This paper describes and demonstrates a process for adaptive refinement of quadrilateral curved shell meshes using error estimates from MSC.Nastran. The meshes have been generated originally using Unigraphics'(UG) Scenario application. Although refinement procedures for finite element meshes have been in use for many years, automated procedures have most generally been developed for triangular ...

In this paper we describe the advantages of a model-based approach to embedded component middleware. Component infrastructures such as Enterprise JavaBeans, Microsoft’s COM+ and CORBA Components have become a de-facto standard for enterprise applications. Reasons for this success are the clean separation of technical and functional concerns, COTS containers (applications servers), and the resul...

The usage of advanced high strength steels (AHSS) in structural automotive components has been broadened in the past few years to satisfy the strict specifications of the automotive industry. Besides showing excellent strength to weight rations, AHSS have several limitations due to the high loads required in cold forming and cutting tools, which decrease considerably the tooling performances. T...

Theoretical models play an important role in the design of engine control and diagnostic systems, allowing to reduce development time and costs. The paper describes a control-oriented theoretical model for the simulation of an automotive Diesel engine built up using a “simulation library” developed in Simulink environment. Library blocks, defined for engine components and subsystems, were assem...

The National Automotive Center (NAC) Ground Vehicle Simulation Laboratory (GVSL) is developing and applying engineering simulators and simulations for the evaluation of ground vehicles during all stages of a weapon system’s life cycle research, development, and procurement of new systems; technology insertion and modifications to fielded systems; and trouble-shooting activities arising from tes...

The automotive industry is one of the most important economic sectors in world. At beginning, vehicles only had mechanical components, so use an wire harness was not indispensable. Cars today are equipped with electronic components that, addition to basic operations moving, turning, and stopping, perform more functions every day. Wiring harnesses indispensable for controlling these components. ...

this article aims at strategic vision to technology and suggests a strategic planning for this purpose. the main emphasis in this article is on strategic report compilation in the framework of strategic vision and covers issues such as identification of strategic planning dimensions and strategic vision levels, technology priority setting, environment monitoring, focus on costumer needs, method...

This chapter describes DySCAS: an advanced autonomic platform-independent middleware framework for automotive embedded systems. The concepts and architecture are motivated and described in detail, focusing on the need for, and achievement of, high flexibility and automatic run-time reconfiguration. The design of the middleware is positioned with respect to the way it overcomes the specific tech...

An expert system for material selection for design of automotive component with fibre reinforced plastic materials has been developed. The expert-system shell KEE (Knowledge Engineering Environment) provides a tool to store and process expert knowledge. The system concentrates on selecting suitable materials for automotive components, in particular for major elements of pedal box system namely ...

Due to market demands and technological progress automotive electronic systems have become highly complex, distributed, and heterogeneous systems. In consequence, costs and time-to-market tend to out-grow spendable budgets, whereas quality seriously suffers. To overcome this situation, automotive manufacturers agreed upon a new standard for their electronic systems—AUTOSAR. In AUTOSAR applicati...
