Abstract

Assessing dent resistance is crucial in automotive panel design. It is a key property to evaluate in terms of accurately predicting the panel’s durability. The FEM simulation method is a reliable approach to investigating and predicting dent resistance, as well as for the sound prediction of the automotive exterior closure panels. This whitepaper explores oil canning testing and how it relates to the prediction of dent resistance and buckling load performance of the outer panel for prescribed load conditions. It also analyzes the implications of the oil canning behavior during the pre-program design of automotive assemblies.

Introduction

Automotive closures and dent resistance: Objective

An FEM simulation method is used to investigate in order to predict dent resistance and sound prediction of automotive exterior closure panels. Dent resistance in the automotive panel design is a key propey to evaluate its ability to accurately predict the panel’s durability. Stiffness and dent resistance has a correlation in the design of door, hood and roof outer panels, influencing the aesthetic quality of the vehicle and consequently customer satisfaction.
