C1 - Smart Dampers for Vibration Isolation
Vibration
in today's high-rise buildings, high-speed vehicles and machines severely
affects their safety, comfort and precision. In recent years, it has been
found that magneto-rheological (MR) fluid can be quite promising for
vibration isolation by virtue of its adaptive properties. This controllable
change of state with some desirable features such as high strength and fast
response time show great potential in many applications. In this project, we
aim to design innovative dampers with MR fluids through coupling the
material characteristics with the system dynamics. We also develop
semi-active controllers for the systems with MR dampers. The devices
developed will facilitate the full realization of smart dampers for
vibration control of various systems such as train suspension systems and
civil infrastructures.
Applications
- Suspension systems
- Vibratory machines
- High-rise buildings
- Bridges
Features
- Micron sized, polarizable particles in oil
- Newtonian in absence of applied field
- Develop high yield strength when magnetic field applied
- Provide means for a quiet, fast response interface between electronic
control and mechanical devices
