This book presents insights from the IUTAM Symposium on Nonlinear Dynamics for Design of Mechanical Systems Across Different Length/Time Scales. It covers a diverse array of topics, including applications of parametric amplification and self-excitation, as well as the design and analysis of devices and systems that harness geometric and material nonlinearities. The book features chapters on nonlinear energy transfer, eigenfrequency detection through subharmonic and superharmonic resonances, and the innovative use of nonlinear mode localization. The authors explore dynamic stabilization under high-frequency excitation, the utilization of multimode interactions and nonlinear normal modes, and the application of nonlinear resonance and bifurcation in creating ultrasensitive sensors and high-performance actuators. This book provides a comprehensive record of the symposium''s discussions, representing a collective effort to expand our understanding of nonlinear phenomena and its potential to reshape the landscape of mechanical system design.

"Nonlinear Oscillations in Mechanical Engineering" explores the effects of nonlinearities encountered in applications in that field. Since the nonlinearities are caused, first of all, by contacts between different mechanical parts, the main part of this book is devoted to oscillations in mechanical systems with discontinuities caused by dry friction and collisions. Another important source of nonlinearity which is covered is that caused by rotating unbalanced parts common in various machines as well as variable inertias occurring in all kinds of crank mechanisms. This book is written for advanced undergraduate and postgraduate students, but it may be also helpful and interesting for both theoreticians and practitioners working in the area of mechanical engineering at universities, in research labs or institutes and especially in the R and D departments within industrial firms.

Die Autoren gehen u.a. auf folgende Themen ein: Eigenfrequenzen und Eigenbewegungen regulärer Strukturen und deren Beeinflussung, Stabilitätsbedingungen, erzwungene Torsionsschwingungen in Fahrzeugantrieben, Schwingungen beim Anfahren und Bremsen von Maschinenantrieben, Resonanzdurchlauf von Rotoren, parameter- und selbsterregte Schwingungen (z.B. in Schneckengetrieben), optimale Positionierbewegungen, Maßnahmen zum Massen- und Leistungsausgleich, zur Schwingungsverminderung und Bedingungen für die Selbstsynchronisation von Unwucht-Erregern.

Für die 3. Auflage wurde das Buch aktualisiert und wesentlich erweitert um Abschnitte zu Torsionsschwingungen im KFZ-Antriebsstrang, zu Vibrationsförderern und zu nichtlinearen, insbesondere reibungserregten Schwingungen.
