Technical field
This utility model belongs to aero-engine wheel disc experimental technique, particularly relates to the accurate simulation of wheel disc mating surface extruding force load.
Background technology
Fig. 1 is available engine wheel disc local structural graph. Together with wheel disc 1, the ring 2A that obturages are bolted with turbine rear axle 3A. Under engine behavior, by the combined effect of temperature loading Yu centrifugal load, mating surface A place can produce extruding force.
Fig. 2 is the local structural graph of existing wheel disc rotation test part. Transfer panel 2 realizes the connection of wheel disc 1 and equipment axle 3, and in the extruding force of mating surface A place simulated engine duty. But in wheel disc rotation test, the reasons such as load during owing to being difficult to simulation completely to electromotor work, even if mating surface A adopts identical initial engagement tightness in testpieces with motor piece, owing to the relative expansion amount of mating surface A place wheel disc 1 and transfer panel 2 is different under two kinds of duties, cause that the extruding force at mating surface A place also differs. The thickness h of nip and transfer panel 2 top by adjusting mating surface A place, it is possible to mating surface extruding force is adjusted, but is often difficult to fully meet designing requirement, namely simulates the true extruding force load connecting mating surface place less than turbine engine disk.
Summary of the invention
Technical problem to be solved: turbine engine disk can be subject to adjacent wheel disc or the mating surface extruding force of other components applying under working environment, and wheel disc rotation test part may often be such that single-deck testpieces, namely without adjacent disc or other components, also just without corresponding mating surface extruding force. At this time, it may be necessary to design transfer panel, one is the connection realizing wheel disc with testing equipment, and two is the simulation realizing mating surface extruding force. During conventional testpieces design, mating surface place partial structurtes are generally along by the version on electromotor, but transfer panel is generally different with turbine engine disk adjacent disc or the overall structure of component, material, operating temperature. So, mating surface place swell increment being caused different, extruding force is also different, is therefore difficulty with the accurate simulation of mating surface extruding force.
Technical scheme: the transfer panel structure that radial fit face extruding force accurately loads can be realized, including wheel disc 1, transfer panel 2 and equipment axle 3, wheel disc 1 is rotation test part, transfer panel 2 realizes the connection of wheel disc 1 and equipment axle 3, and at mating surface A except applying extruding force load, wherein transfer panel 2 is made up of seam section B, T-shaped crown end, linkage section C and bottom D, and seam section B is by the Base top contact of T-shaped crown end, and the bottom of T-shaped crown end is linkage section C and bottom D. Seam section B is circular, and its meridian section is rectangle; T-shaped crown end is circular, and its meridian section is " T " font; Linkage section C is circular, and its meridian section is rectangle, has several bolts hole on the axial direction of linkage section C, wheel disc 1 and transfer panel 2 is coupled together for installing bolt additional at this; Bottom D is circular, and its meridian section is rectangle, has several threaded hole in its axial direction, transfer panel 2 and equipment axle 3 is coupled together for installing bolt additional at this.
Beneficial effect: the present invention provides a kind of transfer panel structure, by one-parameter Optimal Structure Designing, it may be achieved the accurate simulation of the mating surface extruding force that wheel disc under engine operating environments is subject to, so that wheel disc rotation test result is more accurate.

Detailed description of the invention
The present invention provides a kind of new transfer panel structure, its structure is shown in Fig. 3, the transfer panel structure that radial fit face extruding force accurately loads can be realized, including wheel disc 1, transfer panel 2 and equipment axle 3, wheel disc 1 is rotation test part, transfer panel 2 realizes the connection of wheel disc 1 and equipment axle 3, and at mating surface A except applying extruding force load, wherein transfer panel 2 is made up of seam section B, T-shaped crown end, linkage section C and bottom D, seam section B is by the Base top contact of T-shaped crown end, and the bottom of T-shaped crown end is linkage section C and bottom D. Seam section B is circular, and its meridian section is rectangle; T-shaped crown end is circular, and its meridian section is " T " font; Linkage section C is circular, and its meridian section is rectangle, has several bolts hole on the axial direction of linkage section C, wheel disc 1 and transfer panel 2 is coupled together for installing bolt additional at this; Bottom D is circular, and its meridian section is rectangle, has several threaded hole in its axial direction, transfer panel 2 and equipment axle 3 is coupled together for installing bolt additional at this.
T-shaped crown end can provide centrifugal load, by changing the seam extruding force of its dimensional parameters scalable mating surface A; Fixing structure B realizes the centering to wheel disc 1, simultaneously the extruding force effect when mating surface A place simulated engine works; Linkage section C is connected with wheel disc 1 by bolt; Bottom D is connected with equipment axle 3 by bolt. Relatively conventional structure, the axial location of fixing structure B and radial fit face A (X to) has been carried out Curve guide impeller by the transfer panel 2 of the present invention, the accurate simulation of mating surface A place extruding force effect when can realize after improvement electromotor is worked.
In Fig. 3, on wheel disc 1, ab section is a face of cylinder, and computational analysis shows, under engine operating environments, ab section deforms radiuses such as being frequently not, and namely ab section can be deformed into taper seat, and Fig. 4 is shown in by its deformation schematic diagram. A'b' section in Fig. 4 after the deformation of ab section on note wheel disc 1, it is h1 when transfer panel 2 is positioned at position X1 relative to the radial deformation of wheel disc 1, it is h2 when transfer panel 2 is positioned at position X2 relative to the radial deformation of wheel disc 1, h1 and h2 is unequal, namely mating surface is different from the tightness at A2 place at A1 place, and the extruding force at its mating surface place is also different. Therefore, mating surface A X to diverse location, it is possible to simulate different mating surface extruding forces. And a suitable position can be found so that extruding force effect can be coordinated to the true of wheel disc under engine environmental by accurate simulation at mating surface A place.
Present invention can apply in the rotation test in aero-engine development work.
