Roughnesses on these ablating surfaces can induce laminar-turbulent transition, which again increases the heat load on the surface. This self-energizing effect can lead to a catastrophic failure of the spacecraft. The role of chemical modelling in high-temperature boundary layers in equilibrium and non-equilibrium is the main focus of the numerical work.

New stationary phases are essential in bioseparation sciences; classical phases are already well developed and reach their limits. The Bioseparation Engineering Group is specialized in synthesis and functionalization of magnetic particles and conductive materials as well as their process implementation. Making use of magnetism or conductivity allows for an additional degree of freedom for state-of- the-art process development.

The main role of the institute within this project was the development of the battery management system. The modular construction with its multistage security system is in charge of monitoring relevant parameters, such as temperature, voltage, current and system state of charge. Furthermore, the BMS communicates with other components, such as the energy management system and the rack safety system.

Takagi-Sugeno Models and Controller Design

Most robotic systems exhibit unneglect- able nonlinearities in their system dynamics, which are to be considered in the design process of the controller. One approach is to use interpolated linear models, so-called Takagi-Sugeno models, to represent the dynamics of nonlinear systems and to use these models for analysis and control design. Within the collaborative research centre ‘Zyklenman- agement von Innovationsprozessen’ of the German Research Council (DFG), the modeling and analysis of non-technical A ballbot and a wheeled inverted pendulum as dynamical systems is investigated using GZCORNGUQHWPUVCDNGPQPNKPGCTTQDQVU agent-based modeling and Takagi- Sugeno models.

Technology for an Aging Society – Individualized Lift-Assist Devices

Rising from a chair is a fundamental movement in daily life and a prerequisite for independent functional ability. Yet, it remains one of the most demanding biomechanical activities as it requires high levels of neuromuscular coordination, muscle strength and postural control. To help patients rise often requires great physical effort by care-givers and there- fore increases their risk of suffering from musculoskeletal disorders. One of our goals is to improve this situation through individualized lift-assist devices. We use individual sit-to-stand motion data to synthesize the dimensions of the mecha- PKUOVJCVRTQXKFGUWUGTURGEKƄEIWKFCPEG QHVJGUGCV#RPGWOCVKEURTKPIƄVVKPI Design of a modular lift-assist device integrated into a the patient’s weight is integrated.

Function modules collect standardized network data (e.g. sensor data, planning data) to realize novel functionalities such as auto- mated sensor-based control of medical devices over the network. As an example, MiMed implemented various use case scenarios for function modules including ‘Navigated Control’ and ‘Neuro Control’, where either position data or neurological data is used to actively control surgical instruments. In both cases, the intensity of the instrument is gradually decreased whenever the instruments get close to a critical structure such as a nerve tissue.

Dynamic Software Update of Programmable Controllers

Current industrial automation plants are controlled by programmable logic controllers (PLC), soft-PLCs or indus- trial PCs. Although the programming interface remains unchanged, using a software-based PLC or an industrial PC enables the implementation of features that were impossible to realize on a hard- ware-based PLC. One of these features is the dynamic software updating (DSU). Since the lifetime of a production facility can be very long, it is inevitable that its software must be updated at some point. This may include the implementation of new features, an increase in performance, The concept of reprogramming a controller at runtime QTUKORNGDWIƄZGU&GRGPFKPIQPJQY QNFXGTUKQPKPDNWGPGYXGTUKQPKPQTCPIG severe this change is, the update of the facility may not be feasible due to down- QHF[PCOKEUQHVYCTGWRFCVKPIKPVJGƄGNF times caused by the shutdown, update of production automation.

Motivation and Objectives A major concern in modern industrial gas turbines is the occurrence of combustion instabilities. Annular combustors burning under lean conditions are susceptible to self-sustained azimuthal oscillations.

More Safety with Improved Protection Gear

In alpine skiing knee injuries remain the major challenge for improved protection equipment. Systematic analysis of injury situations and human anatomy suggest that mechatronic ski bindings may provide the solution. In order to develop the release algorithms of such mechatronic ski bindings, it is necessary to determine the point of force application (PFA) during the

Knowing the PFA and the values of the external load components, we can combine these with the measured joint kinematics. Both together allow us to perform inverse dynamics to calculate the Location of the point of force application during a set of turns. loadings to the critical knee ligaments.

Research Topics

In addition to the investigations of transmission components, the FZG also focuses on basic and comprehensive research topics of transmissions and machine elements in general.

EHL-Tribological Contact

For gear drives, the ratio of sliding to rolling along the path of contact is vari- able. Basic investigations on rolling and sliding contacts are performed on twin- disc machines, which make it possible to adjust any slide-roll ratios at different rotational speeds.

268 Automation and Information Systems Model-Based Engineering of Variant-rich Interdisciplinary CPPS

Besides improving the operation of Industry 4.0-capable systems, one major area of interest for AIS is the engineering of CPPS. Therein, AIS investigates concepts and methods for model-based systems engineering – both in the (discrete) manu facturing engineering domain and in the (continuous) process engineering domain. A special focus is put on the interdisciplinary character of the design of industrial automation systems as well as on increasing the transparency and Aside from these research projects, one of Three-step approach of the CRC handling the complexity throughout the AIS’ main objectives is to rapidly apply the 768: comprehend – model – shape YQTMƅQYQHCWVQOCVKQPU[UVGOUFGUKIP fundamental results for industrial settings, and operation.

Such sheets are used in various applications including but not limited to GNGEVTKEEQPXGTVGTUCPFƄPGDNCPMKPIQH functional components in the commercial vehicle sector. Materials with a strength up to 2000 MPa can be separated reliably by the institute, thanks to the many years of experience with designing shear cutting tools. However, research via industrial collaborations showed a disproportionate increase in wear of the active tool parts due to an unsuitable choice of tool rigidity Cutting tool (upper and lower parts) or process parameters, which makes it no longer possible to manufacture parts To predict edge crack sensitivity of various meeting the requirements in a reliable metallic materials, the edge-fracture process. tensile test was developed and success- Particularly when processing martensitic- fully validated via standardized edge crack ferritic materials, which are increasingly testing methods.

Cost Management

In the area of cost management, the early phases of the product life cycle, the cost responsibility of designers and the neces- sary cooperation between various internal departments and external corporate points are emphasized. Designers and engineers are supported by the research activities of the department for product development in various areas. Thus, me thods and tools are designed to enable cost estimates during early phases of product development and to make them thorough and reliable.

Measurement, Redistribution and Relaxations of Residual Stress

The redistribution of residual stress may result either from the removal of portions of a workpiece during machining or from stress relaxation in the material due to diffusion processes. Residual stress redistribution plays a central role for most experimental techniques applied for resid- ual stress analysis: On the component level residual stress redistribution may lead to undesired distortions of the whole compo- PGPVFWTKPIOCEJKPKPIVQKVUƄPCNUJCRGQT during its operating life.

This includes the

Materials Science and Mechanics of Materials 315 lattice, usually referred to as the reference value. This value depends on the chemical composition of the respective phase, on the microstructural state (existing constit- uents, phase fractions, texture, etc.) as well as on elastic microstrains as a result of local stresses of the crystal lattice on grain level. These local stresses can be ENCUUKƄGFKPVQKPVGTRJCUGOKETQUVTGUUGU resulting from the different micromechani- cal behavior of the individual phases, and intergranular microstresses originating from the elastic and plastic anisotropy of differently oriented grains of one phase.
