Written by Parviz Nikravesh, one of the world’s best known experts in multibody dynamics, Planar Multibody Dynamics: Formulation, Programming, and Applications enhances the quality and ease of design education with extensive use of the latest computerized design tools combined with coverage of classical design and dynamics of machinery principles. Using language that is clear, concise, and to the point, the textbook introduces fundamental theories, computational methods, and program development for analyzing simple to complex planar mechanical systems. The author chose MATLAB® as the programming language, and since students may not be skilled programmers, the examples and exercises provide a tutorial for learning MATLAB. The examples begin with basic commands before introducing students to more advanced programming techniques. The routines developed in each chapter eventually come together to form complete programs for different types of analysis. Pedagogical highlights Contains homework problems at the end of each chapter, some requiring standard pencil-and-paper solution in order to understand the concept and others requiring either programming or the use of existing programs. Electronic highlights All the programs that are listed in the book, and some additional programs, will be available for download and will be updated periodically by the author. Additional materials for instructors, such as a solutions manual and other teaching aids, will also be available on the website. The author organizes the analytical and computational subjects around practical application examples. He uses several examples repeatedly, in various chapters, providing students with a basis for comparison between different formulations. The final chapter describes more extensive modeling and simulation projects. Designed specifically for undergraduates, the book is suitable as a primary text for a course on mechanisms or a supplementary text for a course on dynamics.

This book analyzes several compliant contact force models within the context of multibody dynamics, while also revisiting the main issues associated with fundamental contact mechanics. In particular, it presents various contact force models, from linear to nonlinear, from purely elastic to dissipative, and describes their parameters. Addressing the different numerical methods and algorithms for contact problems in multibody systems, the book describes the gross motion of multibody systems by using a two-dimensional formulation based on the absolute coordinates and employs different contact models to represent contact-impact events. Results for selected planar multibody mechanical systems are presented and utilized to discuss the main assumptions and procedures adopted throughout this work. The material provided here indicates that the prediction of the dynamic behavior of mechanical systems involving contact-impact strongly depends on the choice of contact force model. In short, the book provides a comprehensive resource for the multibody dynamics community and beyond on modeling contact forces and the dynamics of mechanical systems undergoing contact-impact events.

Mehrkörpersysteme sind spezielle mechanische Systeme von Körpern. Diese Körper sind durch Gelenke gekoppelt und bewegen sich unter dem Einfluss von Kräften im Raum. Das Buch führt Leser von den Grundlagen der Technischen Mechanik zu Beschreibungen von Systemen starrer Körper, die eine rechnergestützte Aufstellung erlauben. Im Zentrum der Darstellung stehen die Formen der Bindungen, die die Bewegung der Teilkörper beschränken. Neben offenen Mehrkörpersystemen mit Baumstruktur werden insbesondere geschlossene Mehrkörpersysteme ausführlich behandelt.

This book will be particularly useful to those interested in multibody simulation (MBS) and the formulation for the dynamics of spatial multibody systems. The main types of coordinates that can be used in the formulation of the equations of motion of constrained multibody systems are described. The multibody system, made of interconnected bodies that undergo large displacements and rotations, is fully defined. Readers will discover how Cartesian coordinates and Euler parameters are utilized and are the supporting structure for all methodologies and dynamic analysis, developed within the multibody systems methodologies. The work also covers the constraint equations associated with the basic kinematic joints, as well as those related to the constraints between two vectors. The formulation of multibody systems adopted here uses the generalized coordinates and the Newton-Euler approach to derive the equations of motion. This formulation results in the establishment of a mixed set of differential and algebraic equations, which are solved in order to predict the dynamic behavior of multibody systems. This approach is very straightforward in terms of assembling the equations of motion and providing all joint reaction forces. The demonstrative examples and discussions of applications are particularly valuable aspects of this book, which builds the reader’s understanding of fundamental concepts.

Die Anwendung der Finite-Element-Methode auf nichtlineare technische Probleme hat in den letzten Jahren - auch wegen der stark angestiegenen Rechnerleistung - erheblich zugenommen. Bei nichtlinearen numerischen Simulationen sind verschiedene Aspekte zu berücksichtigen, die das Wissen und Verstehen der theoretischen Grundlagen, der zugehörigen Elementformulierungen sowie der Algorithmen zur Lösung der nichtlinearen Gleichungen voraussetzen. Hierzu soll dieses Buch beitragen, wobei die Bandbreite nichtlinearer Finite-Element-Analysen im Bereich der Festkörpermechanik abgedeckt wird. Das Buch wendet sich an Studierende des Ingenieurwesens im Hauptstudium, an Doktoranden aber auch an praktisch tätige Ingenieure, die Hintergrundwissen im Bereich der Finite-Element-Methode erlangen möchten.

Mit der Renaissance des Schienenverkehrs hat das Spezialgebiet "Schienenfahrzeugdynamik" an Bedeutung gewonnen. Auf entsprechendes Interesse wird das erste Buch im deutschsprachigen Raum stoßen, das hier seinen Schwerpunkt hat. Obwohl es auf der Vorlesung "Schienenfahrzeugdynamik" an der TU Berlin basiert und Vorkenntnisse bezüglich Mechanik, Schwingungslehre und angewandter Mathematik voraussetzt, spricht es auch den Praktiker an. Das Buch behandelt die Vertikaldynamik bis hin zu Komfortbetrachtungen und die Lateraldynamik so weit, daß dem Leser ein Verständnis der Stabilität von Schienenfahrzeugen möglich ist. Den Vorgängen im Kontakt Rad/Schiene wird besondere Aufmerksamkeit gewidmet. Es enthält die jüngsten Erkenntnisse aus Forschung und Bahnpraxis. Die Autoren gehen detailliert auf die spezielle Terminologie der Schienenfahrzeugdynamik und benachbarter Fachgebiete ein.
