Description

Technical Field

[0001] This invention relates to the field of composite reinforced wall panel profile adjustment technology, specifically to an automatic profile adjustment device and method for composite reinforced wall panels. Background Technology

[0002] Composite stiffened panel structures have been widely used in helicopter and aircraft structures due to their advantages of good overall formability, high load-bearing efficiency, and fewer connectors. The skin and stringers of composite stiffened panels can be connected through co-curing and co-bonding, significantly reducing the number of connectors, assembly workload, stress concentration, and the weakening of the panel cross-section by rivet holes, while also reducing the weight of the connectors themselves.

[0003] Because the surface of the composite reinforced wall panel undergoes certain deformation during the actual production process, there will be a difference between the actual production surface and the design surface. Therefore, after the composite reinforced wall panel is produced, it is usually necessary to conduct relevant tests on its overall surface and apply loads to the deformed parts of the surface to adjust the amount of deformation in order to meet the requirements for safe use.

[0004] Existing methods for profile adjustment mainly involve manual adjustment, which means manually applying a certain load to the deformed profile using a simple pressure device (such as a push-pull force gauge), or directly placing a fixed weight (such as a sandbag) on ​​the deformed profile. Both of these methods have the following drawbacks:

[0005] 1. It is impossible to accurately calculate the applied load value, requiring multiple attempts to adjust the load value, resulting in high labor intensity;

[0006] 2. When using manual adjustment of the profile, if multiple positions of the same profile need to be adjusted, it will not only consume a lot of human resources, but also reduce the accuracy of the adjustment amount of each deformation position due to the mutual influence between the adjustment positions. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an automatic adjustment device for the profile of reinforced composite material wall panels, so as to solve the technical problem that the profile deformation of existing reinforced composite material wall panels is not easy to adjust.

[0008] The technical solution adopted in this invention is: an automatic adjustment device for the profile of a composite material reinforced wall panel, comprising:

[0009] A support base, which can be simply supported on all four sides of a composite material reinforced wall panel;

[0010] A positioning beam is horizontally positioned above the support base and is fixedly connected to the support base;

[0011] A positioning frame, wherein multiple positioning frames are arranged at equal intervals in the transverse direction and are fixedly connected to the positioning beam;

[0012] A loading column, which is connected to a positioning frame and can be raised and lowered;

[0013] A sensor, which is installed at the bottom end of the loading column, is used to detect the loading force exerted by the loading column on the composite material reinforced wall panel;

[0014] The controller is electrically connected to the loading column and the sensor, and is capable of controlling the lifting and lowering of the loading column and acquiring the loading force.

[0015] Preferably, there is one positioning beam, and the longitudinal position of the positioning beam on the support base is adjustable.

[0016] Preferably, the plurality of positioning beams are arranged at equal intervals along the longitudinal direction, and the longitudinal distance between two adjacent positioning beams can be adjusted.

[0017] Preferably, the positioning beam includes a transverse beam and a column, the top end of the column is vertically fixedly connected to the end of the transverse beam, and the bottom end is movably fixedly connected to the support base.

[0018] Preferably, multiple longitudinal positioning holes are linearly and evenly distributed on both sides of the support base in the width direction, and the support base is provided with longitudinal fastening bolts, which pass through the longitudinal positioning holes and are fixedly connected to the bottom end of the column.

[0019] Preferably, the longitudinal distance between two adjacent longitudinal positioning holes is greater than or equal to 300 mm.

[0020] Preferably, the positioning frame and the positioning beam are movably and fixedly connected so that the lateral distance between two adjacent positioning frames can be adjusted.

[0021] Preferably, the positioning beam has a plurality of transverse positioning screw holes linearly and evenly distributed along the transverse direction on its transverse beam, and the positioning frame includes a connecting part and a transverse fastening bolt, wherein the transverse fastening bolt passes through the connecting part and is threaded into the transverse positioning screw hole.

[0022] Preferably, the positioning frame is provided with a vertical guide hole, the loading column includes a lifting column and a push-pull motor, the lifting column is slidably connected in the guide hole, the push-pull motor is fixedly connected to the positioning frame, and the push-pull end of the push-pull motor is connected to the lifting column for driving the lifting column to rise and fall.

[0023] Another object of the present invention is to provide an automatic adjustment method for the profile of a composite material reinforced wall panel, the method comprising the following steps:

[0024] S10: Obtain the deformation position of the composite material stiffened wall panel, and determine the loading position and deformation amount of the four-sided simply supported composite material stiffened wall panel based on the deformation position;

[0025] S20: First, calculate the elastic coefficient using the Navierian solution formula for simply supported rectangular thin plates. Then, substitute the elastic coefficient and deformation into the Hooke's Law formula to calculate the theoretical loading force at each loading position.

