Abstract

This book entitled Development and Application of Nonlinear Dissipative Device in Structural Vibration Control contains contributions that focus on the development and application of innovative nonlinear dissipative systems that mitigate the potentially catastrophic effects of extreme loading by incorporating new materials or effective mechanical control technologies. Moreover, new nonlinear analytical methods for distinctive vibrating structures under different excitations are also highlighted in this book. It is notable that nonlinear dampers prove superior in energy dissipation compared to linear dampers, such as the wide frequency band of vibration attenuation and high robustness. In light of this, nonlinear dampers have been utilized in many different cases. For example, pounding-tuned mass dampers are employed to alleviate the excessive vibration of power transmission towers, and self-powered magnetorheological dampers are used to suppress the undesirable vibration of long stay cables. The content of this book covers a wide variety of topics that can be mainly divided into three categories, namely, new nonlinear dissipative devices, new simulation tools for vibrating structures undergoing nonlinear stage, and new design/optimum methods for dissipative devices and isolation systems. The contributions presented in this book can provide valuable and constructive reference material for the further study of nonlinear dampers and structures.

Abstract

The combination of distinct materials is a key issue in modern industry, whereas the driving concept is to design parts with the right material in the right place. In this framework, a great deal of attention is directed towards dissimilar welding and joining technologies. In the automotive sector, for instance, the concept of “tailored blanks”, introduced in the last decade, has further highlighted the necessity to weld dissimilar materials. As far as the aeronautic field is concerned, most structures are built combining very different materials and alloys, in order to match lightweight and structural performance requirements. In this framework, the application of fusion welding techniques, namely, tungsten inert gas or laser welding, is quite challenging due to the difference in physical properties, in particular the melting point, between adjoining materials. On the other hand, solid-state welding methods, such as the friction stir welding as well as linear friction welding processes, have already proved to be capable of manufacturing sound Al-Cu, Al-Ti, Al-SS, and Al-Mg joints, to cite but a few. Recently, promising results have also been obtained using hybrid methods. Considering the novelty of the topic, many relevant issues are still open, and many research groups are continuously publishing valuable results. The aim of this book is to finalize the latest contributions on this topic.

Abstract

Power electronics technology is still an emerging technology, and it has found its way into many applications, from renewable energy generation (i.e., wind power and solar power) to electrical vehicles (EVs), biomedical devices, and small appliances, such as laptop chargers. In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (photovoltaic (PV) and wind) have been installed, all of which are handled by power electronics technology. The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in ?robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and ?smart control of power electronics in devices, microgrids, and at system levels.
