Description

Technical Field

[0001] The present disclosure relates to the technical field of stiffened wall panel testing, and in particular to an in-plane loading testing device for stiffened wall panels. Background Art

[0002] Composite material reinforced panels are widely used in engineering structures such as aerospace and rail transportation, especially in the design of key equipment such as aircraft, satellites, and rockets. Composite materials can effectively improve structural performance and reduce weight under complex load conditions due to their high specific strength, specific stiffness, and good corrosion resistance, making them an ideal choice for high-performance and lightweight design. With the development of technology, the application scope of composite materials has been continuously expanded, gradually developing from the initial non-load-bearing and secondary load-bearing components to the main load-bearing components, and evolving towards large-scale and integrated directions. As a common load-bearing structural component, composite material reinforced panels are widely used in main load-bearing components such as aircraft fuselages, wings, vertical tails, horizontal tails, and rocket launcher sections. The integrated forming process includes prepreg-autoclave forming process, RTM (resin transfer molding) or RFI (resin film infiltration) forming process, etc.

[0003] In the related technology, composite stiffened panels are widely used as load-bearing structural parts in key parts such as aircraft wings, tails and fuselages. These stiffened panels can not only withstand large in-plane loads, but also significantly improve local load-bearing capacity through reinforcement design, avoiding failure modes that are prone to occur in single-plate structures. Under the action of buckling loads, composite stiffened panels can still maintain a strong post-buckling load-bearing capacity and have obvious performance advantages. However, the current aircraft design is still mainly based on traditional buckling loads as design loads, which fails to give full play to the post-buckling load-bearing capacity of composite stiffened panels and the ultimate load-bearing performance of the overall structure.

[0004] Traditionally, the test chamber for reinforced wall panels needs to use box-section test pieces to apply bending, torsion and other loads to verify the structural performance of the reinforced wall panels. This method of verifying the structural performance of reinforced wall panels mainly relies on complex test equipment and has high experimental costs. At the same time, this test method usually simulates and verifies the bending, torsion and other loads of the reinforced wall panels, lacking systematic testing and analysis of the in-plane loads of the reinforced wall panels.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0031] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0032] In related technologies, composite reinforced panels are widely used in engineering structures such as aerospace and rail transit, and they play an important role in the design of key equipment such as aircraft, satellites, and rockets. Before the reinforced panels are used, they need to be tested to determine their relevant performance. In some tests, the structural performance of the reinforced panels is verified mainly by applying bending, torsion and other loads through box-section test pieces. This method of verifying the structural performance of reinforced panels mainly relies on complex test equipment and has high experimental costs. At the same time, in this test method, the bending, torsion and other loads of the reinforced panels are usually simulated and verified. The lack of systematic testing and analysis of the in-plane loads of the reinforced panels leads to inaccurate measurement of the in-plane loads of the reinforced panels.

[0033] Based on this, see Figure 1 , Figure 4The embodiment of the present disclosure provides an in-plane loading test device for a reinforced wall panel. The reinforced wall panel 7 includes a straight plate 71 and a vertical plate 72; the straight plate 71 is connected to the vertical plate 72, and the length direction of the straight plate 71 is perpendicular to the length direction of the vertical plate 72; the test device includes a first plate 1, a second plate 2, a control mechanism 3, a driving mechanism 4, a fixing mechanism 5 and a clamping mechanism 6; the first plate 1 is connected to the second plate 2, and a test space for the reinforced wall panel 7 is formed between the first plate 1 and the second plate 2; the fixing mechanism 5 is arranged in the test space, and is used to fix the straight plate 71 in the test space; the clamping mechanism 6 is connected to the vertical plate 72, and is used to clamp the vertical plate 72; the driving mechanism 4 is connected to the fixing mechanism 5, and is used to apply a load to the reinforced wall panel 7 via the fixing mechanism 5; the control mechanism 3 is connected to the driving mechanism 4, and the control mechanism 3 is used to control the load applied by the driving mechanism 4.

