Abstract

The embodiment of the invention discloses a torsion-tension relationship measuring device and method for an aircraft hinge structure. The torsion-tension relationship measuring device comprises a hinge structure and a torsion-tension relationship measuring module; in the hinge structure, a bolt penetrates through a double-lug structure and a bearing, and the threaded end of the bolt is screwed andfixed through a nut; and, in the torsion-tension relationship measurement module, a stop chuck and a force bearing baffle are provided with through holes for bolts to penetrate through, one end of arotating shaft is fixedly connected with a motor, the other end of the rotating shaft is fixedly connected with a nut sleeve, a port of the nut sleeve is clamped on a nut of a hinge structure, and aninput torque sensor is arranged on the rotating shaft. The bolt further penetrates through the stop chuck and the force bearing baffle, the bearing baffle, a bolt head is fixed through the stop chuck, the force bearing baffle makes contact with the side, close to the bolt head, of the double-lug structure, and the force bearing baffle and the stop chuck are connected with the torque and tension sensor. According to the embodiment of the invention, the problem of measurement of the torsional-tensile relationship of the typical hinge structure is solved, and the torsional-tensile relationship of the typical hinge structure can be effectively measured.

Description

Technical field [0001] This application relates to, but is not limited to, the technical field of hinge structure torque and tension measurement, in particular to a device and method for measuring the torsion relationship of an aircraft hinge structure. Background technique [0002] The typical hinge structure is generally used for the connection between the movable wing surface of the aircraft and the fixed support arm, which is an important connection of the aircraft. The bolts in the hinge structure have an appropriate pre-tightening force, which not only ensures the reliability of the connection, but also improves the fatigue performance of the hinge structure. Therefore, measuring the torsion relationship of a typical hinge structure is the core technology of tightening axial force control. [0003] Although the measuring device and measuring method of the torsion relationship of the thread structure have been proposed. However, the existing measuring devices and measuring m...
