Abstract: The objective 0f this paper is to discuss a number of methods and terminology illustrated for Automotive Design Process considering current environment situations. A brief overview and classification of Automotive Industry as well as Vehicle body Structure. General characteristics, representative examples, integration and information management issues of design automation supporting environmentally conscious product design.

Introduction: Car manufacturers have implemented several technical strategies in order to meet legislation requirements and satisfaction of consumer expectations. Examples of these strategies include mass reduction, improvement in aerodynamics, powertrain efficiency and safety, alternative propulsion systems Lightweight design is particularly investigated by OEMs since it allows consistent reductions in terms of fuel demand and air pollutant emissions. One of the most effective strategies for obtaining mass reduction is the re-design of vehicle parts via material substitution. In this context, a key factor is the material selection phase, along with advancements in materials research and related manufacturing technologies. The material selection needs to balance several antithetical aspects (performances, feasibility, recyclability and environmental sustainability) and this leads to necessarily face controversial issues In particular, innovative lightweight materials (such as composites and biopolymers, hybrid materials, high-strength metal alloys) are considered promising substantial improvements in terms of mass reduction but some aspects regarding their environmental consequences still need to be investigated.

Literature provides several methods for identifying the best alternative within a panel of different lightweight design solutions. Considering the Design-for-Environment, the main capabilities offered by an eco-design tool are the critical comparison of alternative product concepts and the identification of improvement options such as alternative materials/processes But even so, the need for effective tools able to compare and select appropriate materials during an early design phase is still a research field Some authors study the combination of materials selection with structural optimisation, weight minimisation and environmental assessment, with the aim of enhancing a systematic evaluation of material alternatives In other cases, the focus is the assessment and inclusion of specific indicators (e.g. recyclability) or a set of key sustainability indicators along vehicle life cycle. In sustainable product design, such tools should be able to elaborate and integrate different information (technical, environmental and economic) and provide a score system able to support material selection according to a multi-criteria approach. In response to a more comprehensive assessment, the wide variety of parameters is responsible for a higher complexity of the analysis and the necessity of a multi-disciplinary working group (e.g. designer, material specialist, environmental analyst).

In many cases, the LCA methodology is used for the environmental assessment of materials during the concept design.

Although several studies have been carried out on material selection in the product design stage, most of these researches rely on hypothetical case studies, thus not deepening some of the challenges like data exchange and interpretation of results. That said, the contribution of this paper is identifying and discussing the main barriers for the integration of environmental performances within the concept design stage according to a realistic case study. In particular, the research deals with the following specific aspects:

  • integration of environment within the traditional design procedure;
  • exchange of information among expertise and primary data collection;
  • analysis and interpretation of the environmental results.

First a general workflow is presented in which the typical design phases are reported together with technical and environmental validation. Each step is described in detail and all the exchanged data are presented. The developed workflow is then applied to a real case study concerning the lightweighting of a complex component produced by Magneti Marelli® (MM). Therefore, all the workflow steps are discussed according to the case study-specific features. Finally, discussion and conclusions are drawn in order to highlight the potentiality offered by data exchange during the overall design process. The case study also serves to assess feasibility and environmental performance of glass fibre-reinforced polyethylene (PETGF) for an engine component, thus representing an innovative application which could provide insights for further under-hood applications.
