Description

Technical Field

[0001] This invention relates to the field of automotive glass manufacturing technology, and more specifically to a method and apparatus for determining automotive glass production processes. Background Technology

[0002] Automotive glass can be categorized by its installation location, such as windshield, rear windshield, door glass, triangular window glass, and sunroof glass. Different types of automotive glass typically require different manufacturing processes, so it is necessary to select the appropriate automotive glass manufacturing process when designing automotive glass.

[0003] To meet the safety and aesthetic requirements of automobiles, automotive glass requires curved glass sheets with appropriate strength. The automotive glass manufacturing process primarily involves processing flat glass sheets into curved sheets that meet usage requirements. This includes heating and softening steps, bending and shaping steps, and annealing and cooling steps. Different heating and softening steps, different bending and shaping steps, and / or different annealing and cooling steps can produce automotive glass with varying strengths. When designing automotive glass, designers need to select appropriate manufacturing processes to meet surface stress requirements. However, there is no direct relationship between surface stress values ​​and manufacturing processes. Designers often choose processes based on experience, which carries the risk that automotive glass produced using experience-based processes may not meet surface stress requirements. This can lead to significant increases in production costs and reduced production efficiency due to adjustments to the manufacturing process and restarting production. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0033] As safety glass, automotive glass must meet relevant safety requirements, such as impact resistance (e.g., resistance to penetration and impact). When designing automotive glass, only surface stress values ​​are typically required; however, these values ​​alone cannot accurately and directly select a suitable manufacturing process. After automotive glass production, surface stress meters are usually used to measure stress values ​​at multiple points on the glass surface. The stress values ​​on the glass surface vary with the measurement location, and different people measuring the surface stress values ​​can produce significantly different results. This makes it difficult to accurately correlate stress values ​​with the manufacturing process, further hindering the selection of a suitable manufacturing process during automotive glass design. Therefore, this invention proposes a method for determining the manufacturing process of automotive glass, which can accurately determine the manufacturing process of the automotive glass to be produced based on its technical requirements.

[0034] The execution subject of the method for determining the automotive glass manufacturing process provided in this embodiment of the invention includes, but is not limited to, a computer.

[0035] Figure 1This is a flowchart illustrating the method for determining the automotive glass manufacturing process provided in the first embodiment of the present invention, as shown below. Figure 1 As shown, the method for determining the automotive glass manufacturing process provided in this embodiment of the invention includes:

[0036] S101. Obtain the technical requirements for the automotive glass to be produced, including automotive glass parameters and target load;

[0037] Specifically, the technical requirements for the automotive glass to be produced can be obtained, including information such as automotive glass parameters and target load.

[0038] Automotive glass parameters include, but are not limited to, the length, width, and thickness of a single pane of glass; the length, width, and thickness of the two panes of glass used in laminated glass, as well as the length, width, and thickness of the interlayer film; and the length, width, thickness, radius of curvature, and length, width, and thickness of the two panes of glass used in component-level automotive glass, as well as the length, width, and thickness of the interlayer film. The target load is equal to the minimum force required to crush the automotive glass, which can usually be obtained directly from the customer during design input or obtained by converting the customer's required parameters.

[0039] For example, automotive glass parameters include a single pane of glass with a length of 145cm, a width of 20cm, and a thickness of 2mm; laminated glass uses two single panes of glass with a length of 145cm, a width of 20cm, and a thickness of 2mm, and an interlayer with a length of 145cm, a width of 20cm, and a thickness of 0.76mm; component-level automotive glass used as a windshield uses two single panes of glass with a length of 120cm, a width of 110cm, thicknesses of 2mm and 1.8mm, a radius of curvature of 5000mm, and an interlayer with a length of 120cm, a width of 110cm, and a thickness of 0.76mm.

