摘要： Systems and methods for measuring a clearance between a rotating machine component and a sensor unit are disclosed. In some aspects, a system includes a sensor unit oriented to detect the rotating machine component as the rotating machine component rotates past the sensor unit, the sensor unit including at least a first sensing element and a second sensing element spaced apart from the first sensing element. The system includes a sensor processing unit in electrical communication with the sensor unit. The sensor processing unit is configured for receiving a first waveform from the first sensing element; receiving a second waveform from the second sensing element; and determining, based on a comparison between the first waveform and the second waveform, a distance between the blade tip and the sensor unit.

摘要： A combined brake and motor providing tactile feedback control to a human-machine interface steering input device as part of a steer-by-wire system is provided. The brake is a tactile feedback device (TFD) brake and the motor is an electric motor coupled to the brake. The brake provides end stop control and resistive torque to the steer-by-wire system. The motor provides motion control to the steer-by-wire system, where motion control includes a return-to-center, a command following, an on-center control, an active force-feel, and/or a warning mode (e.g., similar to an aircraft stick shaker or a lane departure). The steer-by-wire system is an active system.

摘要： In a multi-stage torsional coupling and associated methods of providing variable stiffness, the coupling has an inner member connected to a first torsional connection, a sprocket plate connected to the inner member, one or more plates connected to a second torsional connection, an outer member rigidly attached to the one or more plates, and a plurality of damping stages arranged for sequential engagement by movement of the sprocket plate relative to the one or more plates to provide a variable stiffness over a angle of angular displacement for the multi-stage torsional coupling. The sprocket plate is rotatable relative to the one or more plates to sequentially engage the plurality of damping stages to provide stiffness between the first and second torsional connections that increases in a non-linear, or stepped, manner as the amplitude of the angular displacement of the sprocket plate relative to the one or more plates increases.

摘要： A one-part adhesive including a grafted phenoxy resin, a polymaleimide compound, an organic carbonate, and an optional silane adhesion promoter is described. More particularly, the grafted phenoxy resin includes carboxylic acid and acrylate ester functionality. Methods of using adhesives to bond a thermoplastic urethane to a rigid substrate, e.g., in an injection or compression molding process, are also described.

摘要： Systems and methods for measuring displacement parameters of rotating shafts and couplings are disclosed. In some aspects, a measurement system includes a shaft extended in a longitudinal direction and a target wheel configured to rotate with the shaft. The target wheel includes sensor targets circumferentially distributed around the target wheel. Some of the targets are slanted in the longitudinal direction and some of the targets are parallel to the longitudinal direction. The measurement system includes a sensor array including at least three sensors mounted radially around the shaft and configured to detect the sensor targets as the target wheel rotates with the shaft. The measurement system includes a controller configured to receive sensor signals from the sensors and determine, based on the sensor signals, at least an axial displacement measurement of the shaft in the longitudinal direction and a radial displacement measurement of the shaft.

摘要： Actuators are components of machines, which move and/or control a mechanism or system. During operation, actuators can experience regeneration events, with the actuator actually generating excess energy (e.g., regenerative energy) which must be stored or dissipated to avoid damaging the power supply. An actuator motor controller is configured to implement field oriented voltage control and flux weakening voltage control without current sensors. Dissipating regenerative energy includes providing a motor controller to command a motor drive to modify an input voltage, or to dissipate regenerative energy in a dump circuit. This command can cause motor windings to dissipate regenerative energy. Systems having a plurality of actuators distribute regenerative energy from one actuator to another. A central controller provides centralized regeneration dissipation control for the plurality of actuators. A power distribution unit includes a dump resistor to dissipate regenerative energy in addition to or instead of in the actuators.

摘要： Dampers (100), assemblies, and methods are provided for lead-lag damping for an articulated rotor and includes a lead-lag damper (100) having a first end connector (102) configured to be coupled to a rotor hub (H), a second end connector (104) configured to be coupled to one of a plurality of rotor blades (B), and a body portion (110) coupled to the first end connector (102) and to the second end connector (104). The body portion (110) includes one or more elastomeric material layers (120) arranged in a lengthwise direction between the first end connector (102) and the second end connector (104), with each of the elastomeric material layers (120) having a substantially chevron-shaped profile in a crosswise direction.

摘要： A magnetically-responsive device (100) having a magnetic seal (160,170) to retain magnetically responsive material within a defined space (150) is provided. The magnetically-responsive device (100) has a shaft (110), a rotor (130), a magnetic field generator (145), a magnetically-responsive medium and a magnetic seal (160,170). The seal (160,170) is preferably a non-contact seal (160,170) that does not deteriorate over time and generates little to no resistance.

摘要： Circular force generator devices (100), systems, and methods for damping vibrations which include two complementary rotor assemblies (110, 120) that are rotatable together about a common shaft (102) but that have an adjustable rotational position (P1, P2) with respect to one another such that a significant reduction in rotor inertia and bearing drag relative to conventional CFG configurations is provided. The present architecture creates virtually zero rotating moment.

摘要： Compliant mounting systems, devices, and methods for mounting a vehicle engine to a vehicle structure or base include a top mount, a lower mount, a center trunnion mount, and an aft mount which are configured to react forces transmitted by the engine to the vehicle structure. Metallic and elastomeric elements can provide vibrational and force isolation characteristics. Stops (e.g., snubbing elements) allow for a specific range of motion before internal mount structures contact each other to act as a conventional hard mount. Fluid elements and compressible gas-filled spaces/bladders may be incorporated to provide fluid damping behaviors to complement the metallic and elastomeric elements.
