Semi-active dampers were conceived in early 1970s as controllable devices with time-variable dissipative properties. Since then these devices were closely studied, developed and applied.
Electro-hydraulic and magneto-rheological semi-active dampers received major attention in the research group. Electro-hydraulic dampers were investigated in the context of load and vibration control in helicopter rotors in collaboration with AgustaWestland.
Magneto-rheological dampers were studied as means of novel quasi-active approach to vibration isolation problems. Our work covered a wide range of related problems including modelling, identification, tests, design and sub-structuring. In that work, particular attention was paid to the use of physics-based methods and appreciation of nonlinear effects.
Current research focus is aimed at:
- refined low order characterization of flow mechanics;
- development of new test and identification techniques;
- novel damper topologies; and
- evaluation of performance benefits in present and future damper applications.
