Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0035] Embodiment 1
[0036] Figure 1 It shows a three-dimensional structural diagram of the cable-passing test equipment of the aviation tire 11 in this embodiment; Figure 2 A partial enlarged view of the cable-passing test equipment for the aircraft tire 11 in this embodiment is shown; Figure 3 The structure diagram of the cable passing device 20 in this embodiment is shown;
[0037] Figure 4 A schematic structural diagram of the cable passing device 20 in an embodiment of the present invention is shown with a partial outer frame removed.
[0038] It is worth noting that Figure 1-4 , the variable cross-section steel cable 21 is in the initial position and the final position, wherein the variable cross-section steel cable 21 is in the initial position when it is not in contact with the aircraft tire 11, that is, the variable cross-section steel cable 21 is in the initial position when it is in the extended state. The variable cross-section steel cable 21 is in the final position when it is in contact with the limit clamp 24 after being rolled by the tire, that is, the variable cross-section steel cable 21 is in the final position when it is in the stored state.
[0039] like Figure 1-4As shown, this embodiment provides an aviation tire 11 cable-passing test equipment, which is mainly used for cable-passing tests on the wheels of carrier-based aircraft, namely, the aviation tire 11 in the text. Specifically, in the aviation field, wheel cable-passing is one of the important dynamic tests that must be conducted to verify the quality, performance and life of the aviation tire 11, and it is also an important guarantee for ensuring the safety of cable-passing and taxiing of carrier-based aircraft. At present, there is no special tire dynamic cable-passing test equipment in China. The common method is to press the tire on a steel pipe for static loading, so as to obtain simple test results and data, but it is impossible to fully and correctly evaluate the quality and life of the tire.
[0040] The cable-passing test equipment for the aircraft tire 11 in this embodiment arranges multiple test components, conducts tests under conditions that truly simulate the use conditions, and collects test data during the test, and finally completes the wheel cable-passing test. Specifically, the cable-passing test equipment for the aircraft tire 11 in this embodiment specifically includes a tire rolling simulation device 10, a sensor test device, a control device, and a cable-passing device 20.
[0041] The tire rolling simulation device 10 includes an aircraft tire 11 and a pavement simulation component 12. The aircraft tire 11 is a wheel for an aircraft. In this embodiment, the aircraft tire 11 is simulated by the pavement simulation component 12 to perform wheel sliding simulation, and finally simulates the rolling speed and inertia force of the wheel during normal use. The pavement simulation component 12 drives and controls the pavement simulation flywheel 122 through a control device. Through the rolling of the flywheel, a runway surface is formed on the inner side surface. After contacting the aircraft tire 11, it drives the aircraft tire 11 to roll, simulating a real scene of an aircraft landing. The tire rolling simulation device 10 obtains a real simulation environment through the pavement simulation component 12, and is used as a simulation device in the test equipment to drive the aircraft tire 11 to roll and provide a simulated scene of the aircraft tire 11 rolling on the pavement.
[0042] The sensor test device includes a sensor device, which includes a variety of dedicated sensors for measuring various relevant parameters of the aircraft tire 11 during the test and uploading the parameter records, wherein the sensor device is connected to the aircraft tire 11 for sensing and collecting various test data of the aircraft tire 11 during the cable passing process. On the other hand, the control device in this embodiment is mainly used to control the test process, collect test data, and complete the information exchange between the test equipment and the test personnel.
[0043] The key point is that after simulating the real scene of the tire, the test equipment of this embodiment performs the tire cable passing test through the cable passing device 20. Specifically, the cable passing device includes a variable-section steel cable 21 and a traction assembly 22. The variable-section steel cable 21 is used to contact the aircraft tire 11 to achieve cable passing, and the traction assembly 22 is used to pull the variable-section steel cable 21. During the cable passing test, the traction assembly 22 pulls the variable-section steel cable 21 from the initial position to the terminal position, and contacts and rolls with the aircraft tire 11 to complete the tire cable passing test.
[0044] In order to provide a better operating experience, a specific test process of the cable passing device is provided. Before the test, the tire posture is adjusted according to the test requirements, and the variable-section steel cable 21 is set at the preset initial position. The pavement simulation component 12 is controlled by the control device to simulate the aircraft speed and control the ground load between the aircraft tire 11 and the pavement. After reaching the predetermined test speed, the test aircraft tire 11 is pressed at the corresponding position for rolling, and then the variable-section steel cable 21 is pulled by the cable passing device 20 to pass through the aircraft tire 11 and roll to the terminal position to complete the test. During the test, a dedicated sensor is used to measure various related parameters. In multiple tests, the above process is repeated according to different tire state parameters to complete the cable passing test, and the overload, acceleration and surface damage of the tire during the cable passing process are obtained. The impact of the tire cable passing characteristics is evaluated through data analysis, and a test basis is provided for various improvements and optimization designs for improving tire quality and its characteristic parameters.
[0045] The advantage of this embodiment is that, from the perspective of tire usage conditions, a real special steel cable is used for cable passing, which not only simulates the rolling speed and impact overload of the tire, but also can measure the impact overload size of the tire under the premise of ensuring safety. In addition, the device has tire yaw and roll test functions, and then the tire performance is obtained through comprehensive analysis, and accurate tire test data is obtained, which helps to improve the quality of the tire and its cable passing performance, obtains first-hand effective data for studying tire characteristics, and provides a reliable basis for improving tire production quality and optimizing tire design.
