This work considers dampers that do not solely focus on a single strategy but instead combine them. The capabilities of conventional dry friction dampers are expanded by taking into account piecewise defined contact geometries. This leads to friction dampers that change their behavior depending on the amplitude of the oscillations. The vibration damping device in this work, introduces damping at high oscillation amplitudes and takes advantage of absorption at low oscillation amplitudes.

The gas foil bearing (GFB) technology is a key factor for the transition to oil-free rotating machinery. Among numerous advantages, GFBs offer the unique ability to be lubricated with working fluids such as refrigerants. However, the computational analysis of refrigerant-lubricated GFB–rotor systems represents an interdisciplinary problem of enormous complexity. This work pushes forward existing limits of feasibility and establishes a new strategy that enables stability and bifurcation analyses.

The impact of two non-uniform elastic rods is considered and a recursive method was developed that solves the inverse problem: Find the location-dependent impedance function of the impacting rod that generates a prescribed impact force. The developed method delivers exact solutions in closed-form. Moreover, a condition is derived which states if a physically meaningful solution exists. Finally, the underlying 1D model has been validated experimentally.

In dieser Arbeit wird der Reibwert für den trockenen Kontakt zweier gleitender metallischer Körper in Abhängigkeit verschiedener physikalischer Parameter berechnet. Dafür wird ein thermomechanisches Modell entwickelt und für verschiedene Kontaktkonfigurationen unter Berücksichtigung der Oberflächenrauigkeit beider Kontaktkörper ausgewertet. Darüber hinausgehende Untersuchungen zu den Auswirkungen des berechneten Reibwerts im Kontext von reibungserregten Schwingungen schließen sich an. - Within this work, the friction coefficient is calculated for the dry contact of two sliding metallic bodies as a function of various physical parameters. For this purpose, a thermomechanical model is developed and evaluated for different contact configurations considering the surface roughness of both contact bodies. Subsequent investigations on the consequences of the calculated friction coefficient in the context of friction-induced vibrations are carried out.

Für die dynamische Analyse hydraulischer Ventile wird ein Verfahren basierend auf der singulären Störungsrechnung und dem Mittelwertbildungsverfahren entwickelt. Es erfolgt die Berechnung periodischer Lösungen sowie die Analyse der Stabilität unter dem Einfluss nicht-glatter Phänomene. Basierend auf dieser Analyse werden reduzierte Modelle entwickelt, mit denen eine teils signifikante Rechenzeitersparnis in der Simulation instationärer Bewegungen und in der nichtlinearen Regelung erzielt wird. - A method based on the singular perturbation theory and the averaging method is developed for the dynamic analysis of hydraulic valves. Periodic solutions are calculated and stability is analyzed under the influence of non-smooth phenomena. Based on this analysis, reduced models are developed, which exhibit significantly improved computational time efficiency, both in the simulation of non-stationary motions as well as in nonlinear valve control.

Hydraulics Of Open Channel Flow written by Sergio Montes and has been published by American Society of Civil Engineers this book supported file pdf, txt, epub, kindle and other format this book has been release on 1998 with Technology & Engineering categories.

This book emphasizes the dynamics of the open channel flow by attempting to provide a complete framework of the basic equation of fluid motion which is used as a building block for the treatment of many practical problems. It provides up-to-date coverage of modern techniques while providing a more rigorous analytical foundation for those who require it. The structure follows a logical progression from a description and classification of open channel flows, through a development of the basic equations of motion for steady and unsteady flow, to an analysis of varied cases of flow.
