Volume 3 – Conference

We are pleased to present the conference proceedings for the 12th edition of the International Fluid Power Conference (IFK). The IFK is one of the world’s most significant scientific conferences on fluid power control technology and systems. It offers a common platform for the presentation and discussion of trends and innovations to manufacturers, users and scientists. The Chair of Fluid-Mechatronic Systems at the TU Dresden is organizing and hosting the IFK for the sixth time. Supporting hosts are the Fluid Power Association of the German Engineering Federation (VDMA), Dresdner Verein zur Förderung der Fluidtechnik e. V. (DVF) and GWT-TUD GmbH. The organization and the conference location alternates every two years between the Chair of Fluid-Mechatronic Systems in Dresden and the Institute for Fluid Power Drives and Systems in Aachen. The symposium on the first day is dedicated to presentations focused on methodology and fundamental research. The two following conference days offer a wide variety of application and technology orientated papers about the latest state of the art in fluid power. It is this combination that makes the IFK a unique and excellent forum for the exchange of academic research and industrial application experience. A simultaneously ongoing exhibition offers the possibility to get product information and to have individual talks with manufacturers. The theme of the 12th IFK is “Fluid Power – Future Technology”, covering topics that enable the development of 5G-ready, cost-efficient and demand-driven structures, as well as individual decentralized drives. Another topic is the real-time data exchange that allows the application of numerous predictive maintenance strategies, which will significantly increase the availability of fluid power systems and their elements and ensure their improved lifetime performance. We create an atmosphere for casual exchange by offering a vast frame and cultural program. This includes a get-together, a conference banquet, laboratory festivities and some physical activities such as jogging in Dresden’s old town.:Group 8: Pneumatics Group 9 | 11: Mobile applications Group 10: Special domains Group 12: Novel system architectures Group 13 | 15: Actuators & sensors Group 14: Safety & reliabilit

Weight estimation of parametrically design of fuel and hydraulic systems of a commercial airplane

This project aims to study the feasibility of a program capable of modelling and obtaining the total weight of the fuel system of commercial aircrafts. Once this program has been created, focus can be turned to the hydraulic system, with the aim of achieving the same. In order to achieve this, all the components of both systems are explained, and how these components work side by side to perform the necessary functions. A study of the current solutions used has been carried out in order to estimate the mass of the systems studied (statistical based formulas). The methodology followed within the project is then explained in order to obtain the code: the common characteristics, patterns, calculations of the necessary elements and explanation of the hypotheses and simplifications considered. Next, how the program works is explained in detail, carried out in Python language, the outputs that are obtained with its execution, and the limitations of the code. It is clear to see there is not enough information, or it is confidential, to make a program for the hydraulic system. After testing the code for the fuel system, analysing the results obtained by the program and comparing them with the values of the current statistical formulas, the study concludes that although the approach of a parametric program is interesting from the point of view of flexibility, we must continue working on and improving the project, as well as collecting real data, to obtain results that point to the real value of the aircraft. It is hoped that this project will also serve the reader as a guide to understand how both systems work and their basic functionalities.Outgoin

The potential role of new technology for enhanced safety and performance of nuclear power plants through improved service maintenance

Refinements in the safety and performance of nuclear power plants must be made to maintain public confidence and ensure competitiveness with other power sources. The aircraft industry, US Navy, and other programs have proven many advanced service maintenance methods that may improve commercial nuclear plants. This thesis is concerned with how new technologies in sensing and monitoring can be used to reduce the potential for hardware failures. The specific components with the greatest impacts upon safety and performance were determined using historical data from the experience of the nuclear industry. Failure modes associated with selected components are used to indicate the most important monitoring needs and these requirements help focus a technology survey for potential improvements. The thesis concludes with a discussion of possible applications which may enhance monitoring needs. Proposals for focusing future research to further develop appropriate technologies are presented. Nuclear facility managers are provided a means to self-analyze the status of onsite efforts to improve vital safety and performance related equipment in this thesis. Many of the monitoring needs and potential improvements indicated have general application to most plants. The process discussed in this report can be used to further tailor technology to plant specific needs