[0034] In the embodiment of the present disclosure, when the in-plane load of the reinforced wall panel 7 is tested, the driving mechanism 4 is turned on, the driving mechanism 4 drives the fixing mechanism 5 to move, and the movement of the fixing mechanism 5 makes the test space larger, and then the reinforced wall panel 7 is placed in the test space, the fixing mechanism 5 is adjusted, the fixing mechanism 5 fixes the flat plate 71, the clamping mechanism 6 is adjusted, the clamping mechanism 6 is close to the vertical plate 72, and the clamping mechanism 6 clamps the vertical plate 72, the driving mechanism 4 is turned on, the driving mechanism 4 drives the fixing mechanism 5 to move, and the cooperation between the fixing mechanism 5 and the clamping mechanism 6 drives the reinforced wall panel 7 to change, and at the same time, when the in-plane load of the reinforced wall panel 7 is tested, the output power of the driving mechanism 4 can be controlled by the control mechanism 3. In this way, the in-plane load of the reinforced wall panel 7 can be measured by the testing machine connected to the test device.

[0035] In some embodiments of the present disclosure, see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The fixing mechanism 5 includes a first clamping assembly 51 and a second clamping assembly 52; the first clamping assembly 51 includes a first double-ear support 511, at least two first transition plates 512, a first fixing piece 513 and a second fixing piece 514; one side of the first double-ear support 511 is connected to the first plate 1 through the driving mechanism 4; one side of the two first transition plates 512 is connected to the other side of the first double-ear support 511 through the first fixing piece 513, and the other side of the two first transition plates 512 has a fixing space for fixing one end of the straight plate 71; the second fixing piece 514 is used to fix one end of the straight plate 71 to the two first transition plates 512; the second clamping assembly 52 is arranged on the second plate 2, and is used to fix the other end of the straight plate 71.

[0036] Specifically, when it is necessary to fix the straight plate 71 by the fixing mechanism 5, one end of the straight plate 71 is extended into the fixing space formed by the first transition plate 512, and the second fixing member 514 is used to fix the straight plate 71 to the first transition plate 512, and then the other end of the straight plate 71 is fixed to the second clamping assembly 52, so that the purpose of fixing the straight plate 71 by the fixing mechanism 5 is achieved.

[0037] As an example, the first fixing member 513 may include a first bolt 5131 and a first nut 5132; the first double-ear support 511 has a first mounting groove (this is not specifically marked in the drawings of the present application). When the two first transition plates 512 are connected to the first double-ear support 511, the first transition plate 512 is extended into the first mounting groove, and the first bolt 5131 is used to pass through the first double-ear support 511 and the first transition plate 512. The first nut 5132 is installed on the part where the first bolt 5131 passes through the first double-ear support 511, and the first nut 5132 is turned to fix the first double-ear support 511 to the first transition plate 512.

[0038] Furthermore, the second fixing member 514 may include a second bolt 5141 and a second nut 5142; when it is necessary to fix one end of the straight plate 71 to the first transition plate 512, first extend one end of the straight plate 71 into the fixing space formed by the first transition plate 512, then pass the second bolt 5141 through the first transition plate 512 and the straight plate 71, and then install the second nut 5142 on the part where the second bolt 5141 passes through the first transition plate 512, and turn the second nut 5142 to fix the first transition plate 512 to the straight plate 71.

[0039] It should be noted that, since the first double-ear support 511 has a first pointed cone portion 5111 on the side away from the first plate 1, if the first pointed cone portion 5111 is connected and fixed to one side of the straight plate 71, on the one hand, the fixing effect on one side of the straight plate 71 is poor, affecting the accuracy of the in-plane load test of the stiffened wall plate 7; on the other hand, it will cause uneven force on one side of the straight plate 71, further affecting the accuracy of the in-plane load test of the stiffened wall plate 7. Based on this, in the embodiment of the present disclosure, this problem can be solved by setting a first transition plate 512.

[0040] Specifically, the first transition plate 512 has a second conical portion 5121 on one side close to the first double-ear support 511 . When the first double-ear support 511 and the first transition plate 512 need to be fixed, the first fixing member 513 is used to fix the first conical portion 5111 and the second conical portion 5121 .

