Technical field
The utility model relates to flight control system Hardware-in-loop Simulation Experimentation, is specifically related to a kind of steering wheel hinge moment charger.
Background technology
The rudder face of aircraft is handled by steering wheel, and in the time of control surface deflection, the aerodynamic force that air-flow produces forms aerodynamic moment to rudderpost, and this moment is commonly referred to hinge moment.Hinge moment is very large on the impact of steering wheel, and its variation certainly will cause the variation of steering wheel dynamic perfromance, even destroys the characteristics of motion of steering wheel.Therefore in the time flying to control Hardware-in-loop Simulation Experimentation, steering wheel is carried out to hinge moment load test and be necessary.
It is generally the one test in steering wheel development process that steering wheel hinge moment loads, and not yet finds that relevant steering wheel hinge moment is loaded in flight control system semi-matter simulating system.
Utility model content
The utility model provides a kind of steering wheel hinge moment charger, the hinge moment loading problem to steering wheel while carrying out flight control system Hardware-in-loop Simulation Experimentation to solve.
A kind of steering wheel hinge moment charger, is characterized in that comprising support, base, bearing seat, tension-compression sensor, and sensor Pressure Block, loads operating bar, bearing, coupling shaft, start motor; Support is arranged on base, start motor is fixed on support top, between motor and loading object coupling shaft, be provided with S shape tension-compression sensor, tension-compression sensor upper end is provided with Pressure Block, lower end is used coupling bolt to be connected with bearing seat, coupling shaft one end is connected to steering wheel, and other end connection bearing is also combined into one with bearing seat, and bearing seat and tension-compression sensor are cantilever position; When test, steering wheel carries out work by flight control program, charger drives start motor to load by the load of each characteristic point of trajectory by control program, load is loaded into Pressure Block by loading operating bar, be delivered on steering wheel through tension-compression sensor, bearing seat, bearing, coupling shaft, realize the hinge moment loading procedure of simulation steering wheel under state of flight.
The utility model utilizes programme controlled start motor to load the steering wheel that flies to control Hardware-in-loop Simulation Experimentation, the load one of load and each characteristic point of trajectory to, can simulate more realistically the serviceability of steering wheel under state of flight, test findings is more reliable.

Embodiment:
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of steering wheel hinge moment charger, as Fig. 1, shown in Fig. 2, comprise support 1, spacing fixture block 2, base 4, spacer pin 6, bearing seat 7, tension-compression sensor 9, sensor Pressure Block 10, load operating bar 11, bearing 12, coupling shaft 13, start motor 14, support 1 is arranged on base 4, start motor 14 is fixed on support 1 top, as shown in Figure 2, between motor and loading object coupling shaft 13, be provided with S shape tension-compression sensor 9, tension-compression sensor 9 upper ends are provided with Pressure Block 10, lower end is used coupling bolt 8 to be connected with bearing seat 7, coupling shaft 13 one end are connected to steering wheel, the other end is installed bearing 12 and is combined into one with bearing seat 7.So can realize steering wheel in loading hinge moment can rotate by testing requirements.After installing, bearing seat 7 is cantilever position with tension-compression sensor 9.Start motor 14 is load input source, the size of load is controlled by the control program of motor, the load of its input acts on Pressure Block 10 by the loading operating bar 11 on it, be delivered on bearing seat 7 through tension-compression sensor 9, in load transmittance process, pressure sensor 9 can measure the load data of start motor 14 true inputs, for checking the load that loading motor 14 is inputted, warranty test rigorous.
When steering wheel work drives coupling shaft 13 to rotate, likely make coupling shaft 13 cantilever end whippings.For avoiding this kind of situation, bearing seat 7 both sides mounting limit pins 6, by spacer pin 6 be arranged on spacing fixture block 2 on support 1 by the position limitation of bearing seat 7 in support 1, between spacer pin 6 and spacing fixture block 2, be clearance fit, while guaranteeing to load, bearing seat 7 can carry out certain displacement on loading direction.
While test, steering wheel carries out work by flight control program, and charger drives start motor 14 to load by the load of each characteristic point of trajectory by control program.Load is loaded into Pressure Block 10 by loading operating bar 11, is delivered on steering wheel through tension-compression sensor 9, bearing seat 7, bearing 12, coupling shaft 13, realizes the hinge moment loading procedure of simulation steering wheel under state of flight.
The just embodiment of this utility model that instructions is described, the various not fleshes and bloods to utility model that illustrate are construed as limiting, person of an ordinary skill in the technical field read after instructions can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
