Optimal Design of Panel Reinforcing Material Using Practical Measurement Technique 2005-01-2281

Expandable reinforcing material such as that used for the outer panel of a door has been used to compensate for the lack of stiffness in automotive body panels. This material can improve panel stiffness and reduce vibration that causes radiated noise. Material properties in practical use have generally been evaluated by sensory methods. These properties, however, have not been sufficiently quantified to optimally design reinforcing material. We have developed evaluation methods aimed at ensuring reinforcement and also at reducing vibration and deformation in a panel. By employing these evaluation methods along with simulation of a material's basic properties, we are able to achieve the optimal design of materials for outer body panels.
