Abstract
The main objective of this work was to develop a methodology for optimising the hood assembly for minimal deformation with robust and homogeneous impact behaviour in a pedestrian head impact. In practice, the design of the outer and inner hood panels must meet all general design requirements in addition to pedestrian head impact performance.
This study utilised Computer Aided Engineering (CAE) simulation tools to investigate the optimal solution for hood panels with consideration to material, panel thickness and geometry of inner hood.
Findings from this study showed that efficiency can be improved with optimal combined thickness of inner and outer hood panels. However, similar efficiencies were achieved for various combinations of thinner inner and thicker outer hood panels.
An optimal pedestrian head impact performance can be achieved with the following design parameters for aluminium hood panels: multi-cone structure for inner hood, and approximately 2.1 mm combined thickness with thinner inner and thicker outer hood combination.
