Mechanical Processes With Repeated Attenuated Impacts

Mapping out a “family constellation,” explains Dr. Joy Manné, encompasses exploring previous powerful life events from accidents to adoptions and accessing the deepest dynamics in that family system. This process helps us recognize and then resolve deeply seated family patterns. For example, in order to understand a person’s inability to trust, the family history of betrayal must be uncovered and released. These insights replace resentment with respect, pain with understanding.Dr. Manné uses the knowledge gained from her own practice as well as her educational experiences with Bert Hellinger, the founder of Family Constellations therapy, to clearly describe this technique. Most family constellation sessions are carried out in a group setting, with the facilitator first seeking clarity regarding the issue or problem the client has come to work out. Representatives are then chosen from among the group and the constellation is set up and worked in until it comes to resolution. This may be followed by a closing ritual and advice about how to integrate what the constellation has revealed. Through the use of real-life examples of family constellations, Dr. Manné makes this increasingly popular practice understandable and relatable.

Scientific Editor & Translator E B Kremer (St. Petersburg Mining Institute) This book is devoted to considering in the general case — using typical concrete examples — the motion of machines and mechanisms of impact and vibro-impact action accompanied by a peculiar phenomenon called “impact collapse”. This phenomenon is that after the initial collision, a sequence of repeated gradually quickening collisions of decreasing-to-zero intensity occurs, with the final establishment of protracted contact between the interacting bodies. The initiation conditions of the impact collapse are determined and calculation techniques for the quantitative characteristics of the corresponding motions are proposed. It is shown that impact collapse occurs frequently in reality. The book is intended for experts in applied mathematics, mechanics and mechanical engineering. The resulting formulas and plots are directly usable in engineering practice.

The IPME RAS is one of the leading research institutes of the Russian Academy of Sciences and consists of 18 research units (laboratories). The chapters cover the main research directions of the institute, including nano-,micro-, meso- and macro- mechanics and materials, with ,special emphasis on the problems of strength of materials and service life of structures.

Vibrational mechanics is a new, intensively developing section of nonlinear dynamics and of the theory of nonlinear oscillations. It presents a general approach to the study of the effects of vibration on nonlinear systems. This approach is characterized by simplicity of application and by physical clearness. In recent years a number of new, essential results have been obtained both on the development of the mathematical apparatus of vibrational mechanics and on the solution of certain applied problems. This book reflects those results through the ingenious presentation of the authors OCo well-known scientists from Germany, Denmark and Russia. For the convenience of readers, the main content is preceded by a brief description of the main theses of vibrational mechanics. Contents: The Basis of Vibrational Mechanics; Pendulum and Pendulum Systems under High-Frequency Excitation OCo Non-Trivial Effects; Problems of the Theory of Selfsynchronization; Problems of Creating Dynamic Materials; Vibrational Hydrodynamics and Hydraulics; Some Mathematical Supplements and Generalizations. Readership: Researchers in theoretical and applied mechanics, nonlinear dynamics and nonlinear oscillation theory, as well as mathematicians."

The EUROMECH Colloquium "Dynamics of Vibro-Impact Systems" was held at th th Loughborough University on September 15 _18 , 1998. This was the flrst international meeting on this subject continuing the traditions of the series of Russian meetings held regularly since 1963. Mechanical systems with multiple impact interactions have wide applications in engineering as the most intensive sources of mechanical influence on materials, structures and processes. Vibro-impact systems are used widely in machine dynamics, vibration engineering, and structural mechanics. Analysis of vibro-impact systems involves the investigation of mathematical models with discontinuities and reveals their behaviour as strongly non-linear. Such systems exhibit complex resonances, synchronisation and pulling, bifurcations and chaos, exCitation of space coherent structures, shock waves, and solitons. The aim of the Colloquium was to facilitate the exchange of up-to-date information on the analysis and synthesis of vibro-impact systems as well as on the new developments in excitation, control and applications of vibro-impact processes.

This monograph addresses the systematic representation of the methods of analysis developed by the authors as applied to such systems. Particular features of dynamic processes in such systems are studied. Special attention is given to an analysis of different resonant phenomena taking unusual and diverse forms.

Basic models and concepts of machine dynamics and motion control are presented in the order of the principal steps of machine design. The machine is treated as a coupled dynamical system, including drive, mechanisms and controller, to reveal its behavior at different regimes through the interaction of its units under dynamic and processing loads. The main dynamic effects in machines are explained. The influence of component compliances on accuracy, stability and efficiency of the machines is analyzed. Methods for decreasing internal and external vibration activity of machines are described. The dynamic features of digital control are considered. Special attention is given to machines with intense dynamic behavior: resonant and hand-held percussion ones. Targeted to engineers as well as to lecturers and advanced students.
