Description

Technical Field

[0001] The invention relates to the technical field of aviation tire testing, and in particular to an aviation tire dynamic cable passing device and a testing method. Background Art

[0002] When an aircraft tire rolls through a steel cable at high speed during landing, it may cause damage to the tire, or even damage the wheel hub, directly threatening the aircraft's driving safety. To detect the impact of rolling through a steel cable on the tire, the currently public test method is to slowly press the tire against an obstacle in the radial direction, and then observe the deformation and damage of the tire.

[0003] However, the above test method is carried out under static conditions, that is, by pressing the tire radially against the steel cable or steel rod, and does not take into account the influence of the mechanical properties caused by the high-speed rotation of the tire, such as the taper effect and the change of stiffness characteristics, as well as the generation of heading force. These mechanical properties caused by the high-speed rolling of the tire will affect the performance and life of the tire, and this information is the key input for evaluating tire performance and designing the wheel shock absorption system. Therefore, the current test method cannot effectively simulate the actual working conditions of aviation tires landing and passing over cables, and cannot truly reflect the deformation and surface damage of the tires when landing and passing over cables, as well as the dynamic response of the load.

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] like Figure 1 and Figure 2As shown, a preferred embodiment of the present invention provides an aviation tire dynamic cable passing device, which has mutually perpendicular X direction, Y direction and Z direction, and includes a hub wheel device 1, a loading device 2 and a cable passing device 3;

[0042] The loading device 2 includes a loading head 21, a steering device 22, a test wheel 23 and a force measuring device 24. The steering device 22 and the test wheel 23 are arranged on both sides of the loading head 21 along the Z direction. The steering device 22 is used to drive the test wheel 23 to rotate around the axis of the Z direction. The top of the steering device 22 is also connected to a loading cylinder for driving the test wheel 23 to move along the Z direction. The force measuring device 24 is used to monitor and control the radial load of the test wheel 23.

[0043] The hub wheel device 1 comprises a wheel body 11 and a driving member 12, wherein the driving member 12 is used to drive the wheel body 11 to rotate around the axis of the X direction, and the wheel body 11 comprises a first accommodating cavity 111, wherein a test wheel 23 is arranged in the first accommodating cavity 111, and the inner side surface of the wheel body 11 contacts the test wheel 23 to drive the test wheel 23 to rotate;

[0044] The cable passing device 3 includes a cable pushing device 31 and a cable 32 . The cable pushing device 31 is disposed in the first accommodating chamber 111 . The cable pushing device 31 is used to push the cable 32 along the Y direction to the contact area between the wheel body 11 and the test machine wheel 23 .

[0045] Specifically, in conventional tests, the cable-passing test of aircraft tires is static, and it is impossible to explore the influence of the mechanical properties of the tires under high-speed rotation. The test results deviate from the actual situation, and it is difficult to accurately reflect the state of the tires when passing the cable in the actual situation. In reality, it is almost impossible for an aircraft tire to be completely facing the runway, and the steering device 22 in this embodiment drives the test wheel 23 to rotate around the axis of the Z direction, thereby adjusting the horizontal deflection angle of the test wheel 23 relative to the wheel body 11, simulating the cable-passing state of the test wheel 23 under different deflection states, which is more in line with the actual situation, and the test data is more accurate, and it can also meet the test requirements in more different situations. The loading cylinder (not shown in the figure) can adjust the radial load applied by the test wheel 23 to the wheel body 11, thereby simulating the pressure load of aircraft of different weights when landing, and can also better simulate the state of the real aircraft when landing, so that the test results are more real and reliable. In addition, the driving member 12 can drive the wheel body 11 to rotate, and the wheel body 11 drives the test wheel 23 to rotate, so that the test wheel 23 is in a high-speed rotation state when passing the cable, which is more in line with the high-speed rotation state of the actual aircraft tire when landing on the deck of an aircraft carrier, thereby improving the accuracy and reliability of the test results of the test wheel 23 in the cable passing test.

[0046] In some embodiments, the cable passing device 3 includes a support frame 33 and a working platform 34 . The support frame 33 carries the cable pushing device 31 . The support frame 33 is slidably connected to the working platform 34 along the X direction to drive the cable pushing device 31 away from or close to the wheel body 11 .

