The limitation of scope.
As shown in Figure 1 to Figure 2, a kind of flying tail flutter model rotary gap simulator, including：Horizontal tail flutter model
1st, shaft 2, the first fixture block 3, the second fixture block 4, spring pedestal 5 and manipulation spring 6；
2 one end of shaft is connected with horizontal tail flutter model 1, and the other end is connected with test base, and shaft 2 is around horizontal tail flutter model
1 rotates；
Spring pedestal 5 is provided with annular mounting portion, and annular mounting portion, which stretches out, extends and be provided with spring mountings, ring
Bearing is provided with shape mounting portion, the annular mounting portion of 5 one end of spring pedestal is socketed in shaft 2 by bearing, its other end
The free end of the spring mountings manipulation spring 6 that is fixed on test base with one end be connected；
Annular is installed in shaft 2 respectively for first fixture block 3 and the second fixture block 4, both the first fixture block 3 and the second fixture block 4 shapes
Into having the function of adjustable installation gap；
Spring pedestal 5 close to one end of shaft 2 along shaft 2 it is axially extending go out a boss 7, boss 7 be installed on first card
In the installation gap formed between 3 and second fixture block 4 of block；
The rotation of horizontal tail flutter model 1 promotes shaft 2 to drive the first fixture block 3 and the second fixture block 4 as shaft 2 is moved together,
After the first fixture block 3 and the second fixture block 4 collide boss 7, spring pedestal 5 is driven to overcome the elastic force reciprocally swinging for manipulating spring 6.
In the present embodiment, both the first fixture block 3 and the second fixture block 4 are arc-shaped, both one end convex to form screens portion respectively,
Screens portion can form boss 7 effective limit stop effect, and the first fixture block 3 and the second fixture block 4 are adjusted by bolt and be installed on
On the side wall of shaft 2, and installed in the both sides of boss 7.
In the present embodiment, the first fixture block 3 is bolted on the side wall of shaft 2, and the second fixture block 4 is adjustable to be installed on
On first fixture block 3, the number of openings of 2 side wall of shaft can be reduced, keeps the good integrality of shaft 2, improves the structure of shaft 2
Intensity.
It is appreciated that：Second one end of fixture block 4 away from its screens portion is along between bending direction of the extension of its body etc.
Away from multiple screw mounting holes are set, the first fixture block 3 sets the mounting hole for coordinating installation with the second fixture block；
By selecting 3 attachment screw mounting hole of the second fixture block 4 and the first fixture block, 4 phase of the first fixture block 3 and the second fixture block is adjusted
For the gap between boss 7；
After adjustment, the second fixture block 4 is fixed on the first fixture block 3 by screw, since the 3rd fixture block 3 passes through its card
The mounting hole that position portion is set is fixed in shaft 2, so the first fixture block 3 and the second fixture block 4 can rotate together with shaft 2.
The present invention adjusts rotary gap by the relative position in the rotation direction of the first fixture block 3 and the second fixture block 4
Size, realizes the change of gap size, meets test requirements document.
