  • Patent number: 11867578
    Abstract: The present invention discloses a high-precision and miniaturized on-orbit calibration device for a six-dimensional force sensor of a space station manipulator and a calibration method thereof, which include an inverted ? shape fixing bracket, three force applying devices, and a cubic stress block. Each force applying device includes a force applying head, a single axis force sensor, a force source part and a fastening part. The force source part includes an upper support plate, a second electrode plate, piezoelectric ceramic plates, a first electrode plate and a lower support plate, which are coaxially arranged sequentially from top to bottom. The single axis force sensor is mounted on the top of the upper support plate, and the hemispherical force applying head is mounted on the top of the single axis force sensor. The cubic stress block is mounted on the top of the six-dimensional force sensor.

  • Patent number: 11650117
    Abstract: The present invention discloses a six-dimensional force sensor with high sensitivity and low inter-dimensional coupling, including a clockwise or counterclockwise swastika-shaped beam, vertical beams, a rectangular outer frame, and strain gauges; the clockwise or counterclockwise swastika-shaped beam includes a cross-shaped transverse beam and four rectangular transverse beams; a center of the cross-shaped transverse beam is provided with several force application holes used for applying forces and moments; four tail ends of the cross-shaped transverse beam are each connected to one of the rectangular transverse beams to form a clockwise or counterclockwise swastika-shaped structure; a top end of a vertical beam is connected to a tail end of a corresponding rectangular transverse beam, and bottom ends of the vertical beams are connected to the rectangular outer frame; and there are a plurality of strain gauges to form six groups of Wheatstone bridges that are respectively used for measuring an X-direction for