[0041] In some embodiments of the present disclosure, the second clamping assembly 52 includes a second double-ear support 521, at least two second transition plates 522, a third fixing member 523 and a fourth fixing member 524; the second double-ear support 521 is arranged on the second plate 2; one end of the two second transition plates 522 is connected to the second double-ear support 521 through the third fixing member 523, and the other end of the two second transition plates 522 has a fixing space for fixing the other end of the straight plate 71, and the other end of the straight plate 71 is fixedly connected to the second transition plate 522 through the fourth fixing member 524.

[0042] Specifically, when it is necessary to fix the other end of the straight plate 71 (at this time, one end of the second transition plate 522 has been fixed to the second double-ear support 521 through the third fixing member 523), the other end of the straight plate 71 is extended into the fixed space formed by the two second transition plates 522. When the other end of the straight plate 71 is extended into the fixed space formed by the two second transition plates 522, the fourth fixing member 524 is used to fix the other end of the straight plate 71 to the second transition plate 522.

[0043] It should be noted that, since the second double-ear support 521 has a third pointed cone portion 5211 on the side away from the second plate 2, if the third pointed cone portion 5211 is connected and fixed to one side of the straight plate 71, on the one hand, it will lead to poor fixing effect on one side of the straight plate 71, affecting the accuracy of the in-plane load test of the stiffened wall panel 7, and on the other hand, it will cause uneven force on one side of the straight plate 71, further affecting the accuracy of the in-plane load test of the stiffened wall panel 7. Based on this, in the embodiment of the present disclosure, this problem can be solved by setting a second transition plate 522.

[0044] Specifically, the second transition plate 522 has a fourth conical portion 5221 on one side close to the second double-ear support 521 . When the second double-ear support 521 and the first transition plate 512 need to be fixed, the third conical portion 5211 and the fourth conical portion 5221 are fixed using the third fixing member 523 .

[0045] As an example, the third fixing member 523 may include a third bolt 5231 and a third nut 5232; the second double-ear support 521 has a second mounting groove (this is not specifically marked in the drawings of the present application). When the two second transition plates 522 are connected to the second double-ear support 521, the second transition plate 522 is extended into the second mounting groove, and the third bolt 5231 is used to pass through the second double-ear support 521 and the second transition plate 522. The first nut 5132 is installed on the part of the first bolt 5131 that passes through the first double-ear support 511, and the first nut 5132 is turned to fix the second double-ear support 521 to the second transition plate 522.

[0046] Furthermore, the fourth fixing member 524 may include a fourth bolt 5241 and a fourth nut 5242; when it is necessary to fix the other end of the straight plate 71 to the second transition plate 522, first extend the straight plate 71 into the fixed space formed by the second transition plate 522, then pass the fourth bolt 5241 through the second transition plate 522 and the straight plate 71, and then install the fourth nut 5242 on the part where the fourth bolt 5241 passes through the second transition plate 522, and turn the fourth nut 5242 to fix the second transition plate 522 to the straight plate 71.

[0047] In some embodiments of the present disclosure, a plurality of second fixing members 514 and a plurality of fourth fixing members 524 are provided along the width direction of the flat plate 71, and the plurality of second fixing members 514 and the plurality of fourth fixing members 524 are evenly distributed. In this way, by providing a plurality of second fixing members 514 along the width direction of the flat plate 71, the connection strength between one end of the flat plate 71 and the first transition plate 512 can be improved, and the stability of the test can be ensured; by providing a plurality of fourth fixing members 524 along the width direction of the flat plate 71, the connection strength between the other end of the flat plate 71 and the second transition plate 522 can be improved, and the stability of the test can be further ensured, thereby improving the measurement accuracy of the test to a certain extent.

[0048] In the application drawings, the number of the second fixing members 514 and the fourth fixing members 524 arranged along the width direction of the straight plate 71 is five. It should be noted that in the remaining embodiments of the present disclosure, the number of the second fixing members 514 and the fourth fixing members 524 is not limited to this, and this application will not elaborate on it.

