  • Evaluation of airbag deployment robustness using eigenmode decomposition

抄録

<p>In recent years, demands for robustness in products have increased. Airbags are essential restraint devices that are indispensable for crash safety in automobiles. However, various factors, such as friction, affect their deployment, and deployment repeatability is still an issue, especially in the out-of-position case where contact with the occupant occurs during deployment. In this paper, the results of several Out-of-Position cases with slightly different friction and dummy position are processed using the robustness analysis software DIFFCRASH. As a result, the relationship between input scatters and the modes of behavior are visualized as well as the temporal evolution of the scatter.</p>