[0026] The Navierian solution formula is as follows: Hooke's Law is formulated as follows:

[0027] S30: Compare the theoretical loading force with the loading force threshold. If the theoretical loading force is less than the loading force threshold, then execute S40. If the theoretical loading force is greater than or equal to the loading force threshold, then increase the number of loading positions and recalculate the theoretical loading force until the theoretical loading force is less than the loading force threshold.

[0028] S40: Simultaneously apply an adjustment loading force to the loading position until the adjustment loading force is equal to the theoretical loading force.

[0029] The beneficial effects of this invention are:

[0030] This invention utilizes Navier's solution and Hooke's law for simply supported rectangular thin plates to calculate the theoretical loading force at each deformation position on the profile of a composite reinforced panel. Then, loading columns with a controlled matrix distribution apply the theoretical loading force to the adjustment position of the simply supported composite reinforced panel. All deformation positions can be adjusted in a single loading operation, which not only reduces the labor intensity of profile adjustment for composite reinforced panels but also improves the accuracy and precision of profile adjustment, thereby increasing the production efficiency of composite reinforced panels.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0051] Examples, such as Figures 1-4 As shown, an automatic profile adjustment device for reinforced composite material wall panels includes:

[0052] The support base 100 is simply supported on all four sides of the composite material reinforced wall panel 700 and is used to provide simply supported support on all four sides of the composite material reinforced wall panel 700.

[0053] A positioning beam 200 is provided above the support base 100 in the transverse direction, and both ends of the positioning beam 200 are fixedly connected to the support base 100 in the transverse direction.

[0054] Positioning brackets 300, there are multiple positioning brackets 300, and the multiple positioning brackets 300 are equally spaced in the transverse direction and fixedly connected to one side of the positioning beam 200.

[0055] There are multiple loading columns 400, and each loading column 400 is connected to a positioning frame 300 in a one-to-one correspondence and can be raised and lowered.

[0056] Multiple sensors 500 are provided, and each sensor 500 is installed at the bottom of the loading column 400 to detect the loading force exerted by the loading column 400 on the composite material reinforced wall panel 700 in the vertical direction.

[0057] The controller 600 is electrically connected to the loading column 400 and the sensor 500 respectively, and the controller 600 can control the lifting and lowering of the loading column 400 and acquire the loading force detected by the sensor 500.

[0058] This application first connects a composite reinforced wall panel 700 to a support base 100 with four simply supported sides. Using Navier's solution and Hooke's law for simply supported rectangular thin plates, the theoretical loading force at each deformation position on the surface of the composite reinforced wall panel 700 is calculated, achieving accurate calculation of the loading force for adjusting the surface of the composite reinforced wall panel 700. Then, a positioning beam 200 is fixedly connected horizontally above the support base 100, and multiple positioning frames 300 are fixed at equal intervals on the positioning beam 200. Simultaneously, loading columns 400 are vertically and vertically connected to the positioning frames 300, achieving a matrix distribution of the loading columns 400 above the composite reinforced wall panel 700. Finally, by controlling all the loading columns 400 to synchronously apply the theoretical loading force to the adjustment position of the composite reinforced wall panel 700, a single loading operation can achieve surface adjustment at all deformation positions. This not only reduces the labor intensity of surface adjustment but also improves the accuracy and precision of surface adjustment, thereby increasing the production efficiency of the composite reinforced wall panel 700.

[0059] It should be noted that the vertical direction in this application refers to... Figure 2The double arrows in the image indicate the direction, with the horizontal direction referring to... Figure 2 The direction of the single arrow in the image.

[0060] The simple support connection between the support base 100 and the composite material reinforced wall panel 700 is existing technology and will not be described in detail here.

[0061] In one specific embodiment, such as Figure 1 As shown, there is one positioning beam 200, and the longitudinal position of the positioning beam 200 on the support base 100 is adjustable.

[0062] This design is based on the following: By placing a positioning beam 200 above the support base 100 along the lateral direction, the deformation of the composite reinforced wall panel 700 can be adjusted in the lateral direction; in conjunction with the adjustment of the longitudinal position of the positioning beam 200 on the support base 100, the positioning beam 200 can be moved to any position of the composite reinforced wall panel 700 in the longitudinal direction, thereby realizing the adjustment of any position of the composite reinforced wall panel 700; at the same time, since the number of positioning beams 200 and positioning frames 300 is small, the overall structure of the device is simple and easy to control.

