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.
