Description

Technical Field

[0001] The present invention relates to the technical field of performance testing of heat-proof materials, and in particular to a high-temperature performance testing system and method for heat-proof materials. Background Art

[0002] When an aircraft flies at supersonic or hypersonic speeds, high-speed gas flows through the aircraft body. Under the action of viscosity, the air is strongly compressed and rubbed against the surface of the aircraft body, causing the wall temperature to rise. The high-temperature air will continuously transfer heat to the low-temperature wall, causing strong aerodynamic heating. Aerodynamic heating will cause thermal deformation of the heat-proof material and its structure, and the strength and bearing capacity of the heat-proof material will also be significantly attenuated under the action of aerodynamic and aerodynamic heat loads.

[0003] Therefore, in order to test the attenuation performance of heat shield materials, it is necessary to test their performance in advance. However, in existing technologies, heat shield materials are generally placed in a conventional high-temperature constant temperature environment for testing. This cannot simulate the temperature changes in the product's actual operating environment, and the test data cannot truly reflect the product's performance during flight, which has certain limitations. Summary of the Invention

DETAILED DESCRIPTION

[0043] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0044] First, as Figure 1 FIG. 1 is a schematic diagram showing the connection of a high-temperature performance test system for heat-resistant materials according to an embodiment of the present invention. The system includes: a test adjustment frame 11, a variable temperature force drive composite device 12, a first control system 13, a second control system 14, and an analysis system 15;

[0045] like Figure 2 , which is a schematic diagram of the position structure of the test adjustment frame 11 and the variable temperature force drive composite equipment 12.

[0046] The test adjustment frame 11 is used to support the temperature-variable force-driven composite equipment.

[0047] Specifically, the test adjustment frame 11 includes: a support frame 111 and a movable slide 112. The support frame 111 is set beside the frame of the tensile testing machine 121 and is used to support the movable slide 112. The movable slide 112 is fixed to the support frame 111 and is used to support the temperature-changing actuator 122 in the temperature-changing force-driven composite device 12 to move horizontally back and forth relative to the heat-proof material specimen 16, thereby adjusting the relative heating position of the temperature-changing actuator 122 and the heat-proof material specimen 16. Figure 3 , is a structural diagram of the temperature-changing execution device 122 being away from the heat-proof material specimen 16.

[0048] The variable temperature force driving composite equipment 12 includes a tensile testing machine 121 and a variable temperature execution device 122. The variable temperature execution device 122 is controlled by the first control system 13 to execute a single-side thermal assessment test, and the tensile testing machine 121 is controlled by the second control system 14 to execute a mechanical tensile test.

[0049] The tensile testing machine 121 includes a frame, a transmission assembly and a fixture 1211 .

[0050] The frame is used to support the clamp 1211.

[0051] The clamp 1211 is used to clamp the exothermic material specimen. The clamp 1211 includes an upper clamping end and a lower clamping end; the lower clamping end is fixed to the frame, and the upper clamping end is connected to the transmission assembly. The heat-resistant material specimen 16 is clamped between the upper clamping end and the lower clamping end, and the windward side of the heat-resistant material specimen faces the temperature-changing actuator 122. The thickness of the heat-resistant material specimen 16 is less than 40 mm. Figure 4 , is a schematic diagram of a heat-shielding material specimen 16, which illustrates the dimensional parameters of the heat-shielding material specimen 16 in millimeters (mm). The heat-shielding material specimen 16 is exemplified as a homogeneous material, a gradient material, or a braid, but is not intended to be limiting.

[0052] The transmission assembly is used to apply an axial tensile load to the heat-resistant material specimen 16. Specifically, the transmission assembly is controlled by the second control system 14 to control the axial movement of the upper clamping end to apply an axial tensile load to the heat-resistant material specimen 16.

[0053] The temperature-variable execution device 122 includes: a temperature-variable heat source component 1221 and a trough-type heat collector 1222 .

[0054] The trough heat collector 1222 is used to accommodate the variable temperature heat source component 1221. The variable temperature heat source component 1221 is exemplified by a quartz lamp, but is not limited thereto.

[0055] In order to prevent heat from being transferred to the leeward side of the heat-proof material specimen 16, an opening is provided at the bottom of the trough of the trough-shaped collector to fit the heat-proof material specimen 16, so that the variable temperature heat source assembly 1221 is only opposite to the windward side of the heat-proof material specimen 16.

