Often, Monte-Carlo simulations are used to findregions, where the system response is sensitive to parameteruncertainties. These simulations require a large computation time.Therefore, an approximate method to calculate the envelopes of thefrequency response functions is developed in this paper. An example of anonlinear system with cyclic symmetry is a bladed disk assembly withfriction dampers. Friction dampers can be installed underneath the bladeplatforms of turbine blades. Due to dry friction and the relative motionbetween blades and dampers, energy is dissipated, which results in areduction of blade vibration amplitudes. By optimizing the mass of thefriction dampers, the best damping effects are obtained, which lead toan increase in the reliability of the turbine. In this paper, thecalculated response of a mistuned bladed disk assembly with frictiondampers is discussed. An approximate method is developed to calculatethe envelopes of the corresponding frequency response function forstatistically varying eigenfrequencies of the blades. Regions wherelocalization can occur with a high probability, are calculated by thismethod.","lang":"eng"}],"date_created":"2019-04-15T10:14:18Z","keyword":["bladed disk assembly","mistuning","sensitivity","localization"],"type":"journal_article","department":[{"_id":"151"}]},{"page":"1597 - 1609","language":[{"iso":"eng"}],"_id":"8918","user_id":"55222","doi":"10.1016/S0960-0779(99)00080-6","volume":11,"title":"On some regularities in dynamic response of cyclic periodic structures","status":"public","year":"2000","publication_identifier":{"issn":["0960-0779"]},"author":[{"first_name":"Tomasz","last_name":"Krzyzynski","full_name":"Krzyzynski, Tomasz"},{"first_name":"Karl","last_name":"Popp","full_name":"Popp, Karl"},{"last_name":"Sextro","first_name":"Walter","full_name":"Sextro, Walter","id":"21220"}],"date_updated":"2022-01-06T07:04:05Z","intvolume":"        11","date_created":"2019-04-15T09:58:17Z","type":"journal_article","department":[{"_id":"151"}],"publication":"Chaos, Solitons \\& Fractals","issue":"10","citation":{"short":"T.

These elements placed between adjacent blades reduce the vibration amplitudes by means of dry friction resulting from centrifugal forces acting on the elements and relative displacements of the blades. However, the application of these friction elements results in an additional dynamical coupling which together with mistuning of some system parameters (e.g., blade eigenfrequency or contact parameters) may cause localization of vibration. In the present paper a linear approximation of such a system is investigated. The structure composed of cyclic periodic cells modelled each as a clamped-free beam interacting with each other by means of viscoelastic elements of complex stiffness is applied for dynamic system analysis. In case of free vibrations as well as in case of steady-state dynamic response to a harmonic pressure field, a perfect periodic structure and the structures with periodically mistuned parameters (blade eigenfrequencies and contact parameters) are studied. Some regularities in the dynamic response of the systems with mistuning have been noticed. Despite the fact that only a linear approximation has been used, the results and conclusions can be applied for models which describe the blade interaction in a nonlinear way.","lang":"eng"}]},{"date_updated":"2022-01-06T07:04:05Z","status":"public","year":"2000","title":"Optimization of Interblade Friction Damper","author":[{"last_name":"Panning","first_name":"Lars","full_name":"Panning, Lars"},{"first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter","id":"21220"},{"full_name":"Popp, Karl","last_name":"Popp","first_name":"Karl"}],"user_id":"55222","page":"1-8","language":[{"iso":"eng"}],"_id":"8919","abstract":[{"lang":"eng","text":"the vibration amplitudes of bladed disk assemblies can be reduced significantly by means of friction damping devices such as shrouds, damping wires and interblade Friction dampers. in practice, interblade Friction dampers are applied in rotating arrangements with various geometries showing curved or flat surfaces like so-called wedge-shaped dampers. this paper is focusing on a computation method to predict the dynamical behaviour of turbine blades with Friction dampers including both, curved and wedge-shaped dampers with hertzian and non-herutian contact conditions, respectively. the presented computation method uses a 3d contact model to calculate the contact forces, including normal and tangential stiffnesses, roughness and microslip effects. the relative displacements in the contact area can be expressed by means of 6 dof of the blade platforms and 6 rigid body dof of the damper including translational and rotational displacements. the relative displacement of the Friction damper with respect to the adjacent blades can be derived from the contact kinematics of the blade-damper-blade system and the equations of motion of the Friction damper. thus, the model can be applied to investigate spatial motions of the bladed disk assembly including bending and torsional vibrations. a comparison of different Friction damper designs with respect to an optimal damper geometry and damper mass is presented. the advantages and disadvantages of each design will be discussed. experimental results are shown to validate the developed computation method."}],"publication":"International Gas Turbine \\& Aeroengine Congress \\& Exhibition, ASME","citation":{"bibtex":"@inproceedings{Panning_Sextro_Popp_2000, place={Munich, Germany}, title={Optimization of Interblade Friction Damper}, booktitle={International Gas Turbine \\&#38; Aeroengine Congress \\&#38; Exhibition, ASME}, author={Panning, Lars and Sextro, Walter and Popp, Karl}, year={2000}, pages={1–8} }","ama":"Panning L, Sextro W, Popp K.
