Abstract
A system, including a magnetorheological (MR) fluid locking system, including a housing, a piston disposed in the housing, wherein the piston is configured to move axially within the housing, an MR fluid disposed in the housing, an MR fluid pump fluidly coupled to the housing, wherein the MR fluid pump is configured to pump the MR fluid into the housing, and an electromagnet configured to magnetize the MR fluid to control axial movement of the piston.
Claims20
A system, comprising:
- a magnetorheological fluid locking system, comprising:
- a housing;
- a piston disposed in the housing, wherein the piston is configured to move axially within the housing, the piston defining a cavity;
- a magnetorheological fluid disposed in the cavity;
- a magnetorheological fluid pump fluidly coupled to the housing, wherein the magnetorheological fluid pump is configured to pump the magnetorheological fluid into the housing;
- and
- an electromagnet configured to magnetize the magnetorheological fluid to control axial movement of the piston.
