Dr Li’s research focuses on the optimum multidomain vibration-absorber synthesis methodology.

There are numerous design possibilities for vibration absorbers involving components from multiple domains (mechanical, hydraulic, pneumatic and electrical). The conventional design approach for a multidomain absorber only covers a limited number of specific designs while leaving a large variety of design potential unexplored. Dr Li is developing a systematic methodology to synthesize the optimum vibration-absorber properties (consisting of damping, stiffness and inertance), using multidomain components. Dr Li’s work makes use of analytical-modelling, numerical-simulation and experimental-verification techniques. The developed methodology can be applied for a wide range of applications, specifically including the designs of hydro-pneumatic and mechatronic suspensions for automotive and trailing arm bushes for railway vehicles.
