Fatigue phenomena, which appear generally below the yield stress, is the cause of more than 80 % of in-service mechanical failures. However, the optimization of the weight and cost when designing mechanical components or structures, linked to improved performance, leads to increasingly stressed components. Therefore a fatigue design approach must be done by the engineer. This paper shows the ex...

As compared to petroleum diesel, biodiesel is more corrosive for automotive materials. Studies on the characterization of corrosion products of fuel exposed automotive materials are scarce. Automotive fuel system and engine components are made from different ferrous and non-ferrous materials. The present study aims to investigate the corrosion products of different types of automotive materials...

Designing a family of product variants that share some components usually requires a compromise in performance relative to the individually optimized variants due to the commonality constraints. Choosing components for sharing may depend on what performance losses can be tolerated. In this article an optimal design problem is formulated to choose product components to be shared without exceedin...

Many companies in the automotive industry have adopted MDD in their vehicle control software development. As a major automotive company, General Motors has been using a custom-built, domain-specific modeling language, implemented as an internal proprietary metamodel, to meet the modeling needs in its control software development. As AUTOSAR (AUTomotive Open System ARchitecture) is being develop...

The actual unstable environment leads firms to overlap their boundaries and create strategic alliances and collaborations with their suppliers, customers and partners. Our automotive company case is an organization that is applying this concept. As an extended enterprise, it continuously innovates and creates new products using its dynamic capabilities. It seeks to leverage its relationships wi...

Context: Self-Driving cars are getting more and more attention with public demonstration from all important automotive OEMs but also from companies, which do not have a long history in the automotive industry. Fostered by large international competitions in the last decade, several automotive OEMs have already announced to bring this technology to the market around 2020. Objective: Internationa...

This paper describes the need for dynamic (transient) simulation of automotive air conditioning systems, the reasons why such simulations are challenging, and the applicability of a general purpose off-the-shelf thermohydraulic analyzer to answer such challenges. An overview of modeling methods for the basic components are presented, along with relevant approximations and their effect on speed ...

We present HoloMiracle, a system that enables operators of industrial equipment and beyond to pose queries about physical, virtual, regulatory, and functional relationships between components of the equipment and that visualizes the responses to their queries in-situ, as a holographic overlay. We report on HoloMiracle’s system architecture and discuss a concrete use case in the automotive manuf...

The effect of various fuel additives on the ability of platinum-palladium catalytic converters to remove the carbon monoxide and hydrocarbon components of automotive exhaust has been examined. Engine dynamometer studies suggest that these catalysts may be successfully used in conjunction with fuels of relatively high tetraethyllead concentrations, provided the ethylene dibromide portion of the ...