[0047] Specifically, the cable pushing device 31 is moved on the working platform 34 through the support frame 33. When the test work is not needed, the cable pushing device 31 can be moved out of the first accommodating cavity 111 through the support frame 33 to facilitate on-site operations of the test personnel, such as replacing and adjusting the cable 32, adjusting the structure in the cable pushing device 31, etc., to facilitate subsequent tests.

[0048] like Figure 3 As shown, in some embodiments, the support frame 33 is provided with a removable cross beam 331 and a second accommodating chamber 332, the second accommodating chamber 332 is used to accommodate the test wheel 23, the removable cross beam 331 is arranged on the side of the support frame 33 away from the wheel body 11 along the X direction, and the removable cross beam 331 is used to limit the test wheel 23 in the second accommodating chamber 332.

[0049] Specifically, in the actual testing process, the test wheel 23 is tested in the second accommodating chamber 332. When a test wheel 23 completes the test and needs to be replaced with other test wheels 23, the detachable crossbeam 331 can be removed, and then the loading cylinder lowers the height of the test wheel 23, and the steering device 22 drives the test wheel 23 to rotate out of the second accommodating chamber 332. At this time, the test personnel can remove and replace different test wheels 23. When the test wheel 23 is replaced, the loading cylinder and the steering device 22 drive the test wheel 23 back to the original test station to continue a new round of testing. The entire replacement process of the test wheel 23 is more convenient and quick.

[0050] In some embodiments, the steering device 22 includes a turbine 221 and a worm gear 222. The turbine 221 is transmission-connected to a transmission rod 223 arranged along the Z direction. The end of the transmission rod 223 away from the turbine 221 is horizontally connected to the test wheel 23; the end of the turbine 221 away from the transmission rod 223 is provided with a flange 224 for connecting to the loading cylinder.

[0051] Specifically, in this embodiment, the worm 222 moves linearly, thereby mobilizing the turbine 221 to rotate, and the rotation of the turbine 221 drives the transmission rod 223 to rotate, and then drives the test wheel 23 to rotate around the axis of the Z direction, and the specific connection structure between the turbine 221 and the transmission rod 223 is set inside the loading head 21, and the connection method can be a gear connection, or a belt connection or a chain connection, etc., as long as it can meet the rotation of the turbine 221 to drive the transmission rod 223 to rotate, and its specific transmission structure is no longer repeated here. The output end of the loading cylinder is fixedly connected to the steering device 22 through the flange 224, and then it can drive the turbine 221, the loading head 21, the transmission rod 223 and the test wheel 23 to move up and down along the Z direction, so as to adjust the position of the test wheel 23, and adjust the radial load applied by the test wheel 23 on the inner side of the wheel body 11, so as to simulate the cable passing state of the test wheel 23 under different radial loads.

[0052] In some embodiments, the cable pushing device 31 includes a first guide rail 311, a second guide rail 312 and a cable pushing mechanism 313;

[0053] The first guide rail 311 and the second guide rail 312 are symmetrically arranged on both sides of the support frame 33 along the X direction, and the test wheel 23 is arranged between the first guide rail 311 and the second guide rail 312. The first guide rail 311 and the second guide rail 312 are both sleeved with guide rings 3131, and the cables 32 are fixedly connected between the two guide rings 3131;

[0054] The cable pushing mechanism 313 includes a hinged pushing cylinder 3132 and a push rod 3133. The pushing cylinder 3132 is fixed to the support frame 33. The push rod 3133 is slidably connected to the first guide rail 311 and the second guide rail 312 to push the guide ring 3131 to move along the Y direction.

[0055] Furthermore, both the first guide rail 311 and the second guide rail 312 are arc-shaped structures, and the virtual centers of the first guide rail 311 and the second guide rail 312 coincide with the projection of the center of the wheel body 11 in the X direction.

