His research focuses on smart materials and their applications, microfluidics, rheology, and intelligent mechatronics. He is serving as editor or editorial board member for several international journals, including IEEE/ASME Transactions on Mechatronics, Smart Materials and Structures, Scientific Reports, RSC Advances, etc. He has published more than 300 journal and conference papers with more than 5200 citations. He is a recipient of Fellow of the Engineers Australia, the Fellow of Institute of Physics (UK), Australian Endeavour Research Fellowship, JSPS Invitation Fellowship, Vice-chancellor's Award for Interdisciplinary Research Excellence, and numerous Best Paper Awards.


Topic: Magnetorheological Materials and Their Innovative Engineering Engineering Applications 

Abstract:Magnetorheological (MR) materials, including MR fluids and MR elastomers,are smart materials that their damping and stiffness can be controlled by an external magnetic field. These materials have attracted considerable interests in recent years because of its potential as a simple, quiet, and rapid-response interface between electronic controls and mechanical systems. This talk will present two current research projects on the application of MR technologies in two research fields: high speed trains and structural protection. The first topic aims to address the instability and ride comfort of current high speed trains when their running speeds are above 300 km/h. Both simulation and preliminary experimental work have demonstrated that MR dampers can improve train’s critical speed and ride comfort. The second topic aims to develop semi-active MR elastomer isolators for structural control. We prototyped innovative multi-layer isolators and evaluated their performance under different external excitations. The long-term objective is to promote MR isolators for real structural control.
