Abstract Mainly in the last 30 years so much research has been done on Fe-based calculation of seam welded thin-sheet structures fatigue life. However, available prediction methods have been developed for a limited range of geometries under ideal load conditions. Extrapolating to complex real world geometries and load conditions such those resultant from, for example, ground vehicles dislocation over rough surfaces, are least documented. One example of the application of seam welded thin-sheet structures in the ground vehicle industry is the powertrain installation bracketry. Such brackets are subject to variable amplitude loading sourced from powertrain and road surface irregularities and their fatigue strength is tightly dependent on the strength of their joints. In this paper, a FE-based force/moment method has been used for numerically predicting fatigue life of powertrain installation bracketry of a commercial truck submitted to variable amplitude loading.

Abstract Vehicles manufacturers, in search of cost reduction, fill the tanks of recently manufactured vehicles with the least volume of fuel necessary for future commercialization. The adoption of such practice, depending on the diesel fuel storage conditions, may lead to oxidation products formation in the fuel system and to problems during the first start of these vehicles. Some vehicles manufacturers, trying to minimize the occurrence of these problems, replace the diesel fuel in the vehicle tank with new fuel when vehicle storage time reaches 90 days. As a result of such occurrences, the opportunity for a first fill diesel fuel development, that presented better oxidation stability during storage, was identified.

Abstract The competition among automotive industries increases each year worldwide. Among their diverse needs, what can be highlighted are: market expansion, model diversification, competitive prices, customer-recognized quality, new products release in shorter time periods, among others. The occurrence of flaws that might compromise the health or safety of the product’s user is admittedly one of the largest issues for any manufacturer, especially if these flaws are identified after its commercialization (recall). In this work, a study on recall in the automotive industry in the Brazilian market will be presented, comprising the years of 2013 and 2014. Reasons and causes of recall are addressed, based on the sample of the aforementioned research, with special emphasis on flaws derived from the production process. The conclusion at the end of the work is that the final assembly in the automotive manufacturing process is what requires more attention from engineering area.

Abstract Due to financial global crisis started in 2008 and intensified in the past years in Brazil, the maintenance of a good company’s financial situation is a big challenge and it is more relevant in actual moment. Because of expected turbulent scenario for the next years, it is necessary to adopt strategies to mitigate risks that involve Supply Chain impacting industrial production. In this way, it is crucial adopt strategies and actions that assist to evaluate the performance of suppliers and its associate potential financial risk, what can be considered a companies’ success differential factor during crisis period as well. In this scenario, MWM Motores Diesel adopts an internal process of monitoring the risk of suppliers based on internally developed tools and others available at market.

Abstract Connecting rod joint optimization is a well-known design procedure used for new cranktrains, not only for truck applications, but also for passenger cars. Big end bolted joint is one of the most critical connecting rods regions under engine operation, especially due to joint opening phenomenon and consequent engine failure. Thus, in order to have a robust design, it is usually applied safety factors to absorb this design margin. However, due to the continuous increase of engine loads to attend different emission regulations, this design condition became a vital parameter for connecting rods. thyssenkrupp developed a joint evaluation methodology to be applied during conrod design, presenting better accuracy when compared to the standard development procedure, the VDI 2230 part 1, thus leading to better performance for real engine application. This approach combines the VDI design algorithm with a simple and fast finite element model for force and moment extraction.

Abstract The drag reduction system, commonly used in Formula 1, has as task to reduce the drag force that acts in the vehicle’s airfoils, increasing considerably its speed. When it comes to Formula SAE competition, since the speeds are lower than in F1, the purpose of the DRS can easily become the cooling, despite its name. This paper comes to the development of a drag reduction system applied to the frontal wing whose major objective is to increase the mass flow rate of air through the radiator. Based on a preliminary work supported by computational fluid dynamics, a frontal wing DRS can increase the mass flow rate in approximately 65% at an average velocity of 12 meters per second, which allows the team to use a smaller and lightweight radiator. The challenge was to design a lightweight and reliable automatic system, since it cannot fail nor take away the driver’s attention.

Abstract This paper approaches the use of machine vision as an automation tool for verification tests in automotive Instrument Panel Cluster (IPC). A computer integrated with PXI modular instruments, machine vision software and Integrated Development Environment (IDE) composes the test system. The IPC is verified in closed-loop using the Hardware-in-the-Loop (HiL) technique in which the HiL system simulates all Electronic Control Units (ECUs) that interact with the IPC. Every simulated ECUs signals are sent to the IPC over CAN (Controller Area Network) bus or hardwired I/O using PXI modules integrated with IDE and its responses are captured by cameras. Using machine vision such images are subjected to Digital Image Processing (DIP) techniques as pattern matching, edge detection and Optical Character Recognition (OCR), which can be applied to interpret speedometer, tachometer, fuel gauges, display and warning lights.

France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.

This document establishes standard graphical symbols and color conventions for use in either still (static) or animated graphics used for communicating service information. This document’s purpose is to communicate conventions for using those symbols and colors to accurately and consistently communicate intended information via graphics-based documentation. These practices are intended for use in service procedures, assembly instructions, training materials, and similar applications when trying to minimize the amount of human natural language text used within the document. The still and animated graphical conventions referenced should support effective communication via paper and “traditional” electronic media. The conventions can also extend to documenting via additional electronic delivery paradigms such as Augmented Reality (AR).