[0056] Specifically, during the test, the test wheel 23 is located between the first guide rail 311 and the second guide rail 312, and a slidable cable 32 is provided between the first guide rail 311 and the second guide rail 312. When the rotation speed of the test wheel 23 reaches the preset rotation speed, the oil cylinder 3132 is pushed to drive the push rod 3133 to move along the first guide rod, and the push rod 3133 can push the guide ring 3131 to move, thereby driving the cable 32 to contact the test wheel 23, and the test wheel 23 can then throw the cable 32 in the opposite direction of the heading, thereby completing the test of the test wheel 23 passing the cable.

[0057] The first guide rail 311 and the second guide rail 312 are both set as arc structures, which can keep the cable 32 perpendicular to the heading at all times, and except for the contact area between the test wheel 23 and the inner side of the wheel body 11, the cable 32 can always keep a certain distance from the inner side of the wheel body 11, which is the same as the working condition of a real aircraft landing, and can more accurately simulate the real situation and ensure the accuracy of the test results. In addition, the specific distance value between the cable 32 and the inner side of the wheel body 11 can be adjusted according to the needs of the municipal bureau.

[0058] like Figure 4 and Figure 5 As shown, in some embodiments, the cable passing device 3 further includes a buffer mechanism 314 , which is disposed at one end of the first guide rail 311 away from the cable pushing mechanism 313 .

[0059] Specifically, the buffer mechanism 314 includes a support frame 3141, an impact limiting structure and a buffer washer 3142; the support frame 3141 is fixed to the support frame 33, the impact limiting structure includes a buffer pad 3143 provided on the support frame 3141, and the buffer surface of the buffer pad 3143 is perpendicular to the tangent of the first guide rail 311;

[0060] A plurality of buffer washers 3142 are provided and are respectively sleeved on the first guide rail 311 and the second guide rail 312 .

[0061] Specifically, after passing the cable, the test wheel 23 swings the cable 32 to one end away from the cable pushing mechanism 313 until the cable 32 contacts the buffer pad 3143 in the impact limiting structure. The buffer pad 3143 can absorb the impact force of the cable 32 and limit the cable 32 to prevent the cable 32 from flying out and causing damage to surrounding equipment or personnel, while the buffer washer 3142 can abut against the guide ring 3131 to absorb the impact of the guide ring 3131, thereby further limiting the position of the cable 32 and better absorbing the impact of the cable 32.

[0062] In some embodiments, the buffer mechanism 314 also includes a rebound limit structure, which includes a limit plate 3144 and a return spring 3145. The limit plate 3144 is arranged on the side of the buffer mechanism 314 close to the cable pushing mechanism 313. The limit plate 3144 is hinged to the support frame 3141. The two ends of the return spring 3145 are respectively connected to the support frame 3141 and the limit plate 3144. An energy absorption pad 3146 is provided on the side of the limit plate 3144 facing the buffer pad 3143.

[0063] Specifically, after the cable 32 impacts the buffer pad 3143, it may rebound and move in a direction away from the impact limit structure, causing unnecessary trouble. Therefore, an additional rebound limit structure is provided to limit the cable 32 between the rebound limit structure and the impact limit structure. In the actual impact process, the cable 32 first impacts the limit plate 3144, pressing the limit plate 3144 down and compressing or stretching the reset spring 3145. Then, the cable 32 passes over the limit plate 3144 and impacts the buffer pad 3143. At the same time, the limit plate 3144 is reset and bounced up under the action of the reset spring 3145. After impacting the buffer pad 3143, the cable 32 rebounds and hits the energy absorbing pad 3146. The kinetic energy of the cable 32 is absorbed and reduced again until the cable 32 stops.

[0064] In some embodiments, the inner surface of the wheel body 11 is sprayed with an aircraft carrier deck coating. The inner surface of the wheel body 11 is coated with an aircraft carrier deck coating to better simulate the state of staged landing in real situations.