[0040] S102. Establish a component-level simulation model of the automotive glass based on the automotive glass parameters;

[0041] Specifically, the simulation model of the component-level automotive glass in this embodiment of the invention includes the component-level automotive glass and a support component. The component-level automotive glass can be fixed to the support component by means of bonding or other methods. The component-level automotive glass is a curved laminated glass, which includes at least two curved monolithic glass panes and an interlayer film sandwiched between the two monolithic glass panes. Based on the automotive glass parameters, a simulation model of a flat monolithic glass pane can be established first, then a simulation model of a flat laminated glass pane can be established based on the simulation model of the flat monolithic glass pane, and finally a simulation model of the component-level automotive glass pane can be established based on the simulation model of the flat laminated glass pane. The simulation parameters required to establish the simulation model of the component-level automotive glass pane can be determined based on the simulation models of the flat monolithic glass pane and the flat laminated glass pane. Each simulation model can be established using simulation software, including but not limited to Abaqus, Ansys, Marc, Comsol, etc., selected according to actual needs; this embodiment of the invention does not impose any limitations.

[0042] S103. Based on the simulation parameters corresponding to various automotive glass manufacturing processes, a strength simulation test is conducted on the simulation model of the component-level automotive glass to obtain the minimum force value of the component-level automotive glass corresponding to each automotive glass manufacturing process; wherein, the simulation parameters corresponding to different automotive glass manufacturing processes are obtained in advance.

[0043] Specifically, under the simulation parameters corresponding to each automotive glass manufacturing process, a strength simulation test is conducted on the simulation model of the component-level automotive glass to obtain the maximum and minimum force values ​​of the component-level automotive glass corresponding to each automotive glass manufacturing process. The strength simulation test refers to a strength experiment performed in simulation software. The maximum force value of the component-level automotive glass corresponding to the automotive glass manufacturing process is the maximum load that the component-level automotive glass produced by the aforementioned manufacturing process can withstand when it fails in the strength simulation test, assuming that the first stress limit value of a single glass sample is used as the maximum stress value of a single glass piece constituting the component-level automotive glass. The minimum force value of the component-level automotive glass corresponding to the automotive glass manufacturing process is the maximum load that the component-level automotive glass produced by the aforementioned manufacturing process can withstand when it fails in the strength simulation test, assuming that the second stress limit value of a single glass sample is used as the maximum stress value of a single glass piece constituting the component-level automotive glass. The strength test for the component-level automotive glass includes, but is not limited to, static pressure testing, and is selected according to actual needs; this embodiment of the invention does not impose limitations. The component-level simulation parameters corresponding to each automotive glass manufacturing process are obtained in advance.

[0044] The automotive glass manufacturing process can include heating and softening steps, bending and forming steps, and annealing and cooling steps. Different automotive glass manufacturing processes can produce automotive glass with different strengths.

[0045] The heating and softening step is used to heat the glass plate to a softening temperature of 500℃ to 800℃. The heating and softening step can employ radiant heating (A1) and / or convection heating (A2). Radiant heating uses resistive elements, gas radiation, etc., to heat the glass plate; convection heating uses hot air convection, etc., to heat the glass plate.

[0046] The bending and forming step is used to give the heated and softened glass sheet its final bent shape. This step can employ at least one of the following processes: gravity bending (B1), roller bending (B2), pressing bending (B3), and suction bending (B4). Gravity bending utilizes the glass sheet's own weight and a gravity bending mold to bend it into shape. Roller bending uses paired bending rollers to press the glass sheet into shape. Press bending uses convex and concave molds to press the glass sheet into shape. Suction bending uses vacuum holes in a convex or concave mold to adhere the glass sheet to its forming surface, thus bending it into shape.

[0047] The annealing cooling step is used to anneal and cool the glass plate with the final curved shape to obtain curved glass plates of different strengths. The annealing cooling step can be performed using either convection annealing or radiation annealing. Convection annealing (C1) uses cold air and / or water mist for annealing cooling; radiation annealing (C2) uses a cooler material placed opposite the glass, and the radiative heat exchange results in greater localized cooling of the glass plate area facing the material.

[0048] Combining the above-mentioned heating and softening steps, bending and forming steps, and annealing and cooling steps can yield different automotive glass manufacturing processes, as exemplified below:

[0049] Automotive glass manufacturing process A1+B1+C1; Automotive glass manufacturing process A1+B2+C1; Automotive glass manufacturing process A1+B3+C1; Automotive glass manufacturing process A1+B4+C1; Automotive glass manufacturing process A1+B1+C2; Automotive glass manufacturing process A1+B2+C2; Automotive glass manufacturing process A1+B3+C2; Automotive glass manufacturing process A1+B4+C2; Automotive glass manufacturing process A2+B1+C1; Automotive glass manufacturing process A2+B2+C1; Automotive glass manufacturing process A2+B3+C1; Automotive glass manufacturing process A2+B4+C2.

