Description

Technical Field

[0001] This invention belongs to the field of aerospace component performance testing technology, and in particular relates to a multi-service condition composite loading device for additive manufacturing support components of aero-engines. Background Technology

[0002] Large support components manufactured using additive manufacturing for aero-engines are core load-bearing parts of the aero-engine and the entire aircraft, directly determining the operational reliability of the aero-engine and the flight safety of the entire aircraft. Additive manufacturing, with its advantages of integrated molding of complex structures and manufacturing of large-size components, has become the mainstream processing method for large support components in aero-engine additive manufacturing.

[0003] However, the inherent characteristics of additive manufacturing processes make it difficult to accurately control the quality of components. Problems such as internal porosity, weak interlayer bonding, and uneven microstructure are prominent. The mechanical performance stability is lower than that of traditional forged and cast components, and the risk of failure during service is higher. Before service, comprehensive and rigorous mechanical verification must be carried out through strength tests to avoid potential safety hazards in advance.

[0004] When large additively manufactured support components for aero-engines are in service, they are subjected to extremely complex stress environments, simultaneously bearing multiple loads such as axial thrust, circumferential torque, radial tension and compression, bending moment, asymmetric eccentric loading, instantaneous impact, and interlaminar shear, with a wide variety of complex combinations of operating conditions. Therefore, it is essential to utilize loading devices to achieve multi-load composite simulation, full-condition coverage, and accurate reproduction of the component's actual service stress state.

[0005] However, at present, the industry lacks a dedicated loading device for large support components in the additive manufacturing of aero-engines. Existing loading devices are generally developed for traditional small forgings and castings, which have the disadvantages of single load loading and incomplete working condition coverage. Even if a few loading devices have multi-load loading capabilities, they are only suitable for small standard parts and cannot meet the special needs of large additive components with large size, complex irregular structure and high value verification. They also cannot simulate the working conditions of additive components such as layered stress and interlayer shear, and it is even more difficult to achieve multi-degree-of-freedom composite loading and non-stop working conditions switching.

[0006] Due to the limitations of existing loading devices, high-value additive support components cannot undergo comprehensive and reliable strength verification, which severely restricts the safe application of additive manufacturing technology in core and valuable components of aero-engines.

[0039] The following describes a single use of the present invention with reference to the accompanying drawings: When an axial thrust reverse load needs to be applied to the aero-engine additive manufacturing support component 4 via the left loading disk 2 / right loading disk 3, the single power output motor 9 is started, and the thrust reverse loading transmission clutch 10 is engaged. The driving force of the single power output motor 9 is transmitted sequentially through the thrust loading transmission clutch 10, the thrust reverse loading transmission shaft 11, the thrust reverse loading reversing double bevel gear set 12, the thrust reverse loading transmission shaft 13, and the thrust reverse loading friction torque limiter 14 to the thrust reverse loading transmission lead screw shaft 15. The rotational motion of the thrust reverse loading transmission lead screw shaft 15... The linear motion of the reverse thrust loading nut 19 will be converted into synchronous linear motion, which will drive the transmission wheel shaft 21 and the guide pulley 20 to move linearly. At this time, the linear motion of the guide pulley 20 will be converted into linear motion of the reverse thrust loading slide 16 along the reverse thrust loading groove 18 through the force transmission of the reverse thrust loading guide inclined hole groove 22. The reverse thrust loading slide 16 will apply axial reverse thrust load to the left loading disk 2 / right loading disk 3. The axial reverse thrust load on the left loading disk 2 / right loading disk 3 will finally act on the aero-engine additive manufacturing support component 4.

[0040] When a torsional load needs to be applied to the aero-engine additive manufacturing support component 4 via the left loading disk 2 and right loading disk 3, the single power output motor 9 is started, and the first branch drive connecting clutch 25 is engaged. The driving force of the single power output motor 9 is sequentially transmitted through the branch drive connecting double spur gear set 23, the branch drive connecting drive shaft 24, the first branch drive connecting clutch 25, the first branch drive connecting reversing three bevel gear set 26, the loading disk torsional transmission gear set 29, the loading disk torsional loading transmission spur gear 30, and the loading disk torsional loading transmission... The load is transmitted from shaft 31, torsional loading friction torque limiter 32, worm shaft 33, and worm wheel 34 to torsional loading shaft 35. This torsional loading shaft 35 drives torsional loading force transmission block 36 to rotate synchronously. Under the combined action of torsional loading force transmission block 36 and torsional loading force transmission groove 53, the resulting torsional load is applied to the left loading disk 2 / right loading disk 3 through loading force transmission ring 52. The torsional load on the left loading disk 2 / right loading disk 3 ultimately acts on the aero-engine additive manufacturing support component 4. Furthermore, by adjusting the gear position of the electromagnetic paddle-driven sliding dog-tooth clutch sleeve within the first branch transmission connection reversing three-bevel gear set 26, the rotation direction of the torsional loading shaft 35 can be changed, thus enabling the application of torsional loads under different rotation direction conditions.

