaviors between the helmet and the surface.
Materials: Specify materials such as polycarbonate, fiberglass, or carbon composites, including properties like elastic modulus, impact resistance, and behavior under dynamic loads. Also consider the inner foam (EPS).
Real-World Simulation: Factor in ambient temperature and the behavior of the helmet on different surfaces, simulating its performance under dynamic loads.
Mesh: Use a refined mesh, especially in areas with high deformation, ensuring adequate density to represent the geometry accurately.
Required Results: Include stress/strain distribution, potential failure points, absorbed energy, displacement values, and effectiveness in mitigating the impact.
Iterations and Optimization: If initial results are unsatisfactory, iterate and optimize the design (reinforcements, foam adjustments) to improve performance.
Delivery Timeline: Specify the time for completing the analysis, e.g., [X weeks], and include a detailed report with results and recommendations.

Technical Report: Provide a comprehensive report with results, visual data (charts/tables), and actionable recommendations for improving the design.
Confidentiality: A non-disclosure agreement (NDA) should be signed to protect confidential information.
Software Requirements: Use recognized FEA software like ANSYS, Abaqus, Nastran, LS-DYNA, capable of simulating nonlinear materials, contact, and large deformations. read less
