Finite element analysis of internal door panel of a car by considering natural composites

Abstract

In this paper work the dynamic structural Finite Element Analysis of internal door panel of a vehicle by considering Delonix Regia Seed Shell (DRSS) powder, coconut shell powder, orange peel powder and kneaf fiber composite materials was conducted. The objective of the paper is to develop a suitable model of internal door panel for Toyota DX car, to conduct a transient dynamic structural analysis (stress and deformation analysis) of internal door panel by finite element method, to compare the performance of DRSS powder, coconut shell powder, orange peel powder and kneaf fiber composite materials of internal door panel. The door panel of Toyota Corolla DX model vehicle was used to develop the geometric model of the internal door panel by CATIA V5 R20 modeling software.

This 3-D geometric model was imported to using ANSYS Workbench 14.5. The transient dynamic structural FEA was done after assigning loading and boundary conditions. The applied load considered for this analysis is the self-inertial weight of the panel due to the acceleration field produced while the door is closing. The equivalent stress and the deformation are noted and investigated to compare with the literatures revised. The result shows that, DRSS powder reinforced polyester composite panel has the smallest equivalent stress and deformation values, as compared with the other. Based on these outcomes, it is recommended that DRSS powder reinforced with polyester composite materials are suitable for internal structural automotive panel applications.
