    摘要: An assembly is provided for fixing the position of an adjustable component (22) of a vehicle, comprising in combination a fixed reference frame (20) within the vehicle such as a dash or a firewall, an adjustable component (22) also disposed in the vehicle such as an adjustable steering column (10), pedals, or a seat. Interconnecting the fixed reference frame (20) and the adjustable component (22) is a fluid locking mechanism (50) which permits selective positioning of the adjustable component relative to the fixed reference frame (20) and holds the adjustable component (22) in position. The fluid locking mechanism (50) is preferably a non-Newtonian flow fluid locking mechanism which uses a magneto-rheological fluid (97) to fix the position of the adjustable component (22) in place once the desired position is selected. To provide additional safety for the vehicle occupants, the fluid locking mechanism may be controlled by an electrical microprocessor (556) or circuit which adjusts the locking strength of the fluid locking mechanism (50) based upon user inputs and dynamic events.

    摘要: A damper device has a magnet (11) and at least two yokes (13) facing the magnet across gaps. The magnet and the two yokes jointly provide a magnetic circuit such that a magnetic flux flowing from a first magnetic pole of the magnet is divided across one of the gaps into magnetic fluxes which flow into entrance sides of the yokes and back from exit sides of the yokes across another of the gaps into a second magnetic pole of the magnet. The two yokes are mechanically connected rigidly to each other, and a spring means elastically holds the one of the gaps between the first magnetic pole and the entrance sides of the yokes. One of the magnet and the yokes is adapted to be connected to a vibratable member. When the gaps are differentially varied in length by vibration of the vibratable member, the divided magnetic fluxes are changed to generate eddy currents in the yokes and the magnetic poles.

    摘要: A magnetically levitated vibration damping apparatus includes a table (11) having a flat board of a magnetic material, an electromagnetic actuator (12) for applying magnetic attractive forces to the flat board to levitate the table (11), a displacement sensor (14) for detecting relative displacement between the flat board and the electromagnetic actuator (12), an acceleration sensor (13) for detecting absolute acceleration of the table (11), and a control system (15) for controlling a current supplied to the electromagnetic actuator (12) based on signals from the displacement sensor (14) and the acceleration sensor (13) according to a first control rule for controlling a gap (Z) between the flat board and the electromagnetic actuator (12) based on the signal from the acceleration sensor (13) and a second control rule for controlling vibrations of the table (11) based on the signal from the acceleration sensor (13), the second control rule including stability control (15) of relative displacement of the table (11).

    摘要: The active damping system (16) includes an electrical current conductive coil (26) spatially fixed with respect to one of the sprung mass (18) and unsprung mass (20) of a vehicle (10) and a magnetic element (28) spatially fixed with respect to the other of the sprung mass (18) and the unsprung mass (20). Relative motion is imparted between the coil (26) and the magnetic element (28) in response to relative motion between the sprung mass (18) and the unsprung mass (20). This relative motion is in response to random input vibrations from a road surface (32). The magnetic element (28) develops a magnetic flux intersecting the coil (26) to develop an induced current through the coil (26) wherein the induced current develops an electromotive force on the magnetic element (28) opposing the relative motion to act as the active damping element (24). The active damping system (16) also includes means (30) for developing a control current through the coil (26) to oppose motion of the sprung mass (18) relative to the road surface (32) occurring below a selected frequency.
