Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to following example.
It is dynamic as the steering wheel of aircraft semi-physical emulation platform (iron bird platform) that steering wheel dynamic load loads simulation test apparatus
State load load maintainer, and assume rudder face load and air speed square be approximated to direct ratio.
As it is shown in figure 1, the steering wheel dynamic load of an embodiment of the present utility model loads simulation test apparatus, bag
Include steering wheel 1,2, two springs of rocking arm 4, two electric expansion bars 5, two blocks 3 and simulation computers
(not shown), the output shaft of steering wheel 1 embeds the hole 22 in the middle of rocking arm 2, and spring 4 is arranged at rocking arm 2 with electronic
Between expansion link 5, simulation computer adjusts electric expansion bar 5 stroke, to change the length of spring 4, passes through
Rocking arm 2 provides dynamic load to steering wheel 1.
Block 3 is arranged at the position of the end of rocking arm 2 when spring 4 is in drift, the end of rocking arm 2 with
The relevant position of block 3 is provided with draw-in groove 21,31, and the first end of spring 4 snaps in the draw-in groove of rocking arm 2 simultaneously
21 fix with electric expansion bar 5 is connected with the draw-in groove 31 of block 3, the second ends of spring 4.
Block 3 does not moves with rocking arm 2.
When steering wheel 1 rotates clockwise, rocking arm 2 left end drives spring 4 to rotate, and rocking arm 2 right-hand member is because hanging spring 4
Draw-in groove 21 opening upwards and have block 3 to limit, therefore right side spring 4 is motionless.When steering wheel 1 rotates counterclockwise,
Situation is contrary.By rocking arm 2 to steering wheel 1 provide that steering wheel 1 clockwise and counterclockwise rotates dynamic
Load.Electric expansion bar 5 can change spring 4 bottom position to be subject to simulate steering wheel 1 to change spring 4 pulling force
Power size.
According to calculating, determine the relation of the rudder face load under a certain basic airspeed and the rudder face degree of bias, and assume this relation
Approximately linear.According to this linear relationship, select to meet the spring 4 of the rigidity of homologous pair sexual relationship, namely spring 4
Rigidity meet the relation of rudder face load under basic airspeed and the rudder face degree of bias.
When emulation, by simulation computer according to the ratio of current emulation air speed square with basic airspeed square, pass through
Calculating is scaled electric expansion bar 5 stroke, namely adjusts the position of spring 4 second end, changes spring 4
Length, enables the active force square equal proportion change according to air speed of spring 4.
When being controlled the rotation of rudder face steering wheel by flight control computer, electric expansion bar 5 can enter through the value that simulation computer calculates
Row is flexible, by change spring 4 tensile elongation apply accurately steering wheel dynamic load to rocking arm 2.Thus reach rudder
Machine 1 simulated aircraft accurately and real-time is load subjected under different flight speeds.
Spring 4, electric expansion bar 5, block 3 are one, and spring 4 is arranged at one end of rocking arm 2, block
3 other ends being arranged at rocking arm 2, provide steering wheel 1 clockwise direction or square counterclockwise by rocking arm 2 to steering wheel 1
To the dynamic load rotated.Such as spring 4 is arranged at the left end of rocking arm 2, and block 3 is arranged at the right side of rocking arm 2
End, when steering wheel 1 rotates clockwise, rocking arm 2 left end drives spring 4 to rotate, and rocking arm 2 right-hand member is because hanging spring 4
Draw-in groove opening upwards and have block 3 to limit, therefore right side spring 4 is motionless, using the teaching of the invention it is possible to provide steering wheel 1 side clockwise
To the dynamic load rotated.
