Dynamic Vibration Control with Magnetorheological Mounts
Here’s PatSnap Eureka !
Summary
Problems
Hydraulic mounts lack the ability to dynamically modulate their response to stresses over time, limiting their flexibility in adapting to varying operational conditions.
Innovation solutions
A hydraulic mount utilizing a magnetorheological fluid and an electromagnetic system to actively control viscosity in response to magnetic fields, allowing for instantaneous changes in viscosity and dynamic behavior without altering the mount's geometry.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a conventional hydraulic mount with fixed geometry is used, then the mount structure is simple and reliable, but the mount cannot dynamically modulate its response to stresses over time
Why choose this principle:
The patent changes the physical parameter of the fluid (viscosity) in response to external stimuli (magnetic field). The magnetorheological fluid transitions between different viscosity states based on magnetic field intensity, allowing the mount to dynamically adjust its mechanical response without changing its physical geometry or structure.
Principle concept:
If a conventional hydraulic mount with fixed geometry is used, then the mount structure is simple and reliable, but the mount cannot dynamically modulate its response to stresses over time
Why choose this principle:
The patent uses a magnetorheological fluid, which is a composite material consisting of ferromagnetic particles suspended in a carrier fluid. This composite material provides the unique property of being able to change its rheological behavior (viscosity) in response to magnetic fields, enabling dynamic modulation while maintaining a relatively simple mount structure.

Abstract
A mount for damping oscillations comprising: -a first chamber (40) deformable under the action of said oscillations; -a second chamber (5); -a conduit (60) that sets the first and the second chamber (40, 5) into 5 communication. -an incompressible fluid suitable for moving between the first and the second chamber (40, 5) through said conduit (60). The fluid is a magnetorheological fluid. The mount (1) comprises a means (11) for regulating the dynamic behaviour of the mount itself and, in turn, 10 comprising means (12) for generating a magnetic field for exciting the magnetorheological fluid.
