The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

摘要： A hydraulic engine mount includes an orifice track formed in a partition between an elastomer body and a base member of the mount, the partition being formed by two separable orifice plates. An annular fluid filled tuning chamber is disposed adjacent the orifice track and separated therefrom by a flexible membrane. An actuator is in communication with the tuning chamber for forcing pressure fluid into or out of the chamber to selectively deflect or distend the membrane to modify the cross sectional area of the orifice track and the vibration damping characteristics of the mount.

摘要： A hydraulic mount assembly includes a body with a main chamber formed therein. A magnetorheological fluid retaining member is positioned in the main chamber forming a magnetorheological chamber adjacent the main chamber. An electrical coil is positioned adjacent the magnetorheological chamber and a plate member is operably connected to the magnetorheological fluid retaining member. Energization and de-energization of the coil controls the ability of the mount to resist movement by varying the apparent viscosity of the fluid within the magnetorheological chamber.

摘要： A hydraulic mount for automotive engine and powertrain applications includes an elastomer body, a base and a partition interposed the body and the base to form a fluid-pumping chamber and a reservoir. Circumferentially spaced axial extending holes or slots or an annular orifice track are formed in the partition together with a magnetic coil 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 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.

摘要： A hydraulic mount for an automotive vehicle or machine includes opposed mounting members secured to an elastomeric body and a base, respectively. An orifice plate assembly is interposed the body and the base to define a pumping chamber and a reservoir for fluid to flow therebetween through an orifice track of the orifice plate assembly. An electroactive polymer decoupler member is secured in a cavity formed between two orifice plates of the orifice plate assembly. The decoupler member is operably connected to a controller for imposing an electric field on the decoupler member to change its shape and thereby selectively vary the dynamic stiffness of the mount.

摘要： A hydraulic engine mount includes opposed mounting members secured to an elastomeric body and a base, respectively, and an orifice plate assembly interposed the body and the base to define a pumping chamber and a reservoir or opposed pumping chambers for fluid to flow therebetween through an orifice track formed by the orifice plate assembly. One or two elastomeric decoupler discs may be secured in recesses between two orifice plates of the orifice plate assembly and form spaces which are operable to be in communication with a vacuum source to impose vacuum pressure on the decouplers at selected frequencies as controlled by solenoid operated valves and a controller. The mount may be operated at a substantially reduced dynamic stiffness lower than the static stiffness of the mount to provide improved low amplitude vibration isolation, in particular.

摘要： A magnetostrictive strain sensor (10) includes a magnetostrictive core (12) comprising a magnetostrictive material, such as a nickel-iron alloy, able to conduct a magnetic flux and whose permeability is alterable by application of a strain. A conductive coil (14) is proximate the magnetostrictive core (12) to generate the magnetic flux when electrically excited. A shell (16) surrounds the conductive coil (14) and the magnetostrictive core (12) for providing a conductive return path for the magnetic flux. An excitation source (18) is electrically connected to the conductive coil (14) for electrically exciting the conductive coil (14) with an alternating current having a constant magnitude. An in-phase voltage circuit (22) is electrically connected across the conductive coil (14). The in-phase voltage circuit (22) senses an in-phase voltage that is in-phase with the alternating current. The in-phase voltage varies correspondingly to the strain subjected to the magnetostrictive core (12). A processor (24) is operatively connected to the in-phase voltage circuit (22) to determine the strain applied to said magnetostrictive core (12) by comparing the in-phase voltage to a predetermined relationship between strain and in-phase voltage.
