This updated and enriched new edition maintains its complementarity principle in which the subgroup of rotations, harmonic oscillators, and the conventional complex analysis generate linear and weakly nonlinear approaches, whereas translations and reflections, impact oscillators, and hyperbolic Clifford’s algebras, give rise to the essentially nonlinear “quasi-impact” methodology based on the idea of non-smooth temporal substitutions. In the years since “Nonlinear Dynamics: Between Linear and Impact Limits,” the previous edition of this book, was published, due to a widening area of applications, a deeper insight into the matter has emerged leading to the rudimentary algebraic view on the very existence of the complementary smooth and non-smooth base systems as those associated with two different signs of the algebraic equation j2 =± 1. This edition further includes an overview of applications found in the literature after the publication of first edition, and new physical examples illustrating both theoretical statements and constructive analytical tools. Presents an improved picture of non-smooth temporal transformations using impact systems as a basis for various analyses; Includes new examples of recent applications for problems in energy absorption/harvesting and resonance interactions; Describes a complementarity principle with a range of applications from smooth to discontinuous oscillatory processes.

A specific cost-efficient type of plain journal bearing is the porous journal bearing, which possesses a pervious bush that serves as a lubricant reservoir. The current work is concerned with modeling porous journal bearings in multibody systems, for which dynamical models are needed to investigate the bearing’s behavior. Such porous journal bearing models as well as models of elementary rotor-bearing systems including these, were developed and investigated during the course for this work.

This book describes the design experience of automatic machines and the theoretical background for controlling them. Unlike the existing literature, it includes design concepts and their relationship with the dynamic behavior of automated devices, and links the dynamic response of the machine elements with the actuators that constitute an automatic machine. As such, it demonstrates that it is vital to properly model any automatic machine as a single system and find the final response to have a good design and control scheme. The introduction describes the background for designing automatic machines, their uniqueness in machine design, and the need to understand dynamic behavior. The following chapters provide the background for modeling multibody systems, examples of typical automatic machines, and the basis for determining the dynamic response of the most common actuators (motor, pneumatic, and hydraulic pistons and valves). The fourth chapter describes the dynamic response of the most common sensors utilized in automatic machines, while the fifth chapter includes the dynamic models of the machine elements that connect the actuators with the end effects (specific tools for each particular application). The final chapters contain examples of dynamic models for different automatic machines, including all the elements that affect the final response, and describe the simulation techniques (and their application to the examples) and the application of the transfer function for estimating the transient response of automatic machines.
