Abstract

The invention provides an aircraft driving wheel column force sensor which is capable of directly measuring the pushing force and the torsional moment of an aircraft driver on a driving wheel during an aircraft driving process. The aircraft steering wheel column force sensor comprises a driving wheel connection structure, a wheel column force sensor body and a driving column connection structure. The wheel column force sensor body comprises a box body structure which is used for measuring the pushing force and a prism structure which is used for measuring the torque. The box body structure and the prism structure are elastomer. Upper and lower inner surfaces of the box body structure are respectively provided with at least one group of resistance strain gauges. One end of the prism structure is fixed on the upper or lower surface of the box body structure along the axis. A boss and a connection spline are successively arranged on the other end. At least two side walls of the prism structure are respectively provided with at least one group of resistance strain gauges. The box body structure is embedded in a groove arranged in the driving wheel connection structure. The spline is embedded in the driving column connection structure.

Description

technical field [0001] The invention belongs to the field of aviation, in particular to a steering column force sensor for an aircraft. Background technique [0002] Existing measurement methods all use indirect methods to measure the push-pull force and torsion moment applied to the steering wheel by the pilot during the flight of the aircraft. At present, the direct measurement of the push-pull force and torsion moment exerted on the steering wheel by the pilot during the flight of the aircraft is a major technical problem that plagues the entire aviation field. A method or device for pushing and pulling forces and torsional moments applied to the steering wheel during the process. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing measurement methods, and provide a steering wheel column force sensor for an aircraft, which can directly measure the push-pull force and torsion moment applied to the steer...
