  abstract     = {{<jats:p>Many industries have significant requirements regarding temperature control, air humidity and air pollution which must be strictly adhered to avoid bacterial formation and contamination. High refrigeration specifications are only required in certain areas. However, these specifications are often applied across the whole production hall which results in unnecessarily high energy demand and usage. A more energy efficient approach is the localized cooling of the product, which conditions the direct environment of the product only. This leads to the consideration of separating or localizing the products specifically requiring refrigeration in the production hall. In this paper, localized product cooling systems are analyzed in order to identify the savings potential associated with a localized refrigeration system. The study shows the energy savings potential for a manufacturing company located in three different locations: in Germany, Canada and the USA.</jats:p>}},

  abstract     = {{Cooperative cyber-physical systems (CCPS) are driven by the tight coordination between computational components, physical sensors and actuators, and the interaction with each other over system bounds. The software development of CCPS is getting more complex because of the tight integration, heterogeneous technologies, as well as safety and timing requirements. Therefore, new engineering approaches, such as model-driven development methods, are required, along with communication architectures with self-* capabilities. Both will support the developer in specifying such a system effectively and efficiently. However, the application of such techniques to the development of CCPS has not been addressed sufficiently so far. This paper presents an experience report of developing a cooperative delta-robot system that juggles a ball without a central control or camera system. For the development, an intelligent network architecture and model-driven development method for CCPS are applied.

  abstract     = {{Radial shaft seals are used in a variety of applications, where rotating shafts in steady housings have to be sealed. Typical examples are crankshafts, camshafts, differential gear or hydraulic pumps. In the operating state the elastomeric seal ring and the shaft are separated by a lubrication film of just a few micrometers. Due to shear strain and fluid friction the contact area is subject to a higher temperature than the rest of the seal ring. The stiffness of the elastomeric material is intensely influenced by this temperature and thus contact pressure, friction and wear also strongly depend on the contact temperature. In order to simulate the contact behavior of elastomer seal rings it is essential to use a comprehensive approach which takes into consideration the interaction of temperature, friction and wear. Based on this idea a macroscopic simulation model has been developed at the MEGT. It combines a finite element approach for the simulation of contact pressure at different wear states, a semi-analytical approach for the calculation of contact temperature and an empirical approach for the calculation of friction. In this paper the model setup is presented, as well as simulation and experimental results.}},

In order to establish a common understanding as basis for the holistic robustness consideration within the Collaborative Transregional Research Centre 30 (CRC Transregio 30), a joint development of methods for analysing and optimising the robustness is necessary. The term "robustness", however, has been used differently in the various disciplines of the CRC Transregio 30. Thus, this contribution proposes a common definition of robustness for the whole research centre. In addition, a procedure model for considering the robustness with a collection of methods, that can be combined or adapted by the involved disciplines, is presented. The validation of the recommended procedure model has been conducted by a compression moulding process.}},

  abstract     = {{Functional gradation denotes the systematic and reproducible microstructure adjustment of a single material component for the customisation of the macroscopic properties (e.g. hardness or ductility). This customisation is tailored with respect to the later intended application of the component. The improved material utilisation enables light weight design and simplifies the recycling by using single material components. Hence, it provides a resource-conserving alternative for modern composite materials and offers an innovative approach for customisable smart products of the future. Manufacturing functionally graded components requires complex thermo-mechanically coupled process chains that increase the effort for the holistic design. To realise the full potential offered by functional gradation, the available planning and optimisation methods as well as the surrogate models developed during the first research period of the Collaborative Transregional Research Centre (CRC Transregio 30) are significantly enhanced. Furthermore, all the methods and surrogate models as well as the process knowledge obtained by laboratory experiments are consolidated in a comprehensive computer-aided framework to provide a continuous support for the engineer during the planning process. This contribution proposes the methodical foundations within the framework along the planning process: Component description, synthesis of suitable manufacturing process chains, and optimisation of the process chain parameters as well as the specification of the production system. The methods are validated based on an exemplary planning task within the CRC Transregio 30.

The resulting procedure model allows the specification of the desired property distribution, the subsequent identification of process chains capable of producing the component as well as the optimisation of each process parameter.

The basis for this decision-support is provided by a framework for the computer-aided planning and optimisation of manufacturing process chains of functionally graded components, which is still under development. To distinguish between several alternative process chains it is necessary to consider those decision criteria that can not explicitly be specified within the CAD model. A matrix-supported algorithm guarantees a consistent weighting of these decision criteria while enabling a fine-granular rating scale. As a result, a ranking of the different process chains is achieved that constitutes the basis for the decision maker to select the favourite alternative.
