“…The development process itself starts with the Concept Phase, which includes conceptual design of the complete vehicle layout including styling, vehicle packaging and ergonomics, body and component development, and of course the propulsion system. Beginning with initial styling works, the vehicle architecture is built up and all components are integrated [2]. Drivetrain modules are taken over from existing platforms or newly developed, including new technologies, e.g.…”

Electric drive systems consisting of battery, inverter, electric motor and gearbox are applied in hybridor purely electric vehicles. The layout process of such propulsion systems is performed on system level under consideration of various component properties and their interfering characteristics. In addition, different boundary conditions are taken under account, e. g. performance, efficiency, packaging, costs. In this way, the development process of the power train involves a broad range of influencing parameters and periphery conditions and thus represents a multi-dimensional optimization problem. Stateof-the-art development processes of mechatronic systems are usually executed according to the V-model, which represents a fundamental basis for handling the complex interactions of the different disciplines involved. In addition, stage-gate processes and spiral models are applied to deal with the high level of complexity during conception, design and testing. Involving a large number of technical and economic factors, these sequential, recursive processes may lead to suboptimal solutions since the system design processes do not sufficiently consider the complex relations between the different, partially conflicting domains. In this context, the present publication introduces an integrated multi-objective optimization strategy for the effective conception of electric propulsion systems, which involves a holistic consideration of all components and requirements in a multi-objective manner. The system design synthesis is based on component-specific Pareto-optimal designs to handle performance, efficiency, package and costs for given system requirements. The results are displayed as Pareto-fronts of electric power train system designs variants, from which decision makers are able to choose the best suitable solution. In this way, the presented system design approach for the development of electrically driven axles enables a multi-objective optimization considering efficiency, performance, costs and package. It is capable to reduce development time and to improve overall system quality at the same time.

“…The challenge in the development of stone chipping investigation is to approximate the simulation as close as possible to reality, and that during early stages of full-vehicle development. This fact requires a detailed consideration of several deciding factors and their evaluation in terms of relevance and necessity regarding the discretized integration into a simulation, [2], [5], [10], [11].…”

“…Multi-layer coatings are applied since a long time in the automotive industry to enhance stone chipping protection, but a widely used application of the measure increases the production costs. Several studies and investigations are concerned with the resistance of coatings or layers as passive protection against failures caused by stone chipping to optimize the coatings and their application methods, [5], [8], [11]. Simultaneously, there also raises the question whether stone chipping can be actively prevented.…”

Frontloading in product development supports the possibility to make important decisions as soon as possible. The dedication of virtual product development tools implicates cost savings by reduction of physical prototype testing. The present publication treats the potential of computer-aided design (CAD) in a specific application to offer changeable, quick and efficient development. The application of the developed methods and tools is shown for stone chipping investigations, which are important for the definition of corrosion protection measures in automotive body design. The automation by use of modern parametric-associative CAD models in combination with high level of knowledge integration enables the creation of simulation tools, which are able to support development processes especially in early stages.

The process of design, development and production of cars has been strongly influenced by the use of computer technology since the 1980s. The philosophy of CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) approaches has become an integral part of the automotive industry. These technologies have shortened the innovation cycle in car model lines to 6-8 years. In the middle of this cycle, the so-called facelift of the model line is employed, when there are certain shape changes of the exterior and interior of the car or the equipment is expanded with new or improved elements. CAx systems enable changes to be made in such a short period of time. This article deals with the design of a fully parametric CAD model of a car interior element. Specifically, it is part of the door pull handle. The advantages of connecting a fully parametric model to a spreadsheet were pointed out. This link has a significant impact on the speed and flexibility of change processes on product models. The model was created in the Part Design volume modeler in the CAD system CATIA V5 Release21, which is used mainly in the automotive and aerospace industries. The parameters of the model were linked to the MS Excel spreadsheet.