[0050] Simulation parameters corresponding to the various automotive glass manufacturing processes mentioned above can be obtained in advance and used for strength simulation tests of component-level automotive glass simulation models, thereby accelerating the simulation test efficiency of component-level automotive glass simulation models.

[0051] S104. If it is determined that there is a minimum force value greater than the target load, then the production process of the automotive glass to be produced is obtained based on the automotive glass production process corresponding to the minimum force value greater than the target load.

[0052] Specifically, the minimum force value corresponding to each automotive glass manufacturing process is compared with the target load. If there is a minimum force value greater than the target load, it means that the automotive glass manufacturing process corresponding to the minimum force value greater than the target load can produce automotive glass that meets the target load. If there is only one minimum force value greater than the target load, then the automotive glass manufacturing process corresponding to the minimum force value greater than the target load is used as the manufacturing process for the automotive glass to be produced. If there are multiple minimum force values ​​greater than the target load, then one automotive glass manufacturing process corresponding to the multiple minimum force values ​​greater than the target load can be selected as the manufacturing process for the automotive glass to be produced. The manufacturing process for the automotive glass to be produced can be selected based on factors such as yield rate, production cost, or production cycle time.

[0053] The method for determining the automotive glass manufacturing process provided in this invention can more accurately obtain the manufacturing process of the automotive glass to be manufactured, improve the reliability of the determination of the automotive glass manufacturing process, and reduce or even avoid re-production due to inappropriate selection of the manufacturing process, thereby reducing the production cost of automotive glass and improving production efficiency.

[0054] Figure 2 This is a flowchart illustrating the method for determining the automotive glass manufacturing process provided in the second embodiment of the present invention, as shown below. Figure 2 As shown, based on the above embodiments, the steps for obtaining simulation parameters corresponding to different automotive glass manufacturing processes further include:

[0055] S201. Conduct single-piece glass strength simulation tests based on single-piece glass samples under each automotive glass manufacturing process to obtain simulation parameters of single-piece glass samples under each automotive glass manufacturing process.

[0056] Specifically, simulation models of single-piece glass samples under each automotive glass manufacturing process are established in simulation software. Then, single-piece glass strength simulation tests are conducted to obtain simulation parameters for each automotive glass manufacturing process. The single-piece glass strength simulation test can be a four-point bending test or a three-point bending test performed in the simulation software. The simulation parameters for each automotive glass manufacturing process include, but are not limited to, the material parameters of the single-piece glass, the constitutive model of the material of the single-piece glass sample, the element shape, element order, mesh size, and coefficient of friction. The length, width, and thickness of the single-piece glass sample are prepared according to testing standards. Material parameters include, but are not limited to, Young's modulus, Poisson's ratio, and density. Element shapes include, but are not limited to, tetrahedral elements, hexahedral elements, and wedge elements. Element orders include, but are not limited to, linear elements, quadratic elements, and modified quadratic elements.

[0057] S202. Based on the simulation parameters of the laminated glass sample composed of single glass samples under each automotive glass production process and the single glass sample under each automotive glass production process, a laminated glass strength simulation test is conducted to obtain the simulation parameters of the laminated glass sample under each automotive glass production process.

[0058] Specifically, simulation models of laminated glass samples under each automotive glass manufacturing process are established in simulation software. Then, laminated glass strength simulation tests are conducted to obtain simulation parameters for the laminated glass samples under each automotive glass manufacturing process. The simulation model of the laminated glass sample under each automotive glass manufacturing process includes a simulation model of a single-piece glass sample under that process. During the laminated glass strength simulation test, the simulation parameters of the single-piece glass sample under each automotive glass manufacturing process are kept constant. The laminated glass strength simulation test can be performed in the simulation software using either a four-point bending test or a three-point bending test. The simulation parameters of the laminated glass sample under each automotive glass manufacturing process include the simulation parameters of the corresponding single-piece glass sample, as well as the polymer material parameters used in the interlayer, the polymer constitutive model, unit shape, unit order, and mesh size. The interlayer thickness of the laminated glass sample is set according to actual needs; this embodiment of the invention does not limit this setting.

