    摘要: A method of the invention is for controlling an MR-fluid hydraulic mount (12) connected to a vehicle engine. The mount includes an internal MR-fluid cavity (14). The mount includes a partition plate assembly (16) partitioning the cavity into first and second MR-fluid chambers (18,20). The partition plate assembly has an orifice (40) extending from the first MR-fluid chamber to the second MR-fluid chamber. The mount includes an electric coil (42) positioned to magnetically influence the orifice. The method includes, when the vehicle engine is at idle, determining a reference pressure as a fluid pressure within the second MR-fluid chamber. The method includes, when the vehicle engine is above idle, determining a command electric current to be applied to the electric coil using at least a difference between the reference pressure and a current fluid pressure within the second MR-fluid chamber. The method includes applying the command electric output current to the electric coil.

    摘要: A hydraulic mount (10, 110) for automotive engine and powertrain applications includes an elastomer body (12, 112), a base (30, 130) and a partition (24, 124) interposed the body and the base to form a fluid-pumping chamber (22, 122) and a reservoir (37, 137). Circumferentially spaced axial extending holes (52) or slots (53) or an annular orifice track (151) are formed in the partition together with a magnetic coil (54, 154) operable to impose a magnetic field on the holes, slots or orifice track to control the shear properties of a magnetorheological (MR) fluid in the pumping chamber and reservoir. An elastomeric decoupler member (46, 146) is in communication with at least one of the pumping chamber and the reservoir to reduce the mount dynamic stiffness for isolating low-displacement relatively high-frequency vibrations. Vibrations of multiple frequencies may be isolated by tuning the mount with a controller (58, 158).

    摘要: Magnetorheological (MR) fluid dampers are optimized. Dimensional relationships involved in the flow of magnetic flux are related to an operational parametric ratio of magnetic flux density in the fluid to the flux density in the steel. A magnetic valve is utilized to change the flow parameters of the MR fluid and, hence, the operational characteristics of the damper. Several embodiments depicting improved piston designs, including spool as well as toroidal configurations, are disclosed. In addition, both single and twin-tube housing designs are presented, along with several sealless designs. Baffle plates and toroidal magnetic segments interspersed with flow slots are utilized to increase contact between the fluid and the magnetic coil.

    摘要: A tie bar assembly includes front and rear units each including inner inserts interconnected with outer inserts with webs of elastomeric material. A pole sub-assembly is disposed between the units. The pole sub-assembly and the units define front and rear fluid chambers containing a magneto-rheological fluid. Fluid orifices are disposed through the pole sub-assembly for flow of the magneto-rheological fluid between fluid chambers. An electromagnet coil generates an electromagnetic field to affect viscosity of the magneto-rheological fluid. A connecting rod connects inner inserts and is slidably disposed through the pole sub-assembly for causing movement of the magneto-rheological fluid between fluid chambers. A displacement sensor detects movement to generate a signal to the electromagnet coil. Front and rear travel cushions are each disposed on the inner inserts for limiting the movement of the inner inserts toward the pole sub-assembly.