[0063] In one specific embodiment, such as Figure 2 As shown, there are multiple positioning beams 200, and the multiple positioning beams 200 are arranged at equal intervals along the longitudinal direction, and the longitudinal spacing between two adjacent positioning beams 200 can be adjusted.

[0064] This setup is because, in actual production activities, the deformation location and quantity of the composite material stiffened wall panel 700 profile are random. However, the theoretical loading force calculated by the Navierian solution and Hooke's law for a simply supported rectangular thin plate is distributed in a matrix. Therefore, a sufficient number of loading columns 400 are needed to simultaneously complete the adjustment of all deformation locations. In other words, the loading columns 400 need to be distributed in a matrix so that the loading locations cover the matrix points where the theoretical loading force is located.

[0065] In this embodiment, multiple positioning beams 200 are evenly spaced along the longitudinal direction, and multiple positioning frames 300 are evenly spaced along the transverse direction on the positioning beams 200, so that all loading columns 400 are arranged in a matrix, allowing all deformation positions to be adjusted simultaneously with a single loading operation. Furthermore, the position of the loading column 400 can be adjusted by changing the longitudinal spacing between two adjacent positioning beams 200, ensuring that the loading column 400 is positioned above the deformation position (i.e., the loading position).

[0066] In one specific embodiment, such as Figure 2 , Figure 3As shown, the positioning beam 200 includes a transverse beam 210 and two columns 220. The two columns 220 are arranged one-to-one at both ends of the transverse beam 210, and the top of the column 220 is vertically fixedly connected to the end of the transverse beam 210, so that the positioning beam 200 is Π-shaped as a whole. The bottom of the column 220 is movably fixedly connected to the support base 100 so that the longitudinal position of the positioning beam 200 on the support base 100 can be adjusted.

[0067] This configuration is based on the fact that, in actual production activities, the deformation location and quantity of the composite reinforced wall panel 700 are random. In this embodiment, the positioning beam 200 consists of a transverse beam 210 and a column 220, and the bottom end of the column 220 is movably and fixedly connected to the support base 100. This allows the position of the positioning beam 200 on the support base 100 in the longitudinal direction to be adjusted, thereby moving the loading column 400 on the positioning beam 200 longitudinally above the deformation location (i.e., the loading location) of the composite reinforced wall panel 700. No loading column 400 is installed above the location where no deformation occurs (i.e., the location where the theoretical loading force is zero), thus reducing the number of loading columns 400, simplifying the device structure, and reducing the production and procurement costs of the device.

[0068] Meanwhile, in this embodiment, since the positioning beam 200 can move in the longitudinal direction, the spacing between two adjacent positioning beams 200 can be adjusted. In other words, when calculating the theoretical loading force using the Navierian solution and Hooke's law for a simply supported rectangular thin plate, the spacing between the loading positions of the matrix distribution can be adjusted, that is, the distance between two adjacent matrix points can be adjusted.

[0069] In one specific embodiment, such as Figure 1 , Figure 2 As shown, the support base 100 is provided with two rows of longitudinal positioning holes 110. The longitudinal positioning holes 110 are located on both sides of the support base 100 in the width direction and are linearly distributed at equal intervals in the longitudinal direction. The support base 100 is provided with longitudinal fastening bolts 120 that cooperate with the column 220. The longitudinal fastening bolts 120 pass through the longitudinal positioning holes 110 and are fixedly connected to the bottom end of the column 220. That is, the top end of the longitudinal fastening bolts 120 is threadedly connected to the threaded hole at the bottom end of the column 220.

[0070] This design is because: longitudinal positioning holes 110 are provided at equal intervals at both ends of the support base 100 in the lateral direction, and the column 220 of the positioning beam 200 is fixedly connected to the support base 100 by longitudinal fastening bolts 120 passing through the longitudinal positioning holes 110. This not only allows for the quick fixed connection between the positioning beam 200 and the support base 100, but also allows for the quick positioning of the positioning beam 200 on the support base 100.

[0071] More preferably, the longitudinal distance between two adjacent longitudinal positioning holes 110 is greater than or equal to 300 mm.

[0072] In one specific embodiment, such as Figure 1 , Figure 2 As shown, multiple positioning frames 300 are equally spaced along the lateral direction on the same side of the positioning beam 200, and each positioning frame 300 is movably and fixedly connected to the positioning beam 200 so that the lateral distance between two adjacent positioning frames 300 can be adjusted.

