Magneto-Rheological Fluid

Descriptions

  • A magnetic fluid called MR fluid is a smart material that controls properties through magnetic fields. Form a mixture of magnetic particles and various functional additives into the base oil.

  • The MR(electrofluidic)suspension has properties that control viscosity depending on the size of the electric and magnetic fields. So it can reduce vibration coming from the road surface of the vehicle depending on changes in external road conditions.

Application Area

Vehicles, Military, Rail, Artificial Joint, Architecture, Home Appliances

Product information

A magnetic fluid called MR fluid is a smart material that controls properties through magnetic fields. Form a mixture of magnetic particles and various functional additives into the base oil.

MR Fluids consist of magnetic (typically iron) particles in a carrier fluid. In the presence of a magnetic field, the micron-sized particles link and change the fluid to a semi-solid in milliseconds. When the magnetic field is removed, the fluid just as quickly reverts back to its natural free-flowing state. Furthermore, the degree to which the fluid changes to a semi-solid is proportional to the strength of the magnetic field, giving the fluid infinite controllability and precision.

MR fluid function

Currently suspensions are mainly filled oil to create a damping force according to the piston speed within the damper. And damping force is proportional to oil viscosity. 

Existing suspension systems cannot continuously change the viscosity of the oil. Thus it is not effectively reducing vibration coming from the road surface of the vehicle.

 

The MR (electrofluidic) suspension has properties that control viscosity depending on the size of the electric and magnetic fields. So it can reduce vibration coming from the road surface of the vehicle depending on changes in external road conditions.