[0041] When radial tensile load needs to be applied to the aero-engine additive manufacturing support component 4 via the left loading disk 2 and right loading disk 3, the single power output motor 9 is started, the second branch transmission connection clutch 27 is engaged, and the driving force of the single power output motor 9 is sequentially transmitted through the second branch transmission connection reversing three bevel gear set 28, the loading disk radial tensile loading transmission gear set 37, the loading disk radial tensile loading transmission spur gear 38, the loading disk radial tensile loading transmission shaft 39, the loading disk radial tensile loading friction torque limiter 40, and the loading disk radial tensile loading transmission shaft 41 to the first branch loading disk radial tensile screw 43 and the second branch loading disk radial tensile screw 43. The rotational motion of the radial tension screw 45 of the first branch loading plate, the radial tension screw 43 of the first branch loading plate, and the radial tension screw 45 of the second branch loading plate are synchronously converted into the linear motion of the radial tension nut lever 44 of the first branch loading plate and the radial tension nut lever 46 of the second branch loading plate, and the motion directions are exactly the same. Therefore, under the cooperation of the radial tension transmission groove 54 and the radial tension lower transmission groove 55, the generated radial tension load is applied to the left loading plate 2 / right loading plate 3 through the loading transmission ring sleeve 52. The radial tension load on the left loading plate 2 / right loading plate 3 is finally applied to the aero-engine additive manufacturing support component 4. In addition, by simply adjusting the gear position of the electromagnetic paddle-driven sliding dog-tooth clutch sleeve in the reversing three-bevel gear set 28 of the second branch transmission, the rotation direction of the radial tension loading transmission shaft 41 of the loading plate can be changed, thereby changing the motion direction of the radial tension nut lever 44 of the first branch loading plate and the radial tension nut lever 46 of the second branch loading plate, and finally achieving the application of radial tension load under different motion direction conditions.

[0042] When axial translation and attitude adjustment of the aero-engine additive manufacturing support component 4 are required, the first slide drive motor 63 and the second slide drive motor 67 are started simultaneously, with both rotating at the same speed and in the same direction. This drives the first slide drive screw 64 and the second slide drive screw 68 to rotate at the same speed and in the same direction, causing the first slide drive nut slider 65 and the second slide drive nut slider 69 to move at the same speed and in the same direction. This, in turn, drives the first slide drive rack 66 and the second slide drive rack 70 to move at the same speed and in the same direction. The slide drive spur gear 71 is positioned relative to the first slide drive rack 66. The second slide drive rack 70 remains stationary and follows the movement, then drives the slide drive force transmission shaft 72, the side loading force transmission slide 61, the clamp guide slide seat 60, the clamp guide slide frame 59, the clamp 58 and the side loading slide 57 to translate along the loading slide guide rail 77. The side loading slides 57 in the left and right composite loading actuators move at the same speed and in the same direction, ultimately driving the aero-engine additive manufacturing support component 4 to perform axial translation and attitude adjustment, which is used to compensate for the processing and assembly errors of the component during the installation stage.

[0043] When it is necessary to apply an axial bending moment load to the aero-engine additive manufacturing support component 4, the execution process is the same as when the aero-engine additive manufacturing support component 4 is axially translated and adjusted. The only difference is that the side loading slide 57 in the left composite loading actuator and the side loading slide 57 in the right composite loading actuator move in opposite directions or in the same direction with differential speed, thereby generating a bending moment in the aero-engine additive manufacturing support component 4 to simulate the asymmetric thrust of the two engines.

[0044] When a radial compressive load needs to be applied to the aero-engine additive manufacturing support component 4, the first slide drive motor 63 and the second slide drive motor 67 are started simultaneously, with the same speed but opposite directions. This drives the first slide drive screw 64 and the second slide drive screw 68 to rotate in opposite directions at the same speed, causing the first slide drive nut slider 65 and the second slide drive nut slider 69 to move in opposite directions at the same speed. This, in turn, drives the first slide drive rack 66 and the second slide drive rack 70 to move in opposite directions at the same speed. The slide drive spur gear 71 only rotates in place relative to the first slide drive rack 66 and the second slide drive rack 70, thereby driving the slide... The seat drive transmission shaft 72 drives the clamp sliding drive spur gear 75 to rotate synchronously. The rotational motion of the clamp sliding drive spur gear 75 is synchronously converted into the linear motion of the clamp sliding drive rack 76, which in turn drives the clamp guide slide frame 59 to perform linear motion synchronously. This generates a radial compressive load on the side loading slide 57 through the clamp 58. The radial compressive loads on the side loading slides 57 in the left and right composite loading actuators are opposite in direction and face each other. Finally, the radial compressive load is applied to the aero-engine additive manufacturing support component 4 through the side loading slide 57 to simulate instantaneous impact conditions such as bird strikes.

[0045] All of the above loading modes can be applied individually or in any combination. Parameters such as loading force, loading direction, loading rate, and loading displacement can be flexibly adjusted to meet the simulation of complex service conditions. It can comprehensively cover the main stress forms that the aero-engine additive manufacturing support component 4 may encounter in the actual flight envelope.

[0046] The solutions in the embodiments are not intended to limit the scope of protection of the present invention. All equivalent implementations or modifications that do not depart from the present invention are included in the scope of protection of the present invention.
