Abstract: Employing nonlinearity in engineering applications is a challenging but very promising topic in the literature in recent years. Nonlinearity can be employed in various vibration control, energy harvesting and structure health monitoring for achieving advantageous performance. A special issue on this topic will be published on the leading journal – Mechanical Systems and Signal Processing. 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, 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.

BioXingjian Jing (M’13, SM’17) received the B.S. degree from Zhejiang University, China, in 1998, the M.S. degree and PhD degree in Robotics from Shenyang Institute of Automation, Chinese Academy of Sciences, in 2001 and 2005 respectively. He achieved the PhD degree in nonlinear systems and signal processing from University of Sheffield, U.K., in 2008. He is now an Associate Professor with the Department of Mechanical Engineering, the Hong Kong Polytechnic University (PolyU). Before joining in PolyU as an Assistant Professor in Nov 2009, he was a Research Fellow with the Institute of Sound and Vibration Research, University of Southampton. His current research interests include: nonlinear dynamics, vibration and control. Dr Jing is the recipient of a series of academic and professional awards including 2016 IEEE SMC Andrew P. Sage Best Transactions Paper Award, 2017 TechConnect World Innovation Award in US, 2017 EASD Senior Research Prize in Europe and 2017 the First Prize of HK Construction Industry Council Innovation Award. He has published more than 130 referred papers and obtained about 15 patents filed in China and US. He currently serves as Technical Editor of IEEE/ASME Trans. on Mechatronics, and Associate Editor of Mechanical Systems and Signal Processing. He was the lead editor of a special issue on “Exploring nonlinear benefits in engineering” published in Mechanical Systems and Signal Processing 2018.