[0059] In order to facilitate simulation design and improve simulation efficiency, the single-piece glass sample is a flat single-piece glass, and the laminated glass sample is a flat laminated glass.

[0060] S203. Establish simulation models of component-level automotive glass samples under each automotive glass manufacturing process. Based on the simulation parameters of single-piece glass samples and laminated glass samples under each automotive glass manufacturing process, conduct component-level automotive glass strength simulation tests to obtain simulation parameters of component-level automotive glass samples under each automotive glass manufacturing process.

[0061] Specifically, a simulation model of a component-level automotive glass sample under each automotive glass manufacturing process is established in simulation software. Then, a strength simulation test of the component-level automotive glass sample is conducted to obtain the simulation parameters of the component-level automotive glass sample under each automotive glass manufacturing process. The simulation model of the component-level automotive glass sample under each automotive glass manufacturing process includes the component-level automotive glass and a support component. The component-level automotive glass is a curved laminated glass with parameters consistent with the actual automotive glass installed in the vehicle. During the strength simulation test of the component-level automotive glass sample, the simulation parameters of the curved laminated glass under each automotive glass manufacturing process are kept unchanged. The strength simulation test of the component-level automotive glass sample can be a static pressure test performed in the simulation software. The simulation parameters of the component-level automotive glass sample under each automotive glass manufacturing process include the corresponding simulation parameters of the curved laminated glass, as well as the relative bonding position, bonding area, and bonding force between the curved laminated glass and the support component. The simulation parameters of the curved laminated glass are derived from the simulation parameters of the laminated glass sample obtained in step S202. The support component of the component-level automotive glass sample is set according to actual needs, and this embodiment of the invention does not impose limitations.

[0062] The static pressure test involves placing the component-grade automotive glass onto a support structure identical to the vehicle frame, and then applying pressure to the center of the component-grade automotive glass at a speed of less than 10 mm / min to simulate static stress until the component-grade automotive glass breaks. Depending on the requirements, the component-grade automotive glass can be placed directly onto the support structure, or it can be placed on the support structure and then bonded together.

[0063] S204. Obtain the simulation parameters of the component-level automotive glass samples under each automotive glass manufacturing process, and use them as the simulation parameters corresponding to each automotive glass manufacturing process.

[0064] Specifically, simulation parameters for component-level automotive glass samples under each automotive glass manufacturing process are obtained and used as simulation parameters corresponding to each automotive glass manufacturing process. These simulation parameters for various automotive glass manufacturing processes are then used to conduct strength simulation tests during the determination of the manufacturing process for the automotive glass to be produced.

[0065] Based on the above embodiments, the monolithic glass sample is a flat monolithic glass, the laminated glass sample is a flat laminated glass, and the component-level automotive glass sample is a curved laminated glass.

[0066] Based on the above embodiments, the single-piece glass strength simulation test is a four-point bending or three-point bending test performed in simulation software; the laminated glass strength simulation test is a four-point bending or three-point bending test performed in simulation software; and the component-level automotive glass strength simulation test is a static pressure test performed in simulation software.

[0067] Figure 3 This is a flowchart illustrating the method for determining the automotive glass manufacturing process provided in the third embodiment of the present invention, as shown below. Figure 3 As shown, based on the above embodiments, the step of conducting single-piece glass strength simulation tests on single-piece glass samples under each automotive glass manufacturing process to obtain simulation parameters for single-piece glass samples under each automotive glass manufacturing process includes:

[0068] S301. Based on the single-piece glass sample under the automotive glass manufacturing process, establish a simulation model of the single-piece glass sample under the automotive glass manufacturing process.

[0069] Specifically, based on the single-piece glass sample produced under the aforementioned automotive glass manufacturing process, a simulation model of the single-piece glass sample under the aforementioned automotive glass manufacturing process is established in simulation software. The single-piece glass sample produced under the aforementioned automotive glass manufacturing process refers to a single-piece glass sample obtained through the aforementioned automotive glass manufacturing process. The single-piece glass sample is a flat, single-piece glass.

