A Study on New Approach of Optimization for the Automotive Plastic Interior Parts

2015-01-047604/14/2015

Carmakers have tried to lower the vehicle weight for raising fuel efficiency. This trend involves a trade-off with the vehicle stiffness. In automobile interior parts, the thickness has needed to be decreased for the weight reduction but this makes the stiffness worse. A new approach for improving the stiffness due to the weight reduction is required and various optimization methods at early development stage have been introduced currently. However, it is difficult to apply optimization for the interior parts since many interior parts' structures generally depend on the design. But as studying the structure in detail, we discovered some factors that affect the performance without depending on design. The door trim is selected for optimization item because it has many characteristics of automobile interior parts. In our case study, the factors that improve the performance of door trim without changing design are considered as fastener position and flange rib layout. The optimization

2007-01-372208/05/2007

The complete evaluation of the side vehicle structure and occupant protection is only possible by the full-scale side impact crash test. But auto part manufactures, such as door trim makers can't conduct the test especially when the vehicle is under developing process. And important information and components for estimating crash performance is restricted. With the proposed design procedure for the door trim by a simple impact test method was demonstrated to evaluate the abdominal injury. In addition to simple test, Euro-NCAP test result that is conducted by referenced full-scale test in Korea is compared with several test results. In conclusion, this simple test method have similar trend for abdominal injury index so that it is possible to present guidelines of door armrest design to carmaker at the early stages of vehicle program development.

Load Path Considerations for Side Crash Compatibility

2007-01-117604/16/2007

Heavier, larger pickups and SUVs are bound to encounter lighter, smaller passenger vehicles in many future accidents. As the fleet has evolved to include more and more SUVs, their frontal structures are often indistinguishable from pickup fronts. Improvements in geometric compatibility features are crucial to further injury prevention progress in side impact. In corner crashes where modern bullet passenger car (PC) bumpers make appropriate geometrical overlap with target PC rocker panels, concentrated loads sometimes disrupt foam and plastic bumper corners, creating aggressive edges. In situations where sliding occurs along the structural interface, these sharp edges may slice through doors, panels and pillars. End treatments for such bumper beams should be designed to reduce this aggressive potential. The experimental comparison presented here demonstrates that load path compatibility can provide a means by which severe door intrusion due to oblique corner impacts may be reduced

Economic Analysis of Two Different Door Architectures

2001-01-304510/16/2001

In the past, materials selection for automotive components has been managed on a part-by-part basis. As a result, the economics of these selections have often been reduced to comparing material price/property ratios, rather than technological options. More recently, the debate around modular designs and their advantages and disadvantages has shifted the emphasis towards a higher level viewpoint that deals with more complex systems. This approach provides the opportunity to search for new combinations of product architecture and materials that may exploit specific material advantages better than the classic part-by-part replacement. This paper presents the results of an economic analysis for two different door designs. The door designs differ both with regards to their product architectures and with regards to the materials they employ. The economic analysis considers the following process steps: parts fabrication, subassembly, paint, and final assembly (trim) for two production

AUTOMAY01_0305/01/2001

Making new vehicles out of old vehicles-as well as discarded carpeting-enables automakers to do the right thing for the environment society, and their balance statements. In what appears to have been an accurate portent of things to come, 50% of the automotive engineers and designers who planned to attend the SAE 2000 World Congress cited cost reductions as the industry's top concern, up 19% from the previous year. Also, 50% of the survey respondents of the DuPont Automotive/SAE International survey identified cost as the most important quality automakers seek when choosing a supplier. In the year since the survey was conducted-and especially in the past six months-automakers have not been reticent about requesting cost cuts from suppliers; it may not be a stretch to now put those cost-concern figures at 100%. “The focus on cost reduction has reached its highest level in the last six years,” said Walter Fields, Vice President, DuPont Automotive Engineering Materials. “The trend toward

Life cycle costing tool development for design decision

2000-05-021706/12/2000

The objective of this study is to develop a design decision support tool that incorporates life cycle costing including the environmental effects of a system. A life cycle costing that incorporates the effects of the environment is essential to support the design decisions required during today''s product or system developments. Since the international environmental standards (ISO 14000 Series) were issued in the early 1990s, the leading companies in the automotive industry have been developing integrated assessment methodologies. These methodologies attempt to integrate cost, quality, environment and other related areas into the total life cycle assessment of a system. Therefore, it is important to develop a tool that integrates all information concerning the product in the early stages of development. It is also appropriate to support the decision-making in selecting the best design alternatives. The tool can minimize the trade-off between technical performance and cost parameters

All Olefinic Interiors-What Will It Take To Happen?

2000-01-063203/06/2000

TPO is getting wider acceptance for automotive applications. An exterior application like a fascia is a very good example. Interiors are still a challenge due to many reasons including overall system cost. For interior applications, “all-olefin” means it mainly consists of three materials: TPO skin, cross-linked olefinic-based foam and PP substrate. The driving force for TPO in Europe is mainly recyclability while in the USA, it is long-term durability. This paper describes the key limitations of the current TPO systems which are: poor grain retention of TPO skin, shrinkage in-consistency of the skin, high cost of priming (or other treatments) and painting of the skin, lower process window of the semi-crystalline TPO material during thermoforming or In-mold lamination / Low pressure molding, high cost of the foam, low tear strength of the foam for deep draw ratio etc. The paper shows the different ways of manufacturing the all olefinic parts which are: thermoforming over PP substrate

Fabrication of Interior Door Trim Using Ceramic Dies

880341

02/01/1988

To produce high quality appearance interior parts, precise pattern forming or gloss reduction of three-dimensional door trim cover materials are utilized. In the preparation of formed trim cover using polyvinyl chloride (PVC), prior pattern forming on original cover material or post-pattern forming with vacuum forming dies are employed. In the latter case, the die is usually made of epoxy resin. Although vacuum holes are prepared on the resin die as necessary, the lack of uniformity in air permeability causes inferior pattern transferability. In this development, special porous ceramic die is used as die material so that trim cover material can be evenly sucked through the fine pores on its surface. As a result, a door trim forming die of superior pattern transferability has realized. The features of this- die are as follows. 1) The addition of metal powder, metal fiber, and binder to the ceramic powder has achieved well balanced air permeability, compressive strength, and dimensional
