“…Numerous strategies for achieving virtual product development already exist and are extensively described in the literature. Fundamental information on virtual engineering can be found in Bauer and Dangelmaier, 1 Ovtcharova, 2 and in Stark et al 3 Karlberg et al 4 extensively researched the literature to point out the latest developments in simulation-driven development. Weber 5 describes the automotive product development process (PDP) as a complete entity, in which virtual development remains limited to the geometric modeling of components without making use of advanced simulation capabilities.…”

This article presents the new system of virtual powertrain development introduced at Porsche AG that incorporates all phases of the development process, as well as all components and simulation disciplines. The system enables a powertrain in its entirety to be designed and tested virtually. Most activities can be planned and budgeted at the beginning of the project, and interactions that occur are systematically taken into consideration. The hardware-driven development process used until now is completely transmitted to the digital world. Powertrain development is divided into thirteen digital powertrain systems (DPSs), which contain different components and disciplines and are developed throughout the entire product development process. For each DPS, tasks, links, time schedules, reporting scopes, and responsibilities are precisely defined. Finally, a digital vehicle prototype is built from several DPSs. The results are aggregated in several stages, ensuring that core statements are consistently incorporated at all assessment levels, from the individual component to the overall vehicle. Furthermore, this article discusses in detail DPSs that are especially important for battery electric vehicles. For most of the examples, the powertrain of the Porsche Taycan is used. The Driving Performance and Load Spectra DPS provide the necessary design parameters for a new drive system. In the Electric Motor DPS, active parts of the electric motor are designed and all structural components are verified. In the Transmission DPS, all gear set parts are designed and verified. In the Cooling, Lubrication and Actuation DPS, all temperatures are calculated and the lubrication circuit is designed. The Powertrain Dynamics DPS provides information on powertrain vibrations. The article closes with a look at future development trends. The aim is not just to design and verify components but also to completely virtualize function and software development. Therefore, this article presents a system for creating and using a virtual development environment and tracking the results.

“…Karlberg et al [25] did a comprehensive literature review of the state of the art in simulation-driven design in 2013, followed by Motte et al's [26] computer-based design analysis literature review in 2014, which was again followed by an industrial survey of computer-based design analysis from Petersson et al [27]. Sandberg et al [28] stated: "Investigation and evaluations show that supporting tools and relevant information must be made readily available, intuitive, integrated into the environment where they are needed and, ultimately, be perceived as a natural part of daily development for them to be accepted and used."…”

T his paper describes the simulation-driven design process used in engines technology. The research question is "how to use research in the structural analysis and dynamics field to ensure world-class product development?" This paper describes research on simulation methodologies from the design process perspective, demonstrating the need for research in various steps of product development. Each section of the paper includes one or two practical examples in which research was needed to increase product design quality. In the product definition section, the Digital Design Platform (DDP) shows the coupling between product requirements and simulation tasks. At the concept design stage, it is shown that computational methods can optimize the placement of material in the case of the main bearing cap topology. The second example is JuliaFEM, an open-source finite element method (FEM) platform, which is suitable for heavy-duty method development, where the internals of the FE solver is needed to make new calculation methodologies available. The next section is about detailed design, where an example of an oil sump welds fatigue illustrates the continuous improvement of the simulation methodology. The second example is connecting rod fretting calculation, which illustrates the full complexity of the structural analysis and dynamics simulations. The second last process step is the virtual validation, where first the cylinder head simulation methodology shows the internal connections between different disciplines' simulations. Another example here is the crankshaft virtual validation process, which describes the complexity of the "simple" component calculation as well as illustrates the number of needed competencies. Finally, in the validation process step, Big Data analyses describe the internals and complexity of the methodologies. Lastly, counterweight measurement device development illustrates that validation of the simulation models and methods sometimes leads toward a measurement device development project. As a conclusion, all the previous methodologies are used to build the Wärtsilä 31 engine, which is the most efficient four-stroke engine in the world. It is, of course, a performance achievement, but a lot of research in simulation methodologies, as explained, was needed to make a reliable product with such a high cylinder peak pressure.