[0049] In some embodiments of the present disclosure, the second fixing member 514 disposed on the first transition plate 512 is disposed in a one-to-one correspondence with the fourth fixing member 524 disposed on the second transition plate 522 .

[0050] It can be understood that in the embodiment of the present disclosure, along the length direction of the flat plate 71, the second fixing member 514 provided on the first transition plate 512 and the fourth fixing member 524 provided on the second transition plate 522 are located on the same horizontal line. In this way, when the driving mechanism 4 applies a load to the stiffened wall panel 7 through the fixing mechanism 5, the load applied to the stiffened wall panel 7 can be relatively uniform, thereby effectively improving the accuracy of the test on the stiffened wall panel 7.

[0051] In some embodiments of the present disclosure, see Figure 1 , Figure 4The clamping mechanism 6 includes a clamping bracket 61, a clamping plate 62, a slider 63, a fifth fixing member 64 and a sixth fixing member 65; the clamping bracket 61 can be movably connected to the second plate 2, and the movement direction of the clamping bracket 61 is perpendicular to the plane where the straight plate 71 is located; the fifth fixing member 64 is used to fix the clamping bracket 61 to the second plate 2; the clamping plate 62 is movably connected to the clamping bracket 61 through the slider 63, and the movement direction of the slider 63 is the same as the length direction of the straight plate 71; the side of the clamping plate 62 away from the slider 63 has a clamping groove 622 for clamping the vertical plate 72; the sixth fixing member 65 is used to fix the vertical plate 72 to the clamping plate 62.

[0052] Specifically, when the vertical plate 72 needs to be clamped, the clamping bracket 61 is moved, and the clamping bracket 61 drives the slider 63 and the clamping plate 62 to approach the vertical plate 72. When the vertical plate 72 extends into the clamping groove 622, the sixth fixing member 65 is used to fix the vertical plate 72 and the clamping plate 62, and the fifth fixing member 64 is used to fix the clamping bracket 61 and the second plate 2.

[0053] Furthermore, when clamping reinforced wall panels 7 of different specifications (for example, the positions of the vertical plates 72 of reinforced wall panels 7 of different specifications on the straight plates 71 are different), when the clamping plate 62 is close to the vertical plate 72, the relative position of the slider 63 on the clamping bracket 61 is adjusted, and the movement of the slider 63 drives the clamping plate 62 to move in the vertical direction on the clamping bracket 61. When the clamping plate 62 and the vertical plate 72 are located in the same horizontal plane, the clamping bracket 61 is adjusted to be close to the vertical plate 72. When the vertical plate 72 extends into the clamping groove 622, the sixth fixing member 65 is used to fix the vertical plate 72 and the clamping plate 62, and the fifth fixing member 64 is used to fix the clamping bracket 61 and the second plate 2.

[0054] In summary, in the embodiment of the present disclosure, by movably setting the clamping bracket 61 on the second plate 2, and by movably setting the slider 63 on the clamping bracket 61, clamping of reinforced wall panels 7 of different specifications can be achieved, so that reinforced wall panels 7 of different specifications can be tested, thereby improving the scope of application of the device.

[0055] As an example, eight adjustment holes 611 are symmetrically arranged at the bottom of the clamping bracket 61, so as to meet the measurement requirements of reinforced wall panels 7 of different specifications. It should be noted that in other embodiments of the present disclosure, the number of adjustment holes 611 is not limited to this, and this application will not elaborate.

[0056] Furthermore, the fifth fixing member 64 may include a fifth bolt 641; specifically, when the clamping bracket 61 moves to a suitable position on the second plate 2, the fifth fixing bolt 66 is installed in the adjustment hole 611, and the fifth fixing bolt 66 is rotated to achieve the purpose of fixing the clamping bracket 61 to the second plate 2.

[0057] The sixth fixing member 65 may include a sixth bolt 651 and a sixth nut 652; specifically, when the vertical plate 72 extends into the clamping groove 622, the sixth bolt 651 is used to pass through the clamping plate 62 and the vertical plate 72, the fifth bolt 641 is installed on the part where the sixth bolt 651 passes through the clamping plate 62, and the knob fifth nut is used to achieve the purpose of fixing the vertical plate 72 to the clamping plate 62.

