DFMA’s practical contributions to the civil vehicle armoring process: a systematic literature review

2022-02-04
2021-36-0017
The increasing rates of violence and the lack of effective public security policies, especially in large urban areas in developing countries, have reflected directly in the automotive civil armor market, making Brazil the world leader in the segment of ballistic protection type III-A level against handguns according to the NIJ 0108.01 standard [1], followed by Mexico. Faced with this scenario, to speed up the armoring process on brand new automobiles, the armoring companies have adopted shop floor procedures to quickly assembly the ballistic protection parts, without considering automotive design engineering and manufacturing criteria of the vehicle. One of the solutions for improving the quality of this process and optimizing costs is the adoption of the DFMA® tool, Design for Manufacturing and Assembly.

Automotive industries are undergoing a transformation of their manufacturing systems. Called by the German government as Industrie 4.0, this transformation is based on the evolution of traditional Embedded Systems-ES to Cyber-Physical Systems-CPS. In the next years such evolution will have to reach transitory stages, where ES and CPS should coexist for a determined period of time (ES-CPS). Based on this projection, this work compares ES with CPS, identifies the main differences between these systems and thus forms a transitory stage of automotive manufacturing for the next years. The work is structured as follows: Introduction section places the reader on the treated subject and presents the methodology of the work. Later, Industrie 4.0, Embedded Systems (ES) and Cyber-Physical systems (CPS) are defined. Once this is done, the analysis of ES-CPS transition is finished.

Proposal of Technical Interface among Product Engineering, Manufacturing Engineering and Production Engineering, as an Aid to Automotive Product Development Process

2012-10-02
2012-36-0577
Concurrent engineering principles have been almost universally adopted as the ideal solution to the reduction in time for products development. Even with concurrency practice, the lack of interaction among the professionals is still present in some stages of the product development process (PDP). This lack of interaction, or gap, may be observed in the three macro-phases of PDP: macro-phase of product strategy (PS); macro-phase of product and process development (PPD); macro-phase of production and continuous improvement (PCI). The present work aims to propose a methodology, denominated Technical Interface (TI), as an aid to automotive product development process (Automotive-PDP). This methodology can contribute to the engineering departments in charge of PS; PPD and PCI for the update and preservation of technical information about product; process, and production, during all the Automotive-PDP.

2007-01-2705
The vacuum forming process for plastic parts is used to manufacture packages as well as any kind of industrial appliance for a range of sectors, including the automotive industry. This diversity of uses is due to the attractive cost of the process. In the automotive industry, it is a big ally, used as an alternative process in the manufacture of prototype parts. This occurs not only because of the reduction in the time to obtain the part, but also the technical opportunity of product development allowed by this process due to the material that can be used. Some analyses and developments would not be possible if the part were manufactured using the material specified by the part design. This paper shows how the vacuum forming process can facilitate the development of automotive vehicles, as well as a simple and fast way to manufacture vacuum formed parts, which allows parts to be obtained by any kind of industry.

2007-01-2575
Competition among car makers increases each day, as such companies look forward to launching new vehicle models which meet the different consumer niche. As a result, developing different vehicles simultaneously is a market requirement, and doing so might lead to increased production costs in case no appropriate developing and launching strategy is applied. Upon this scenario, the platform strategy has been a practice among car makers for decades and has promoted both standardization and reuse of vehicle components and systems. The most recent global architecture strategy has been used by some of the world car makers, combining communization and standardization to increased flexibility if compared to the conventional platform, which represents a higher number of derivative vehicles as well. The objective of this work is to identify the relevant variables taken into consideration when selecting an appropriate strategy for developing a new global vehicle.

2004-01-3308
The existent competitiveness in the automobile industry has been taking their manufacturers to an incessant search for methods and processes that seek the production of vehicles with quality and accessible costs to their costumers. The Vehicle Development Process (VDP) became an essential element for the success of a vehicle in the market, because the companies found out that, when concentrating their efforts during the development phase, the opportunities for product improvement will be much less onerous when compared with the costs spent when the vehicle are already in production. On the other hand, those improvement opportunities are evidently more difficult of be pointed during VDP than when the vehicle is already in production. This article aims to evaluate how the Design for Six Sigma (DFSS) methodology can be applied to the vehicle development process in order to provide significant results in terms of quality improvement, cost optimization and reduction of development timing.
