Description

Technical Field

[0001] The present invention relates to the technical field of mechanical fatigue testing, and in particular to a thermo-mechanical fatigue test system for high-cycle vibration of turbine blades. Background Art

[0002] The service conditions of turbine blades in aero-engines are harsh. They not only bear alternating mechanical loads and thermal loads, but also bear lateral vibrations of the blades induced by aerodynamic loads and high-cycle vibrations with small amplitudes and high frequencies during service. As one of the core components of aero-engines, the consequences of turbine blade damage are very serious. Therefore, it is of great significance to carry out fatigue tests on turbine blades under complex and extreme working conditions to study their fatigue performance and determine their fatigue life.

[0003] At present, for the fatigue testing of turbine blades in the market, most use electromagnetic vibrators plus fixtures, then fix the turbine blades, and then make the blades vibrate at high frequencies for testing.

[0004] Due to single vertical testing, the obtained results are relatively single. Therefore, during the testing process, operators need to adjust the state of the blades multiple times to obtain fatigue data of the turbine blades at different angles. As a result, the testing process and the time consumed are greatly increased. On the one hand, it affects the data, and on the other hand, during the adjustment process, there will be a situation of bumping, which will cause internal stress in the turbine blades, and then lead to small deviations in the data, thus affecting the overall data.

[0005] Secondly, most of the devices on the market can only operate on a single blade, resulting in a gap between the obtained data and the data of the overall blade installation.

[0006] Therefore, we specifically propose a thermo-mechanical fatigue test system for high-cycle vibration of turbine blades. Summary of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 12 , the present invention provides a technical solution: A thermo-mechanical fatigue test system for high-cycle vibration of turbine blades, including a power supply box 1. The power supply box 1 is used to supply power to devices that use electricity as a whole, such as subsequent drive mechanisms. Moreover, during the test process, it is necessary to paste multiple induction devices and temperature induction devices on the single crystal blade 7 to avoid, so as to obtain the specific situation of the surface fatigue change of the single crystal blade 7.

[0026] The upper end surface of the power supply box 1 is fixedly installed with a hollow frame 2. And at the top of the hollow frame 2 is fixedly installed a flexible connecting pipe 202. The top of the flexible connecting pipe 202 is fixedly installed with a heating cage 203. Secondly, on the upper end surface of the power supply box 1, on both sides of the hollow frame 2 are fixedly installed symmetric first vertical rods 3. Among them, the tops of the two first vertical rods 3 are U-shaped structures, and the second vertical rod 302 is arranged inside. And on the outer side surfaces of the first vertical rods 3 are fixedly installed servo motors 301. The output shafts of the servo motors 301 are fixedly connected to the lower ends of the second vertical rods 302. And the tops of the second vertical rods 302 and the outer side surface of the heating cage 203 are fixedly installed as Figure 2 shown.

[0027] During use, the heating cage 203 heats the temperature to simulate the fatigue situation of the single crystal blade 7 under high temperature conditions.

[0028] Secondly, start the servo motor 301. The output shaft of the servo motor 301 will drive the second vertical rod 302 to rotate. During the rotation of the second vertical rod 302, the heating cage 203 will rotate synchronously. Due to the flexible connecting pipe 202, the heating cage 203 can rotate, so that the top opening of the heating cage 203 can face different angles, and thus the fatigue test of the single crystal blade 7 inside the gas at different angles can be simulated.

[0029] Secondly, a sliding mounting plate 204 is slidably mounted on the inner side of the top of the heating cage 203. A circular through-hole is provided from the upper end face to the lower end face of the sliding mounting plate 204. Secondly, a grid 205 is fixedly mounted on the upper end face of the sliding mounting plate 204 in a circular array. A first motor 206 is fixedly mounted at the center position of the grid 205. A fan blade 207 is fixedly mounted on the output shaft of the first motor 206, as Figure 4 shown.

[0030] During use, start the first motor 206. The output shaft of the first motor 206 will drive the fan blade 207 to rotate. During the rotation of the fan blade 207, the airflow flow condition required by the internal single crystal blade 7 can be simulated, so as to further improve the simulation of the single crystal blade 7, and thus relatively real fatigue test data can be obtained.