[0058] In some embodiments, a damping portion may be provided on one side of the clamping bracket 61 close to the second plate 2 (this is not specifically marked in the drawings of the present application). The provided damping portion may increase the friction between the clamping bracket 61 and the second plate 2 to prevent the clamping bracket 61 from being displaced when the reinforced wall panel 7 is tested, thereby preventing the reinforced wall panel 7 from moving.

[0059] In some embodiments, the damping part can be obtained by roughening the bottom of the clamping bracket 61. For example, a specific texture can be machined by a milling machine or polished by external equipment, etc., which is not limited in the embodiments of the present disclosure.

[0060] In some embodiments of the present disclosure, see Figure 4 The clamping plate 62 has an enlarged portion 621 on one side close to the slider 63. In this way, when the reinforced wall panel 7 is tested, the enlarged portion 621 can increase the connection strength between the clamping plate 62 and the slider 63, improve the stability of the device, and ensure the accuracy of the test of the reinforced wall panel 7.

[0061] In some embodiments of the present disclosure, the clamping mechanism 6 further includes a plurality of fixing bolts 66; along the vertical direction of the clamping bracket 61, the clamping bracket 61 is provided with a plurality of fixing holes 612, and the plurality of fixing bolts 66 sequentially pass through the corresponding enlarged portion 621 and the slider 63 and extend into the fixing hole 612 to be threadedly connected with the clamping bracket 61. Specifically, when it is necessary to adjust the relative position of the clamping plate 62 on the clamping bracket 61 to meet the testing requirements of the reinforced wall panels 7 of different specifications, the position of the slider 63 on the clamping bracket 61 is adjusted, and when the slider 63 reaches the appropriate position, the fixing bolts 66 are sequentially passed through the corresponding enlarged portion 621 and the slider 63, the fixing bolts 66 are extended into the fixing hole 612, the knob is turned to fix the bolts 66, and the fixing bolts 66 are threadedly connected with the clamping bracket 61 to achieve the purpose of adjusting the clamping plate 62 to the appropriate position.

[0062] It should be noted that in the embodiment of the present disclosure, there is no specific limitation on the number of fixing holes 612 and fixing bolts 66 .

[0063] In some embodiments of the present disclosure, see Figure 6 , Figure 7 The driving mechanism 4 includes a driving cylinder 41; the base of the driving cylinder 41 is connected to the first plate 1, the piston rod of the driving cylinder 41 is connected to the first double-ear support 511, and the movement direction of the driving cylinder 41 is the same as the length direction of the flat plate 71. When the reinforced wall panel 7 needs to be tested, the driving cylinder 41 is turned on, and the driving cylinder 41 extends or contracts, which can move the first double-ear support 511 and the first transition plate 512, so as to achieve the purpose of applying load to the reinforced wall panel 7.

[0064] In some embodiments of the present disclosure, the driving mechanism 4 also includes a guide column 42; the guide column 42 is arranged on the side of the first double-ear support 511 close to the first plate 1, and the guide column 42 has a limiting hole 421, wherein the depth direction of the limiting hole 421 is the same as the movement direction of the driving cylinder 41, and the piston rod of the driving cylinder 41 can extend into the limiting hole 421.

[0065] Specifically, when a load is applied to the reinforced wall panel 7, the driving cylinder 41 moves, and the piston rod of the driving cylinder 41 extends into the limiting hole 421. The side wall of the limiting hole 421 can limit the driving cylinder 41 to prevent the piston rod from being offset relative to the reinforced wall panel 7 when the driving cylinder 41 moves up and down, thereby improving the accuracy of the test of the reinforced wall panel 7.

[0066] In some embodiments of the present disclosure, the control mechanism 3 may be a force sensor, and the force sensor is connected to the driving cylinder 41 , so that the purpose of accurately controlling the load applied by the driving cylinder 41 can be achieved through a testing machine.