[0065] The present invention also provides an aviation tire dynamic cable test method, comprising the following steps:

[0066] S1, install the test wheel 23 to the loading head 21, and push the cable passing device 3 into the test station in the first accommodating cavity 111 along the X direction, and remove the detachable crossbeam 331 on the support frame 33;

[0067] S2, lowering the test wheel 23 to a first preset height along the Z direction by means of the loading cylinder, and then rotating the test wheel 23 by means of the steering device 22, so that the test wheel 23 is located at the test station of the second accommodating chamber 332 in the cable pushing device 31, and adjusting the deflection angle of the test wheel 23 in the water surface according to the preset yaw angle;

[0068] S3, reinstall the detachable crossbeam 331;

[0069] S4, the force measuring device 24 uses servo feedback to control the loading cylinder to accurately radially load the test wheel 23, so that the test wheel 23 is pressed to the inner side of the wheel body 11;

[0070] S5, the driving member 12 drives the wheel body 11 to rotate, thereby driving the test wheel 23 to a preset rotation angle;

[0071] S6. When the test wheel 23 is accelerated to a preset speed, the cable pushing mechanism 313 pushes the cable 32 to move to the contact area between the test wheel 23 and the wheel body 11;

[0072] S7, the force measuring device 24 collects mechanical data information during the cable passing process of the test wheel 23;

[0073] S8. Stop the test wheel 23 and remove the detachable crossbeam 331. The loading cylinder lowers the height of the test wheel 23 to the first preset height along the Z direction. Then the steering device 22 drives the test wheel 23 to rotate, so that the test wheel 23 is separated from the second accommodating chamber 332. The loading cylinder lifts the test wheel 23 to the second preset height along the Z direction, pushes the cable 32 back to its original position to abut against the push rod 3133, and reinstalls the detachable crossbeam 331.

[0074] In summary, the embodiment of the present invention provides a dynamic cable-passing device and test method for aviation tires. The test wheel 23 is pressed to the inner surface of the wheel body 11 by the loading device 2. The specific loading value can be set according to the test requirements. Then the motor drives the wheel body 11 to rotate and rotate the test wheel 23 to the set landing speed. The cable 32 is pushed into the contact area between the test wheel 23 and the inner surface of the wheel body 11 by the cable-passing device 3. The test wheel 23 will quickly throw the cable 32 in the opposite direction of the heading. Under the guidance of the arc guide rail, the cable 32 always remains perpendicular to the heading. The designed arc guide rail is concentric with the wheel body 11. Therefore, except for the contact area between the test wheel 23 and the inner surface of the wheel body 11, the cable 32 can always maintain a certain distance from the road surface, which is the same as the actual landing condition. The specific distance value can be adjusted according to the actual requirements of the commission. The device has a structural reinforcement in the lateral direction to withstand the taper effect and lateral force when the test wheel 23 rolls at high speed. At the same time, a buffering energy absorption device is designed after the cable 32 is thrown out to protect the safety of the test equipment and the test tire. The loading device 2 can be equipped with a six-component sensor to collect the forces and torques in three directions during the dynamic cable passing process of the aviation tire, providing input for the iterative design of the tire and the design of the landing gear support buffer system.

[0075] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.

11. A method for testing dynamic cable passing of aircraft tires, using the dynamic cable passing equipment of aircraft tires as claimed in any one of claims 1 to 10, characterized in that: The following steps are involved: S1. Install the test wheel to the loading head, push the cable passing device into the test station in the first accommodating cavity along the X direction, and remove the detachable crossbeam on the support frame; S2. Lower the test wheel in the Z direction to a first preset height by means of a loading cylinder, and then rotate the test wheel by means of a steering device so that the test wheel is located at a test station of the second accommodating chamber in the cable pushing device, and adjust the deflection angle of the test wheel in the water surface according to a preset yaw angle; S3, reinstall the removable crossbeam; S4, the force measuring device servo feedback controls the loading cylinder to accurately radially load the test wheel, so that the test wheel is pressed to the inner side of the wheel body; S5, the driving member drives the wheel body to rotate, thereby driving the test wheel to a preset rotation angle; S6. When the test wheel is accelerated to a preset speed, the cable pusher mechanism pushes the cable to move to the contact area between the test wheel and the wheel body; S7, the force measuring device collects mechanical data information during the process of the test machine wheel passing the cable; S8. Stop the test wheel and remove the detachable crossbeam. The loading cylinder lowers the height of the test wheel to the first preset height along the Z direction. Then the steering device drives the test wheel to rotate to make the test wheel leave the second accommodating chamber. The loading cylinder lifts the test wheel to the second preset height along the Z direction, pushes the cable back to its original position to abut against the push rod, and reinstalls the detachable crossbeam.
