Structural and Dynamic Problems in Car Body Design

, 2013
The body of a vehicle is a very complex structure. Usually, it consists of thin-walled beams, characterized by an appropriate section shape, and thin shells properly drawn in order to obtain the selected body shape. As an example of a recent car body it includes: body frame structure, panels, lateral doors, back door, and motor compartment hood.

Conceptual Design for the Structure of Electric Car Body

Advanced Materials Research, 2012
In this paper, ANSYS software is applied to determine the material distribution, load transfer path and equivalent sectional dimensions of the conceptual car body model based on the original body shape of engine cars. In terms of the finite element model of the body, the topology optimization is carried out according to the maximum bending and torsion ...

Car body structure

The Journal of the Acoustical Society of America, 2009
The invention provides a railway car with superior riding quality by improving the flexural rigidity of the car body structure while suppressing increase of body structure mass. A reinforcing plate (7) is attached to a roof construction (1) on the side facing an inner side of the car body at a longitudinal center portion of a railway car body structure

Multi-Objective Optimization of a Car Body Structure

SAE International Journal of Passenger Cars - Mechanical Systems, 2012
<div class="section abstract"><div class="htmlview paragraph">In the last years engineers have to deal with multiple, often conflicting targets, where improvement of one quantity leads to deterioration of others, therefore it is impossible to obtain simultaneous structure enhancements without automatic optimizations tools.

Structural Plastic Inserts in the Car Body

ATZautotechnology, 2008
The reinforcement of the car body by means of plastic inserts can only achieve its full potential when this is considered at an early stage in the design process. In order to design such plastic inserts, it is absolutely necessary to look at the overall system consisting of metal, plastic and structural foam. Therefore in addition to the materials BASF

A Study of Car Body Structure to Reduce Environmental Burdens

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">In the initial design stage, it is important to discuss what kind of body concept is effective from a viewpoint of environment burden reduction. This paper describes the importance of both weight reduction and recycling through conducting LCA (Life Cycle Assessment) for four kinds of body structures.

The Analysis and Improvement for Side Impact of Car Body Structure

Applied Mechanics and Materials, 2013
Based on the finite element (FE) model and Moving Deformable barrier (MDB) model of a car side impact, the virtual test of the side impact was conducted with HYPERWORK software according to Euro-NCAP regulation. Then the impact performance was evaluated in both deformation and response curve of the car body, and the problem of the crashworthiness in ...