[0073] This configuration is based on the following: The positioning frame 300 and the positioning beam 200 are detachably and fixedly connected, allowing the spacing between adjacent positioning frames 300 to be adjusted. This not only fixes the loading column 400 on the positioning frame 300 above the loading position but also reduces the number of positioning frames 300 and loading columns 400 installed on the positioning beam 200. Simultaneously, the lateral spacing between adjacent positioning frames 300 can be adjusted synchronously with the longitudinal spacing of adjacent positioning beams 200, thus achieving an adjustable matrix size when the loading column 400 is distributed (i.e., each loading column 400 is located at a matrix point in the same matrix, and no loading column 400 is set at matrix points where the theoretical loading force is zero).

[0074] In one specific embodiment, such as Figure 2 , Figure 4 As shown, a plurality of transverse positioning screw holes 230 are provided on the transverse beam 210 of the positioning beam 200, and the plurality of positioning screw holes are linearly distributed at equal intervals along the transverse direction; the positioning frame 300 includes a connecting part 310, a horizontal guide part 320 and a transverse fastening bolt 330, wherein the connecting part 310 is U-shaped with the opening facing downward, and the connecting part 310 is upside down on the transverse beam 210, and a through hole is provided at the top of the connecting part 310; the transverse fastening bolt 330 passes through the connecting part 310 and is threadedly connected to the transverse positioning screw hole 230, that is, the transverse fastening bolt 330 is coaxially arranged in the through hole and threadedly connected to the transverse positioning screw hole 230 on the transverse beam 210, for clamping and fixing the connecting part 310 and the transverse beam 210 of the positioning beam 200.

[0075] This design is because: equal-spaced transverse positioning screw holes 230 are provided on the transverse beam 210 along the transverse direction, and the connecting part 310 of the positioning frame 300 is placed on the transverse beam 210. With the transverse fastening bolt 330 passing through the connecting part 310 and the threaded connection of the transverse positioning screw holes 230, the positioning frame 300 and the positioning beam 200 can be fixedly connected quickly, and the positioning frame 300 can be positioned on the positioning beam 200 quickly.

[0076] Preferably, the lateral spacing between two adjacent lateral positioning screw holes 230 is greater than or equal to 300mm.

[0077] In one specific embodiment, such as Figure 1 , Figure 3 , Figure 4 As shown, the positioning frame 300 includes a connecting part 310 and a horizontal guide part 320. The connecting part 310 can be detachably and fixedly connected to the positioning beam 200. The horizontal guide part 320 is arranged in the horizontal direction and fixedly connected to one side of the connecting part 310. A vertical guide hole 340 is formed on the horizontal guide part 320. The vertical guide hole 340 is used to guide the lifting and lowering of the loading column 400. The loading column 400 includes a lifting column 410 and a push-pull motor 420. The lifting column 410 is coaxially arranged in the vertical guide hole 340 and slidably connected to the horizontal guide part 320, that is, the lifting column 410 can be lifted and lowered. The push-pull motor 420 is located directly above the lifting column 410 and is fixedly connected to the connecting part 310. The push-pull end of the push-pull motor 420 (also called a push rod motor) is connected to the lifting column 410 and is used to drive the lifting column 410 to lift and lower.

[0078] This configuration is because: by fixing the horizontal guide 320 to one side of the connecting part 310 and sliding the lifting column 410 to the horizontal guide 320, the guiding effect of the horizontal guide 320 on the lifting column 410 can be used to limit the movement direction of the lifting column 410, thereby accurately applying the loading force to the loading position of the composite material reinforced wall panel 700; at the same time, by fixing the push-pull motor 420 to the top of the lifting column 410, the speed of the push-pull motor 420 can be controlled by the controller 600 to achieve precise control of the lifting and lowering of the lifting column 410 and the loading force, thereby improving the accuracy of the profile adjustment of the composite material reinforced wall panel 700.

[0079] An embodiment of an automatic adjustment method for the profile of a composite material reinforced wall panel includes the following steps:

[0080] S10: Obtain the deformation location of the composite material stiffened wall panel 700, and determine the loading location and the deformation amount Δx at the loading location based on the deformation location.

[0081] S20: First, calculate the elastic coefficient K using the Navierian solution formula for simply supported rectangular thin plates. ij ;

[0082] The Navierian solution formula is as follows:

[0083] a represents the transverse length of the composite reinforced wall panel 700; b represents the longitudinal length of the composite reinforced wall panel 700.