[0056] See Figure 5 , is a cross-sectional view of the variable temperature actuator 122 and the heat-shielding material specimen 16. After the heat-shielding material specimen 16 is clamped in the tensile testing machine 121, one side of the heat-shielding material specimen 16 is embedded in the bottom opening of the trough-shaped collector. This side faces the variable temperature heat source assembly 1221, i.e., the windward side of the heat-shielding material specimen 16. The heat generated by the variable temperature heat source assembly 1221 acts only on the windward side of the heat-shielding material specimen 16, while heat from other directions is absorbed by the trough-shaped collector, thereby supporting single-sided thermal assessment of the heat-shielding material specimen 16.

[0057] In order to further prevent heat from being transferred to the leeward side of the heat-proof material specimen 16, the interlocking gap between the opening of the trough-shaped collector and the heat-proof material specimen 16 is sealed with insulating asbestos to prevent heat from diffusing to the leeward side of the heat-proof material specimen 16.

[0058] To further absorb heat, the trough collector 1222 contains a cooling medium, which is connected to a cooling medium storage device via a cooling pipe 1223. The cooling medium in the cooling medium storage device can be pumped into the trough collector 1222, allowing the cooling medium to flow within the trough collector 1222. This improves heat absorption efficiency and further prevents heat from spreading to the leeward side of the heat-shielding material specimen 16, thereby preventing it from affecting the test temperature on the windward side of the heat-shielding material specimen 16. This ensures the success rate of the single-sided thermal test of the heat-shielding material specimen 16. Furthermore, this prevents excessive heat from adversely affecting other equipment.

[0059] The first control system 13 is used to control the temperature change of the variable temperature heat source assembly 1221 with reference to the flight temperature curve to achieve a single-side thermal assessment test. The heat-shielding material specimen 16 is bonded with a thermocouple 17, which can be used to test the windward surface temperature of the heat-shielding material specimen 16. Figure 6A-Figure 6B , which illustrates two installation positions of the thermocouple 17, but does not constitute a limitation. The dimensions of the heat-resistant material specimen 16 are in millimeters (mm).

[0060] The second control system 14 is used to control the tensile testing machine 121 to apply an axial tensile load to the exothermic material specimen according to the set test time and the set test rate before the end of the unilateral thermal assessment test, so as to realize the mechanical tensile test, and control the mechanical tensile test and the unilateral thermal assessment test to end at the same time.

[0061] For example, the test time is set to any time within 1s to 30s, such as 15s. The test rate is set to 5mm / min. 15s before the end of the unilateral thermal assessment test, the second control system 14 controls the tensile testing machine 121 to apply an axial tensile load to the exothermic material specimen at a set test rate of 5mm / min until the unilateral thermal assessment test stops applying the axial tensile load, thereby ensuring that the mechanical tensile test and the unilateral thermal assessment test are completed at the same time.

[0062] The analysis system 15 is used to analyze the attenuation change law of the performance of the exothermic material specimen under the action of unilateral radiation heat flux and force load with temperature and heating time based on the performance change parameters of the exothermic material specimen in the test.

[0063] The analysis system 15 is built into the computer control device. Optionally, the computer control device interacts with the first control system 13 and the second control system 14 to control the progress of the mechanical tensile test and the unilateral thermal assessment test. After the mechanical tensile test and the unilateral thermal assessment test are completed, the analysis system 15 receives the collected performance change parameters and analyzes the performance attenuation of the exothermic material specimen under the unilateral radiant heat flux and force load as a function of temperature and heating time based on the performance change parameters.

[0064] The above is an introduction to the high-temperature performance test system for heat-resistant materials in the technical solution of the present invention. In the present invention, a variable temperature force-driven composite device is established to realize the coupling effect of dynamic heat flow and force load on the heat-resistant material specimen, a variable temperature execution device is designed to ensure the unilateral thermal assessment of the heat-resistant material specimen, and a first control system is used to control the temperature change of the variable temperature heat source component with reference to the flight temperature curve to simulate the temperature change of the actual working environment of the product, and a second control system is used to control the tensile testing machine to apply an axial tensile load to the exothermic material specimen according to the set test time and set test rate before the end of the unilateral thermal assessment test, simulating the load change of the actual working environment of the product, thereby accurately testing the attenuation law of the performance of the heat-resistant material specimen under the action of unilateral radiation heat flow and load with temperature and heating time, thereby improving the material performance analysis capability.

