  • Patent number: 10317323
    Abstract: Systems and methods of operating a test apparatus to simulate testing a production aircraft component include assembling a test assembly having a test specimen and a wear protection material disposed on opposing sides of the test specimen, an outer plate disposed on each side of the test specimen in contact with the wear protection material, and a bolt disposed through the test specimen and the outer plates and applying a preload against the wear protection material. The test assembly is secured in a test machine, and the test machine is operated to provide a predetermined displacement of the test specimen relative to the outer plates at a predetermined frequency at a determined frequency of displacement cycles. The preload, the predetermined displacement, and the predetermined frequency of displacement cycles are determined through finite element analysis of an analytical model of the production component.

  • Patent number: 10288504
    Abstract: The present invention provides an axial rotary type torque sensor comprising a planetary gear set disposed along a central axis between an input shaft and an output shaft.

The ring gear is connected with a plurality of strip-like beams. At least one strain gauge is attached to the beams. One ending portion of the beam is fixed and the other ending portion is used for bearing a tangential force applied on the ring gear to generate a deformation at a rotation direction of a circumference. A strain gauge which senses the strain of the deformation used as a torque sensing value between the input shaft and the output shaft, thereby improving the poor sensing accuracy and sensitivity of the conventional torque sensors and solving the problem that the radial volume cannot be effectively reduced.