[0070] S302. Based on the first stress limit of the single-piece glass sample under the automotive glass manufacturing process, a strength simulation test is conducted on the simulation model of the single-piece glass sample under the automotive glass manufacturing process to obtain the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process; based on the second stress limit of the single-piece glass sample under the automotive glass manufacturing process, a strength simulation test is conducted on the simulation model of the single-piece glass sample under the automotive glass manufacturing process to obtain the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process.

[0071] Specifically, in the simulation software, the maximum stress value of the single glass sample under the automotive glass manufacturing process is set as the first stress limit value of the single glass sample under the automotive glass manufacturing process. A strength simulation test is performed on the simulation model of the single glass sample under the automotive glass manufacturing process, and the maximum load when the simulation model of the single glass sample is destroyed during the simulation test is recorded as the first simulation force value of the single glass sample under the automotive glass manufacturing process.

[0072] The maximum stress value of a single-piece glass specimen under the aforementioned automotive glass manufacturing process is set as the second stress limit value for the single-piece glass specimen under the aforementioned automotive glass manufacturing process. A strength simulation test is performed on a simulation model of the single-piece glass specimen under the aforementioned automotive glass manufacturing process. The maximum load at which the simulation model of the single-piece glass specimen fails during the strength simulation test is recorded as the second simulated force value of the single-piece glass specimen under the aforementioned automotive glass manufacturing process. The strength simulation test of the simulation model of the single-piece glass specimen under the aforementioned automotive glass manufacturing process can be a simulation test of a four-point bending test or a three-point bending test.

[0073] S303. If it is determined that the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process, and the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process, then the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test are obtained as the simulation parameters of the single-piece glass sample under the automotive glass manufacturing process; if it is determined that the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process does not match the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process, or the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process does not match the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process, then the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test are adjusted and the strength simulation test is repeated until the simulation parameters of the single-piece glass sample under the automotive glass manufacturing process are obtained.

[0074] Specifically, the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process is compared with the first force value of the single-piece glass sample under the automotive glass manufacturing process, and the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process is compared with the second force value of the single-piece glass sample under the automotive glass manufacturing process. If the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the first force value of the single-piece glass sample under the automotive glass manufacturing process, and the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the second force value of the single-piece glass sample under the automotive glass manufacturing process, then the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test are obtained as the simulation parameters of the single-piece glass sample under the automotive glass manufacturing process.

[0075] If the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process does not match the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process, or if the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process does not match the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process, then adjust the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test, and then repeat step S302 to re-perform the strength simulation test to obtain the first simulated force value and the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process. Then determine whether the re-obtained first simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the first simulated force value of the single-piece glass sample under the automotive glass manufacturing process, and whether the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process matches the second simulated force value of the single-piece glass sample under the automotive glass manufacturing process. If they both match, then obtain the simulation parameters of the single-piece glass sample under the automotive glass manufacturing process, and the simulation ends. If any mismatch is found, the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test are adjusted, and step S302 is repeated until the simulation parameters of the single-piece glass sample under the automotive glass manufacturing process can be obtained. When adjusting the simulation parameters of the simulation model of the single-piece glass sample under the automotive glass manufacturing process in the strength simulation test, the material parameters of the single-piece glass, the constitutive model of the material of the single-piece glass sample, the element shape, the element order, the mesh size, the coefficient of friction, etc., can be adjusted according to actual needs. This embodiment of the invention does not limit the adjustments.

[0076] The first and second stress limits of the single-piece glass sample under the automotive glass manufacturing process are obtained in advance. The first stress limit of the single-piece glass sample under the automotive glass manufacturing process can be obtained from the first stress value, and the second stress limit of the single-piece glass sample under the automotive glass manufacturing process can be obtained from the second stress value. The first stress value and the second stress limit of the single-piece glass sample under the automotive glass manufacturing process correspond to each other.

[0077] It should be noted that, in this embodiment of the invention, whether the first simulated force value matches the first force value can be determined by comparing the absolute value 'a' of the difference between the first simulated force value and the first force value with a threshold 'b'. If 'a' is less than or equal to 'b', then the first simulated force value matches the first force value; if 'a' is greater than 'b', then the first simulated force value does not match the first force value. The process for determining whether the second simulated force value matches the second force value is similar to the process for determining whether the first simulated force value matches the first force value, and will not be elaborated here.

