摘要: The seminar aims to offer an overview of various vibration phenomena present in mechanical systems with diverse natures and characteristics: from nano to large  scale. It delves into the impact of vibration phenomena and also explores experimental techniques. The seminar will show recent scientific studies on the following specific topics: mechanical transmissions,  passive suspensions and isolation systems,  active vibration control, anti-seismic devices,  bio-engineering. A segment of the seminar centers on mechanical transmissions, particularly gear vibrations. It scrutinizes modeling and testing techniques,  alongside diagnostic and prognostic methods. Numerical techniques are discussed and compared with Standards and Codes, which currently serve as the conventional design tools. The seminar also covers methods for mitigating the effects of vibrations,  with a particular focus on new isolation systems that leverage nonlinearities to enhance filtering performance. The talk also addresses the vibration characteristics of meta-structures and metamaterials, providing examples of their applications. A novel technique for alleviating Parkinson's disease and essential tremors is introduced, leveraging mechanical modeling of the human body and its response to electrical stimuli.