[0031] Secondly, a second motor 4 is fixedly mounted on the upper end face of the power supply box 1 inside the hollow frame 2. Mounting plates 5 are arranged on both sides of the second motor 4. A U-shaped mounting frame 404 is arranged on the outer side of the lower end of the mounting plate 5. The outer sides of the openings of the two U-shaped mounting frames 404 are fixedly combined with bolts and nuts, so that the mounting plate 5 and the second motor 4 can be closely combined together, as Figure 5 shown.

[0032] Then, a third motor 501 is fixedly mounted at the middle position on the outer side of the mounting plate 5. A first gear 502 is fixedly mounted on the output shaft of the third motor 501 on the inner side of the mounting plate 5. Secondly, a second gear 503 is fixedly mounted at the upper end on the inner side of the mounting plate 5. The second gear 503 meshes with the first gear 502, as Figure 5 shown.

[0033] During use, start the third motor 501. The output shaft of the third motor 501 will drive the first gear 502 to rotate. During the rotation of the first gear 502, it will drive the second gear 503 to rotate synchronously. It should be noted that during use, the rotation directions of the two second gears 503 need to be the same.

[0034] Secondly, a collar 504 is fixedly installed on the inner upper end surfaces of the two second gears 503. A circular through-hole is formed from the upper end surface to the lower end surface of the collar 504. An annular groove 505 is formed on the inner circumferential surface of the through-hole. A rotating connector 506 is rotatably installed inside the through-hole. Among them, a convex ring 507 is fixedly installed on the outer circumferential surface of the rotating connector 506, and the convex ring 507 is rotatably installed inside the annular groove 505, as Figure 6 shown.

[0035] In addition, during the rotation of the second gear 503, the rotating connector 506 will be driven to rotate synchronously, so as to change the orientation of the rotating connector 506. The orientation of the rotating connector 506 can be consistent with the orientation of the heating cage 203, so as to avoid collisions, so that the single crystal blade 7 can be tilted at an angle or in a horizontal state. Then, under the action of the subsequent first insertion rod 402 and the second insertion rod 403, the rotating connector 506 is rotated. Because during use, the first insertion rod 402 and the second insertion rod 403 can rotate, and, in cooperation with the first insertion hole 401 and the second insertion rod 403, the rotating connector 506 can still rotate in an inclined state.

[0036] Secondly, four first insertion holes 401 are annularly arranged on the upper end surface of the second motor 4. A first insertion rod 402 is slidably installed inside the first insertion hole 401. Second insertion rods 403 are rotatably installed at the upper ends of the first insertion rods 402. Four second insertion holes 508 are evenly annularly arranged on the lower end surface of the rotating connector 506. The upper ends of the second insertion rods 403 are slidably installed inside the second insertion holes 508, as Figure 5 shown.

[0037] During use, when the second motor 4 is started, the output shaft of the second motor 4 will drive the first insertion rod 402 to rotate. During the rotation of the first insertion rod 402, the second insertion rod 403 will be driven to rotate. When the second insertion rod 403 rotates, the rotating connector 506 will be driven to rotate synchronously, so that the single crystal blade 7 can rotate during the subsequent fatigue test, so as to simulate a more realistic use situation, as Figure 2As shown. Therefore, during use, the output shaft of the second motor 4 drives the first insertion rod 402 to rotate through the first mounting hole 401. At this time, due to the rotation of the first insertion rod 402, the second insertion rod 403 will be driven to rotate synchronously. And due to the rotation of the second insertion rod 403, the rotating connector 506 will be driven to rotate. Therefore, during use, the second insertion rod 403 is in a position-changing state during rotation, and thus drives the rotating connector 506 to rotate, thereby being able to drive subsequent rotation. Also, the first insertion rod 402 and the second insertion rod 403 are rotationally connected, so that after subsequent operations, the angle between the positions of the rotationally connected first insertion rod 401 and the second insertion rod 403 will rotate from 180 degrees to less than 180 degrees.

[0038] An electromagnetic vibrator 6 is fixedly installed on the top of the rotating connector 506. A vibrating rod 601 is installed inside the upper end of the electromagnetic vibrator 6. Therefore, during use, the electromagnetic vibrator 6 generates vibrations of different frequencies according to the current situation, and at this time, the vibrating rod 601 will transmit this vibration frequency, as Figure 10 shown.