Figure 4 As shown, based on the above embodiments, further, the laminated glass strength simulation test is conducted based on the simulation parameters of the laminated glass samples composed of single-pane glass samples under each automotive glass manufacturing process and the simulation parameters of the single-pane glass samples under each automotive glass manufacturing process. The simulation parameters of the laminated glass samples under each automotive glass manufacturing process include:

Based on the laminated glass sample composed of a single glass sample under the automotive glass manufacturing process and the simulation parameters of the single glass sample under the automotive glass manufacturing process, establish a simulation model of the laminated glass sample under the automotive glass manufacturing process; wherein, the simulation parameters of the single glass sample under the automotive glass manufacturing process include the first stress limit and the second stress limit of the single glass sample under the automotive glass manufacturing process.

[0080] Specifically, based on the laminated glass specimen composed of single-piece glass samples from the aforementioned automotive glass manufacturing process, a simulation model of the laminated glass specimen from the aforementioned automotive glass manufacturing process is established. The simulation model of the laminated glass specimen from the aforementioned automotive glass manufacturing process includes a simulation model of the single-piece glass sample, which adopts the simulation model of the single-piece glass sample from the aforementioned automotive glass manufacturing process, and applies the simulation parameters of the single-piece glass sample from the aforementioned automotive glass manufacturing process. The laminated glass specimen from the aforementioned automotive glass manufacturing process refers to a laminated glass specimen composed of single-piece glass samples.

Figure 6 As shown, based on the above embodiments, the steps for obtaining the first stress limit, second stress limit, first force value, and second force value of a single glass sample under the automotive glass manufacturing process further include:

[0107] S601. A strength test is conducted on a predetermined number of single glass samples under the automotive glass manufacturing process to obtain sample data of the force values ​​of the single glass samples under the automotive glass manufacturing process.

[0108] Specifically, for each automotive glass manufacturing process, a predetermined number of single-piece glass samples are obtained under that process. Then, a strength test is performed on each single-piece glass sample to obtain the magnitude of the force and the corresponding displacement value for each sample. Weibull statistical analysis is performed on the forces of the predetermined number of single-piece glass samples under the automotive glass manufacturing process to obtain sample data of the force values. The dimensions of the single-piece glass samples are prepared according to testing standards, and this embodiment of the invention does not limit the dimensions.

[0114]

[0115] Where, σ bB F represents the flexural strength of a single glass specimen, measured in megapascals (MPa). max L represents the maximum load corresponding to the moment a single glass specimen breaks, expressed in Newtons (N). s L represents the distance between the center lines of the two support rollers, in mm. b σ represents the distance between the center lines of the two bending rollers, in mm; B represents the width of a single glass sample, in mm; h represents the thickness of a single glass sample, in mm; bG The bending stress generated by the self-weight of a single glass sample is expressed in megapascals (MPa). ρ represents the density of a single glass sample, g represents the acceleration due to gravity, and k is a constant.

[0116] Let the first force value be F. max Substituting these values ​​into the above formula, the calculated bending strength of the single glass specimen is the first stress limit. The second force value is then taken as F. max Substituting these values ​​into the above formula, the calculated bending strength of a single glass sample is the second stress limit.

[0117] Based on the above embodiments, further, if it is determined that there is a minimum force value greater than the target load, then obtaining the production process of the automotive glass to be produced based on the automotive glass production process corresponding to the minimum force value greater than the target load includes:

[0118] If there are multiple minimum force values ​​greater than the target load, then according to the preset process screening rules, one automotive glass manufacturing process is selected from the automotive glass manufacturing processes corresponding to the multiple minimum force values ​​greater than the target load as the manufacturing process of the automotive glass to be produced.

[0119] Specifically, if there are multiple minimum force values ​​greater than the target load, then an automotive glass manufacturing process can be selected from the automotive glass manufacturing processes corresponding to the multiple minimum force values ​​greater than the target load according to preset process screening rules as the manufacturing process for the automotive glass to be produced. The process screening rules are preset and can be set according to factors such as yield rate, production cost, or production cycle time; this embodiment of the invention does not impose any limitations on these settings.

[0120] For example, the process selection rule could be: select the automotive glass manufacturing process with the highest yield; select the automotive glass manufacturing process with the lowest production cost; or select the automotive glass manufacturing process with the fastest production cycle.

