Description
Technical field
The present invention relates to pilot control device performance technical field of measurement and test, particularly relate to a kind of device and method measuring the displacement of pilot control device.
Background technology
Pilot control device (PCU) experiences driver actions, its action is converted to the device that electric signal is sent to flight control computer, whether qualified operation and the flight quality directly affecting pilot of the performance parameter of PCU, and have larger impact to flight safety generation.And the displacement of pilot control device comprises jociey stick displacement and pedal displacement, jociey stick/pedal displacement parameter directly represent pilot and is intended to the manipulation of aircraft, and the measurement of therefore jociey stick displacement seems particularly important.Jociey stick/pedal displacement refers to T point amount of exercise in the horizontal direction, because jociey stick/pedal will cause T point to rotate and in the height change of moving surface in motion process, therefore existing PCU displacement measurement all substitutes jociey stick displacement with the camber line stroke of T point motion, in actual measurement, for the displacement of PCU longitudinal rod, as calculated, when longitudinal rod displacement is 90mm, the movement travel of T point is about 90.6mm; When longitudinal rod displacement is 60mm, the movement travel of T point is about 60.5mm, and the measuring method substituting PCU displacement with the arc of motion lineal travel of T point exists larger systematic error.
Summary of the invention
Technical matters solved by the invention is to provide a kind of device and method measuring the displacement of pilot control device, to solve the shortcoming in above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions:
Measure a device for pilot control device displacement, comprise brace table, guide rail, slide block, connecting rod, bearing, ball spline and displacement transducer; Wherein, brace table is positioned at jociey stick side, and guide rails assembling is on brace table, and connecting rod one end is connected with jociey stick T point, and the other end is connected with ball spline by bearing, and ball spline is arranged on slide block, and slide block is arranged on guide rail; On simultaneous displacement sensor mounting guide rail, and displacement sensor direction is parallel with jociey stick mounting plane.
In the present invention, ball spline is provided with web member, bearing is connected with ball spline by web member.
In the present invention, guide rail is provided with chute, slide block is placed in chute and slides, and is converted into linear displacement, is convenient to displacement sensor for stick motion camber line.
Measure a method for pilot control device displacement, concrete steps are as follows:
1) in jociey stick side, brace table is installed, and by the guide rails assembling with chute on brace table;
2) in one end of connecting rod, bearing is installed, and by bearing, ball spline is connected with connecting rod;
3) by step 2) in the ball spline that installs insert in the slide block be placed on chute;
4) other end of connecting rod is connected with jociey stick T point;
5) installation position displacement sensor on guide rail, and displacement sensor direction is parallel with jociey stick mounting plane;
6) start jociey stick to start working, jociey stick T point drags link motion, and connecting rod drives ball spline to convert the movement in a curve of jociey stick to tangential movement, records jociey stick displacement eventually through displacement transducer.
In the present invention, pedal displacement measurement method is consistent with jociey stick displacement.
In the present invention, during for overcoming stick motion, T point is rotated and in the height change of moving surface, is offset self rotation of T point in stick motion process by bearing, and ball spline is lifted for offsetting jociey stick, T point moves up and down when bowing; Make displacement transducer directly measure PCU displacement, and then improve measuring accuracy, for accurately judging that pilot is intended to the manipulation of aircraft, improving flight safety coefficient, reference frame is provided.
Beneficial effect: in the present invention, jociey stick T point drags link motion, connecting rod drives ball spline to convert the movement in a curve of jociey stick to tangential movement, jociey stick displacement is recorded eventually through displacement transducer, and then raising measuring accuracy, for accurately judging that pilot is intended to the manipulation of aircraft, improve flight safety coefficient, reference frame is provided.
Accompanying drawing explanation
Fig. 1 is the structural representation of preferred embodiment of the present invention.
Embodiment
