    摘要： An active vibration control system (AVCS) and method for reducing motion and/or vibration of a seat frame within an aircraft includes vibration sensors, a controller, and force generators. In some embodiments, the vibration sensors and/or the force generators are attached to the seat frames. In other embodiments, the vibration sensors and/or the force generators are attached to aircraft structures, proximate to the seat frame. By monitoring the motion and/or vibration of the seat frame, the controller calculates a cancelling force to be generated by the force generators to reduce the vibration experienced by the seat frame and its occupant. Such seat frame vibration control can be implemented as a separate AVCS in an aircraft, or can be integrated in an existing AVCS that is also configured to provide vibration control in other parts thereof.

    摘要： A lateral isolator (200) has a tubular body with an upstream end and a downstream end. The lateral isolator (200) also includes an inner member (210) having a pivot ring (220) disposed within the tubular body. A first elastomeric package (236) is disposed between the tubular body and the inner member (210) longitudinally between the pivot ring (220) and the upstream end. A second elastomeric package (236) is disposed between the tubular body and the inner member (210) longitudinally between the pivot ring (220) and the downstream end.

    摘要： Systems and methods for measuring torque on a drive train component of a rotating drive system are disclosed. In some aspects, a system includes a target assembly, a sensor assembly, and a sensor processing unit. The sensor assembly is located proximate to the target assembly, and the sensor assembly includes sensors mounted radially around the shaft and configured to detect sensor targets as the target assembly rotates with the drive train component. The sensor processing unit is configured for receiving sensor signals from the sensor assembly and outputting a torque signal based on the sensor signals. The sensor processing unit is configured for receiving target calibration data for the target assembly and sensor calibration data for the sensor assembly. The sensor processing unit is configured for verifying that the target calibration data corresponds to the target assembly and that the sensor calibration data corresponds to the sensor assembly.

    摘要： A tension-torsion strap includes a first spindle and a second spindle, which are spaced apart from each other, such that the first and second spindles are positioned at opposite ends of the tension-torsion strap, a winding formed of a filament wrapped about the first and second spindles a plurality of turns, the winding extending between and connecting the first and second spindles and being positioned within a cavity formed circumferentially about each of the first and second spindles, and a protective layer covering the winding, which is formed according to an arched winding pattern, a portion of the winding extending outside boundaries of the cavity defined by the inner wall and the lateral walls, such that an outer surface of the winding has an arched, or curved, profile.

    摘要： Torque sensing devices, systems, and methods are capable of measuring and/or determining a torque being transmitted through a shaft by measuring the torsional deformation of the shaft over a short length thereof. Such devices, systems, and devices have a sensor positioned adjacent to the outer surface of the shaft as it rotates, the sensor being positioned to maintain a substantially constant distance between the sensor and the outer surface of the shaft. The sensors may be variable reluctance (VR) sensors rigidly attached to a frame mounted on a bearing (e.g., a hanger bearing), which is mounted on the shaft, such that relative radial motion between the shaft and the VR sensor is minimized (e.g., so that they move in unison). Reducing this amount of motion results in a more accurate torque measurement.

    摘要： Systems and methods for measuring twist on a shaft of a rotating drive system include a first set of targets circumferentially distributed around the shaft at a first axial location to rotate with the shaft and a second set of targets circumferentially distributed around the shaft at a second axial location to rotate with the shaft. The first and second sets of targets are interleaved. The system includes a sensor assembly including one or more sensors mounted around the shaft and configured to detect the first and second sets of targets as the shaft rotates. The system includes a sensor processing unit for receiving an electrical waveform from the sensor assembly, determining, based on the electrical waveform, a twist measurement of twist motion between the first axial location and the second axial location on the shaft, and determining, based on the electrical waveform, a second measurement of shaft motion.