[0084] (ξ, η) are the position coordinates of the applied force F (that is, the coordinates of the applied position); (x, y) are the position coordinates of Δx;

[0085] D is the bending stiffness of the wall panel, calculated using the following formula:

[0086] E is the elastic modulus; t is the wall thickness; μ is Poisson's ratio.

[0087] Then the deformation Δx and the elastic coefficient K ij Substituting into Hooke's Law, we can calculate the theoretical loading force F at each loading location; where Hooke's Law is:

[0088] S30: Compare the theoretical loading force F with the loading force threshold F0. If the theoretical loading force F is less than the loading force threshold F0, then execute S40. If the theoretical loading force F is greater than or equal to the loading force threshold F0, then increase the number of loading positions and recalculate the theoretical loading force F until the theoretical loading force F is less than the loading force threshold F0.

[0089] S40: Simultaneously apply adjusting loading force to all loading positions until the adjusting loading force is equal to the theoretical loading force.

[0090] In a specific embodiment, a method for automatic adjustment of the profile of a composite material reinforced wall panel includes the following steps:

[0091] The basic parameters of the composite material reinforced wall panel 700 in this embodiment are as follows: a = b = 1m, and the thickness is 2.4mm.

[0092] S10: First, test the composite material reinforced wall panel 700 to determine the deformation position on the composite material reinforced wall panel 700; then, based on the deformation position, determine the loading position of the composite material reinforced wall panel 700 simply supported on the support base 100 and the deformation amount Δx at each loading position.

[0093] In this embodiment, after testing, the coordinates of the three loading positions on the same cross section of the composite material reinforced wall panel 700 are (200,200), (500,200), and (800,200), and the deformation amounts at the three loading positions are 2.35mm, 4mm, and 2.35mm, respectively.

[0094] Then, adjust the longitudinal position of the positioning beam 200 on the support base 100 and the lateral position of the positioning frame 300 on the positioning beam 200 according to the loading position, until the loading column 400 is located directly above the loading position.

[0095] S20: First, calculate the elastic coefficient k using the Navierian solution formula for simply supported rectangular thin plates. ij .

[0096] The Navierian solution formula for simply supported rectangular thin plates is:

[0097]

[0098] Taking the second-order approximation of the Navierian solution formula as follows:

[0099]

[0100] in,

[0101] Substituting E = 30000 MPa, t = 2.4 mm, and μ = 0.6 into the above formula, we can calculate D = 54 N·m.

[0102] Substituting the known parameters into the above formula yields the elastic progress coefficient k. ij :

[0103]

[0104] Hooke's Law is formulated as follows:

[0105] The deformation Δx and elastic coefficient K ij Substituting into Hooke's Law, the theoretical loading forces of the three loading columns at the three deformation positions can be calculated as F1 = 5.3 N, F2 = 9.3 N, and F3 = 5.3 N.

[0106] S30: Compare the theoretical loading force F with the loading force threshold F0; In this embodiment, the loading force threshold F0 of the composite material stiffened wall panel 700 is 50N, which means that the theoretical loading force at the three loading positions is less than the loading force threshold F0.

[0107] S40: The computer controls three loading columns 400 to simultaneously apply adjusting loading forces to three loading positions, and the sensor 500 obtains the magnitude of the adjusting loading force until the adjusting loading force is equal to the theoretical loading force F.

[0108] Finally, the profile of the composite reinforced wall panel 700 was inspected again and found to meet the design requirements.

[0109] Compared with the prior art, this application has at least the following beneficial technical effects:

[0110] This application provides a plurality of positioning beams 200 above the composite material reinforced wall panel 700, and a plurality of positioning frames 300 with loading columns 400 are installed on the positioning beams 200, which can simultaneously adjust multiple deformation positions of the composite material reinforced wall panel 700.

[0111] This application utilizes the Navierian solution for simply supported rectangular thin plates and Hooke's law. Based on the detected deformation of the composite reinforced wall panel 700, the number of loading columns 400 and the load value applied by each loading column 400 to the composite reinforced wall panel 700 can be accurately calculated, ensuring the accuracy of the surface adjustment of the composite reinforced wall panel 700.

[0112] This application uses a controller 600 (such as a computer) to control a push-pull motor 420 to apply a vertical load to the composite material reinforced wall panel 700. The adjustment of the surface of the composite material reinforced wall panel 700 can be completed in one loading operation, which not only reduces labor intensity but also improves accuracy and work efficiency.

[0113] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