[0039] A telescopic pump 602 is fixedly installed on the upper end face of the vibrating rod 601. A double-headed connecting rod 603 is fixedly installed on the upper end of the telescopic pump 602. Among them, both ends of the double-headed connecting rod 603 are U-shaped structures, and an L-shaped buckle 604 is rotatably installed inside it. A through groove 605 is opened from the rear end face to the front end face of the lower end of the L-shaped buckle 604. The two end telescopic rods of the telescopic pump 602 are U-shaped structures, and a cylinder is fixedly installed inside the opening of the U-shaped structure, and the cylinder passes through the through groove 605, as Figure 11 shown.

[0040] Therefore, during use, when the telescopic pump 602 is started, the telescopic rod of the telescopic pump 602 drives the L-shaped buckle 604 to rotate. During the rotation of the L-shaped buckle 604, it can clamp the single crystal blade 7 on the upper end face of the double-headed connecting rod 603, so as to be able to conduct high-temperature fatigue tests on a single single crystal blade 7, as Figure 11 shown.

[0041] Secondly, a plurality of support rods 606 are evenly and annularly arrayed and fixedly installed on the outer circumferential surface of the vibrating rod 601. A lower mounting ring 607 is fixedly installed at the upper ends of the support rods 606. An upper mounting ring 608 is fitted and installed on the upper end face of the lower mounting ring 607. Among them, a T-shaped mounting groove 609 is opened at the adjacent ends of the lower mounting ring 607 and the upper mounting ring 608, and the single crystal blade 7 can be installed inside the mounting groove 609, as Figure 12 shown.

[0042] Secondly, six threaded holes 610 are annularly arrayed on the upper and lower end faces of the lower mounting ring 607 and the upper mounting ring 608. A threaded rod 611 is rotatably installed inside the threaded holes 610. Therefore, under the action of the threaded rod 611, the lower mounting ring 607 and the upper mounting ring 608 can be fixedly combined together, so that multiple single crystal blades 7 will not shake or fall, and thus during the operation process, the real overall combination situation of the single crystal blades 7 can be simulated, and real data can be obtained.

[0043] Working principle: First, determine whether to rotate a single single crystal blade 7 or multiple single crystal blades 7. When operating on a single single crystal blade 7, place the lower end of the single crystal blade 7 on the upper end face of the double-headed connecting rod 603.

[0044] Start the telescopic pump 602. The telescopic rod of the telescopic pump 602 drives the L-shaped buckle 604 to rotate, and the upper end of the L-shaped buckle 604 clamps the single crystal blade 7 for operation.

[0045] Then, start the heating cage 203 to adjust the temperature, and adjust the temperature according to requirements. Secondly, start the second motor 4. The output shaft of the second motor 4 drives the first insertion rod 402 to rotate. The first insertion rod 402 drives the second insertion rod 403 to rotate. The second insertion rod 403 drives the rotary joint 506 to rotate. The rotary joint 506 will drive the electromagnetic vibrator 6 to rotate. The electromagnetic vibrator 6 drives the vibration rod 601 to rotate, and the vibration rod 601 drives the single single crystal blade 7 to rotate.

[0046] Then start, start during the rotation process, the electromagnetic vibrator 6. The electromagnetic vibrator 6 transmits the high-frequency vibration frequency to the vibration rod 601, and the vibration rod 601 acts on the single crystal blade 7, so that fatigue test data can be obtained.

[0047] Secondly, start the servo motor 301. The output shaft of the servo motor 301 drives the second vertical rod 302 to adjust the angle. Then, start the third motor 501. The output shaft of the third motor 501 drives the first gear 502 to rotate. The first gear 502 drives the second gear 503 to rotate, and the second gear 503 will drive the collar 504 to rotate. The collar 504 drives the rotary joint 506 to rotate, so that the electromagnetic vibrator 6 can be driven to rotate synchronously, and then the single crystal blade 7 being operated can be driven to adjust the angle.

[0048] Secondly, start the first motor 206. The output shaft of the first motor 206 drives the fan blade 207 to rotate, generating an air flow, and the air flow will flow out from the air outlets 201 on both sides of the hollow frame 2 to form a cyclic operation.

[0049] Secondly, rotate multiple single crystal blades 7 and slidably install the single crystal blades 7 inside the installation groove 609.

[0050] Under the action of the upper mounting ring 608 and the threaded rod 611, fix the single crystal blade 7, and then repeat the above steps.

[0051] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