[0065] In a second aspect, based on the same inventive concept as the high-temperature performance test system for heat-shielding materials provided in the first embodiment, an embodiment of the present invention further provides a high-temperature performance test method for heat-shielding materials. This method is applied to the high-temperature performance test system for heat-shielding materials described in the first aspect.

[0066] See Figure 7 , the method comprises the following steps:

[0067] S701, processing heat-resistant material specimens.

[0068] Specifically, first inspect the surface of the heat-resistant material test plate after surface curing. Visually inspect the surface condition of the heat-resistant material test plate, ensuring that there are no defects such as cracks and deformation. The cured heat-resistant material test plate is processed into heat-resistant material test pieces and inspected. The heat-resistant material test piece must be free of obvious defects such as wrinkles and resin accumulation.

[0069] S702, clamping the heat-resistant material specimen in a variable temperature force-driven composite device in a heat-resistant material high-temperature performance test system.

[0070] Specifically, a high temperature resistant adhesive is used to bond the thermocouple in the heat-resistant material specimen.

[0071] The heat-proof material specimen is installed in the variable temperature force drive composite equipment, and the center line of the heat-proof material specimen is consistent with the center lines of the upper clamping end and the lower clamping end.

[0072] In order to prevent the heat-resistant material specimen from slipping during the tensile test, the clamping end of the heat-resistant material specimen is sandblasted.

[0073] Furthermore, to conduct a single-sided thermal assessment of the heat-shielding material specimen and prevent heat transfer to the leeward side of the specimen, the specimen was insulated. Specifically, a trough-shaped collector was installed parallel to the specimen to absorb heat. The trough-shaped collector accommodated a variable-temperature heat source assembly. Insulating asbestos was used to seal the gap between the opening of the trough-shaped collector and the heat-shielding material specimen to prevent heat from diffusing to the leeward side of the specimen, thereby affecting the test temperature of the windward side of the specimen.

[0074] S703 , controlling the temperature change of the variable temperature heat source assembly by referring to the flight temperature curve through the first control system to implement a single-side thermal assessment test.

[0075] Specifically, the flight temperature profile file is input into the first control system. The first control system analyzes the flight temperature profile file to obtain a flight temperature curve, controls the temperature change of the variable temperature heat source assembly based on the flight temperature curve, and implements PID temperature control of the variable temperature heat source assembly to achieve a single-side thermal assessment test.

[0076] Furthermore, during single-sided thermal testing, the cooling medium flow within the trough collector is controlled to prevent heat from spreading to the leeward side of the thermal barrier material specimen, thereby preventing it from affecting the test temperature on the windward side. This ensures the success rate of single-sided thermal testing of the thermal barrier material specimen. Furthermore, it prevents excessive heat from adversely affecting other equipment.

[0077] S704, before the end of the unilateral thermal assessment test, the second control system controls the tensile testing machine to apply an axial tensile load to the exothermic material specimen according to the set test time and the set test rate to realize the mechanical tensile test, and controls the mechanical tensile test and the unilateral thermal assessment test to end at the same time.

[0078] For example, 15 seconds before the end of the unilateral thermal assessment test, the second control system controls the tensile testing machine to apply an axial tensile load to the exothermic material specimen at a set test rate of 5 mm / min until the unilateral thermal assessment test stops and the axial tensile load is stopped, thereby ensuring that the mechanical tensile test and the unilateral thermal assessment test are completed at the same time.

[0079] S705, analyzing the performance variation of the exothermic material specimen under the action of unilateral radiation heat flux and force load with temperature and heating time based on the performance variation parameters of the exothermic material specimen during the test through the analysis system.

[0080] Specifically, this embodiment mainly analyzes the variation patterns of the strength, modulus, and elongation of the exothermic material specimen under the action of unilateral radiation heat flux and force load with temperature and heating time based on the performance change parameters generated in the mechanical tensile test and the unilateral thermal assessment test.

[0081] Taking strength as an example, the strength of the exothermic material specimen in the test will change with the increase of force load. By collecting strength-related performance change parameters, such as tension, combined with the parameters of the exothermic material specimen itself (such as specimen size) and test-related parameters, the strength of the exothermic material specimen under unilateral radiation heat flux and force load can be analyzed as a function of temperature and heating time.

[0082] The above method can realize the performance testing of heat-proof materials of different thicknesses, and test the variation patterns of strength, modulus, and elongation of heat-proof materials of different thicknesses under unilateral radiation heat flux and static load with temperature and heating time, which can improve the material performance analysis capability.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0084] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