[0121] Figure 7 This is a schematic diagram of the structure of the device for determining the automotive glass manufacturing process provided in the seventh embodiment of the present invention, as shown below. Figure 7 As shown, the device for determining the automotive glass manufacturing process provided in this embodiment of the invention includes an acquisition unit 701, a setup unit 702, a simulation unit 703, and a judgment unit 704, wherein:

[0122] The acquisition unit 701 is used to acquire the technical requirements of the automotive glass to be produced, including automotive glass parameters and target load; the establishment unit 702 is used to establish a simulation model of the component-level automotive glass based on the automotive glass parameters; the simulation unit 703 is used to conduct strength simulation tests on the simulation model of the component-level automotive glass based on the simulation parameters corresponding to various automotive glass production processes, and obtain the minimum force value corresponding to each automotive glass production process; wherein, the simulation parameters corresponding to different automotive glass production processes are obtained in advance; the judgment unit 704 is used to determine the production process of the automotive glass to be produced based on the automotive glass production process corresponding to the minimum force value greater than the target load after determining that there is a minimum force value greater than the target load.

[0123] Specifically, the acquisition unit 701 can acquire the technical requirements of the automotive glass to be produced, including information such as automotive glass parameters and target load. Automotive glass parameters include, but are not limited to, the length, width, and thickness of a single pane of glass, the interlayer thickness of laminated glass, and relevant data for component-level automotive glass.

[0124] In this embodiment of the invention, the component-level automotive glass includes laminated glass and a support member. The laminated glass can be fixed to the support member by means of bonding or other methods. The laminated glass includes at least two single-pane glass pieces, with an interlayer film sandwiched between each single-pane glass piece. The modeling unit 702 can, based on the automotive glass parameters, first establish a simulation model of the single-pane glass, then establish a simulation model of the laminated glass based on the simulation model of the single-pane glass, and finally establish a simulation model of the component-level automotive glass based on the simulation model of the laminated glass. Each simulation model can be established using simulation software, including but not limited to Abaqus, Ansys, Marc, Comsol, etc., selected according to actual needs; this embodiment of the invention does not impose any limitations.

[0125] Under the simulation parameters corresponding to each automotive glass manufacturing process, simulation unit 703 conducts strength simulation tests on the simulation model of the component-level automotive glass, thereby obtaining the maximum and minimum force values ​​of the component-level automotive glass corresponding to each automotive glass manufacturing process. The strength simulation test refers to a strength experiment performed in simulation software. The maximum force value of the component-level automotive glass corresponding to the automotive glass manufacturing process is the maximum load that the component-level automotive glass produced by the aforementioned automotive glass manufacturing process can withstand when it is destroyed in the strength simulation test, provided that the first stress limit value of a single glass sample is used as the maximum stress value of a single glass piece constituting the component-level automotive glass. The minimum force value of the component-level automotive glass corresponding to the automotive glass manufacturing process is the maximum load that the component-level automotive glass produced by the aforementioned automotive glass manufacturing process can withstand when it is destroyed in the strength simulation test, provided that the second stress limit value of a single glass sample is used as the maximum stress value of a single glass piece constituting the component-level automotive glass. The strength tests for the component-level automotive glass include, but are not limited to, static pressure tests, and are selected according to actual needs; this embodiment of the invention does not impose limitations. The component-level simulation parameters corresponding to each automotive glass manufacturing process are obtained in advance.

[0126] The judgment unit 704 compares the minimum force value corresponding to each automotive glass manufacturing process with the target load. If there is a minimum force value greater than the target load, it means that the automotive glass manufacturing process corresponding to the minimum force value greater than the target load can produce automotive glass that meets the target load. If there is only one minimum force value greater than the target load, then the automotive glass manufacturing process corresponding to the minimum force value greater than the target load is used as the manufacturing process for the automotive glass to be produced. If there are multiple minimum force values ​​greater than the target load, then one automotive glass manufacturing process can be selected from the multiple automotive glass manufacturing processes corresponding to the minimum force values ​​greater than the target load as the manufacturing process for the automotive glass to be produced. The manufacturing process for the automotive glass to be produced can be selected based on factors such as yield rate, production cost, or production cycle time.
