報告內容摘要：

Nonlinear phenomena are ubiquitous in all engineering systems and in most cases regarded as negative factors to system integration and performance improvement. However, the research development on nonlinear dynamics nowadays continuously reveals that nonlinear phenomena can bring many amazing and advantageous effects in very practical engineering problems such as vibration control, energy harvesting, structure health monitoring, micro/nano-electro-mechanical systems, and so on. Nonlinearity can be employed in various vibration control, energy harvesting and structure health monitoring for achieving advantageous performance. This talk will focus on a brief introduction of a theory for nonlinear analysis and design in the frequency domain with several new concepts such as nonlinear characteristic output spectrum (nCOS) or nonlinear output frequency response function (NOFRF). This method can present a novel and powerful insight into understanding nonlinear dynamics, developed in recent years. Following this, this talk will then focus on a brief introduction to a series of recent advance in exploring nonlinear benefits in engineering: Theory, methods and applications. Some R&D activities will be introduced about a class of bio-inspired anti-vibration structures and their applications in passive vibration control, energy harvesting systems, fault detection and diagnosis and robotics etc, recently investigated in HK PolyU.
