On December 4 and 5, 2018, the affiliate portal Konstruktionspraxis will host the 3rd "Anwendertreff Leichtbau" in Würzburg, Germany, that focusses on new topics from lightweight design.
At this year's "Anwendertreff Leichtbau", seven lectures will provide an overview of lightweight design applied in concepts, structural design, materials and production. The conference will also present the current state in science and technology on the topics of composite materials, additive production and joining in lightweight design. In six practical forums and one workshop, the respective lightweight design strategies will be taken up again and selected examples will show how the designer and developer can implement them in his daily work.
According to VDI 6220, bionics combines biology and technology in interdisciplinary cooperation with the aim of solving technical problems through abstraction, transfer and application of knowledge gained from biological models. Prof. Dr. Heike Beismann from the Westfälische Hochschule will explain how bionics can be integrated into development processes. In her lecture, she presents the work stages in which the use of bionics is particularly promising, and she will show what should be taken into account during the implementation of bionics.
Methodical Selection of Materials
In addition to structural lightweight design, further potential can be tapped through lightweight material design. "Especially in substructures with a clearly dominant stress state, optimum material selection enables weight reductions. This material selection requires a methodical procedure with efficient integration into the development process in order to determine the best option for a substructure from the constantly growing range of materials," says Marian Kozlowski of RWTH Aachen University. In his lecture he will present a methodical material selection process ranging from the results of a topology optimization to the definition of the material.
Designing fiber composite structures
Fiber-reinforced composites are particularly well suited for lightweight design and are increasingly being used in mechanical engineering as well as in aviation and vehicle construction. "Thanks to the wide range of design options, the components can be optimized for specific applications," explains Jürgen Filsinger of the Fraunhofer IGCV. "The unlimited degree of freedom extends all the way to component manufacturing, where the ideal process chain has to be developed depending on the materials selected, the construction method and component design, as well as the throughput times and planned batch sizes. In his lecture, Filsinger will discuss the interaction of component complexity and material throughput using exemplary manufacturing technologies for various fiber composite material systems and provide an insight into the diversity of manufacturing methods.
Searching for suitable connections
Since hybrid structures are created by a methodical selection of materials, the joining technologies must be adapted to materials of the same type. Dr.-Ing. Jens Standfuß from Fraunhofer IWS will present the joining possibilities of fiber composite/metal and metal/metal composite construction methods. In his lecture, possible applications in different areas of mechanical and plant engineering as well as automotive and aerospace will be shown and aspects of design such as strength, corrosion and conductivity in connection with joining technology will be addressed.
Additive manufacturing of components
Additive manufacturing (AM) is one way of manufacturing components that are optimized in terms of topology and shape. According to Prof. Dr.-Ing. Franz-Josef Villmer of the HS Ostwestfalen-Lippe, the improvement of AM machines and processes is increasingly offering the possibility of direct production of end user parts. "However, the potential of AM can only be fully exploited if the design is geared to increasing the design freedom provided by AM and the designers are familiar with the possibilities and limitations," says Villmer. In his lecture, he will present the current strengths and weaknesses of additive manufacturing of metal and plastic parts and highlight the opportunities of lightweight design.
