摘要： An integrated load sensing system includes a housing including a coupling pin portion thereof. A bridge circuit includes a set of strain gauges bonded to the coupling pin portion. A bridge circuit excitation, error correction, and amplification (BCEECA) subsystem is operatively connected to the bridge circuit for receiving indications of shear load from the strain gauges, correcting signal error, and amplifying the indications of shear load. The BCEECA subsystem provides amplified output signals. A power conditioning module is operatively connected to the BCEECA subsystem for receiving power from an external power supply and conditioning power to an appropriate state for driving the bridge circuit as well as an appropriate state for error correction and amplification circuitry within the BCEECA subsystem. A logic module compares the amplified output signals to a predetermined signal threshold and provides latching of enunciation in accordance with a selected delay after the threshold is surpassed. An enunciation element providing enunciation of the output signals surpassing the signal threshold in accordance with the logic module. The bridge circuit, the BCEECA subsystem, the power conditioning module, the logic module, and the enunciation element are contained and sealed within the housing. The invention includes a method for in situ testing of a shear load sensing system for a mechanical system.

摘要： An actuator assembly configured to control the movement of a stabilizer includes a ball screw having a longitudinal axis and configured to be rotated by a drive assembly, a primary nut assembly coupled to the stabilizer and received on the ball screw such that rotation of the ball screw causes movement of the primary nut assembly along the longitudinal axis of the ball screw, the ball screw and primary nut defining a primary load path between the between the drive means and the stabilizer, and a secondary nut assembly coupled to the primary nut assembly and configured to engage the ball screw upon failure of the primary load path. The secondary nut assembly comprising a split nut assembly having opposing halves extending about the ball screw, the split nut having at least one outer cam surface along the outer surface of one of the halves; and a secondary nut housing extending about the split nut; wherein upon failure of the primary load path, rotation of the outer cam surface is configured to move the split nut into locking engagement with the ball screw.
