Design Evolution of a Diesel Engine Piston
International Journal of Research, 2019Co-Authors: Pedireddla Srinu, V.tirupathi RaoAbstract:A piston is a major component of to and fro motion engines. It transfers the power form expanding gases in the cylinder to the crank shaft through the con rod. Now a three dimensional solid model of piston along with different dimensions is Designed with the help of AutoCAD software. By applying the same pressures and temperatures for different Piston head diameter with the help of AutoCAD and Ansys 16.0 Software, we can get the evaluated results of von-misses stresses, thermal flux, and thermal gradient and directional deformations for that piston Design. General materials for the piston is Structural steel, cast steel, forged steel, Aluminum alloys, and Nickel alloys. In our project Cast Aluminum alloy is used as piston material. It is an excellent material in thermal conductivity and also light in weight. The stress analysis results also help us to improve component Design and also have given us the knowledge on the deformation and thermal handling sections on the piston.

Unifying Runtime Adaptation and Design Evolution
2009Co-Authors: Brice Morin, Thomas Ledoux, Mahmoud Ben Hassine, Franck Chauvel, Olivier Barais, Jean-marc JézéquelAbstract:The increasing need for continuously available software systems has raised two key-issues: self-adaptation and Design Evolution. The former one requires software systems to monitor their execution platform and automatically adapt their configuration and/or architecture to adjust their quality of service (optimization, fault-handling). The later one requires new Design decisions to be reflected on the fly on the running system to ensure the needed high availability (new requirements, corrective and preventive maintenance). However, Design Evolution and selfadaptation are not independent and reflecting a Design Evolution on a running self-adaptative system is not always safe. We propose to unify run-time adaptation and run-time Evolution by monitoring both the run-time platform and the Design models. Thus, it becomes possible to correlate those heterogeneous events and to use pattern matching on events to elaborate a pertinent decision for run-time adaptation. A flood prediction system deployed along the Ribble river (Yorkshire, England) is used to illustrate how to unify Design Evolution and run-time adaptation and to safely perform runtime Evolution on adaptive systems.

Design Evolution through customer interaction with functional prototypes
Journal of Engineering Design, 2007Co-Authors: R.i. Campbell, G J Booysen, Ludrick Barnard, M Truscott, Rebecca Cain, M.j. Burton, D.j. De Beer, Richard J.m. HagueAbstract:There can be a tendency, even within companies who practice concurrent engineering, to limit customer involvement to the initial and final stages of the new product development process only. This invites the possibility that the customers' opinions will be lost or at least diluted during the intermediate stages of the process. A joint research project involving Loughborough University and the Central University of Technology, Free State has provided evidence, through several case studies, that physical models created via rapid prototyping enable the customer to be involved throughout the development process. The benefits associated with using physical models are discussed, showing that these models have a unique role to play in promoting customer involvement. The authors propose the method termed Customer Interaction with Functional Prototypes, which has been implemented during several new product development projects carried out in both academic and industrial environments. At present, the Customer Inter...

Rapid tooling strategies for product customisation and Design Evolution
Journal for new generation sciences, 2007Co-Authors: R.i. Campbell, D.j. De Beer, G J BooysenAbstract:Rapid Tooling (RT) has been widely used to produce functional prototypes in the end-use material and sometimes to serve as temporary production tooling in order to achieve an earlier product launch date. Previous research on RT Design considerations has concentrated upon Design of the tools themselves, e.g. the use if conformal cooling passages around the cavity. Little has been published on the more strategic issue of how and when RT should be used to promote various product development strategies. With product life cycles shortening and ""mass customisation"" becoming more prevalent, it is likely that RT will become the tooling of choice for a wider range of products, even those currently considered mass production items. This scenario presents a number of issues to the Designer. Does the product Design need to change to match the capabilities of RT? Can more use be made of modular tooling to keep costs down? Which sorts of Design Evolutions are best suited to this route? This paper seeks to address these questions by reviewing the knowledge gained about RT from previous case studies and by devising a number of tooling strategies that companies should consider. It concludes by identifying the research questions that must be answered in order for these strategies to be fully realised.
