Description
Technical Field
[0001] This application relates to the field of drop finite element simulation technology, and in particular to a simulation method, simulation device, electronic device and storage medium for mobile phone drop simulation. Background Technology
[0002] When conducting drop tests on mobile phones, the phone is dropped from six sides, four corners, and various small angles. Furthermore, the drop height is not a fixed value and needs to be adjusted according to the actual test. In related technologies, simulating different drop postures requires manual adjustment of the drop posture and height, resulting in low simulation efficiency. Summary of the Invention
[0003] The main technical problem addressed by this application is to provide a method, device, electronic device, and storage medium for simulating mobile phone drops, which can improve simulation efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is to provide a simulation method for mobile phone drop. The simulation method includes: establishing a mobile phone model and a floor model, obtaining the mobile phone coordinates of the mobile phone model and the center point coordinates of the floor model; adjusting the mobile phone coordinates and the center point coordinates according to different drop postures of the mobile phone, wherein, when the drop posture is a non-vertical drop, the mobile phone coordinates and the center point coordinates are adjusted by translation; when the drop posture is a vertex drop, the mobile phone coordinates and the center point coordinates are adjusted by translation and rotation; and substituting the automatically located mobile phone coordinates and the center point coordinates under different drop postures into a finite element solver for solving to obtain the simulation results of different drop postures of the mobile phone.
[0005] As described above, by translating and rotating the model's coordinates, the precise positioning of the phone in different drop postures can be obtained without manually adjusting the drop posture and height, thus improving simulation efficiency. Furthermore, the coordinates of the phone in different drop postures obtained by this method have high accuracy and small error.
[0006] In one possible implementation, the phone coordinates are the maximum external shape coordinates of the phone model, wherein the maximum external shape coordinates are the coordinates corresponding to the maximum position value of the phone model in each axis.
[0007] As mentioned above, the maximum external coordinates better reflect the outline of the phone, resulting in higher simulation accuracy.
[0008] In one possible implementation, the step of adjusting the phone coordinates and the center point coordinates according to different drop postures of the phone specifically includes: determining whether the phone's drop posture is a top-angle drop; if the phone's drop posture is a top-angle drop, adjusting the phone coordinates and the center point coordinates by translation and rotation; if the phone's drop posture is not a top-angle drop, adjusting the center point coordinates by translation while keeping the phone coordinates unchanged.
[0009] The above method can obtain the precise coordinates of the phone in different drop postures.
[0010] In one possible implementation, the step of adjusting the center point position coordinates by translation specifically includes: determining the drop direction of the mobile phone; the center point of the floor model is located at the center of the mobile phone model; translating the center point in the drop direction until the floor model and the mobile phone model are tangent to obtain the adjusted center point position coordinates.
[0011] The above method can obtain the coordinates of the non-top-angle drop posture of the mobile phone by translation.
[0012] In one possible implementation, the simulation method further includes: obtaining the thickness of the mobile phone model and the thickness of the floor model in the direction of the mobile phone's fall; and shifting the center point in the direction of the fall by half the sum of the thickness of the mobile phone model and the thickness of the floor model to obtain the adjusted coordinates of the center point position.
[0013] The above makes the height of the phone more accurate during drop simulation.
[0014] In one possible implementation, the step of adjusting the coordinates of the mobile phone and the coordinates of the center point by translation and rotation specifically includes: determining the drop angle and drop direction of the mobile phone; rotating the mobile phone model in the forward direction according to the drop angle; translating the center point in the drop direction until the floor model and the mobile phone model are tangent; and rotating the center point and the mobile phone model together in the reverse direction according to the drop angle to obtain the adjusted coordinates of the center point.
[0015] The above method can obtain the coordinates of the phone's top corner falling posture through translation and rotation.
[0016] In one possible implementation, the mobile phone model and the floor model are created using modeling software.
[0017] The above can be used to create mobile phone models and floor models.
[0018] To address the aforementioned technical problems, this application also proposes a simulation device that applies the simulation method described above. The simulation device includes an acquisition module, an adjustment module, and a simulation module. The acquisition module is used to establish a mobile phone model and a floor model, acquiring the mobile phone coordinates of the mobile phone model and the center point coordinates of the floor model. The adjustment module is used to adjust the mobile phone coordinates and the center point coordinates according to different drop postures of the mobile phone. Specifically, when the drop posture is a non-vertical drop, the mobile phone coordinates and the center point coordinates are adjusted by translation; when the drop posture is a vertex drop, the mobile phone coordinates and the center point coordinates are adjusted by translation and rotation. The simulation module is used to substitute the automatically located mobile phone coordinates and the center point coordinates under different drop postures into a finite element solver for solving, thereby obtaining simulation results for different drop postures of the mobile phone.
[0019] As described above, by translating and rotating the model's coordinates, the precise positioning of the phone in different drop postures can be obtained without manually adjusting the drop posture and height, thus improving simulation efficiency. Furthermore, the coordinates of the phone in different drop postures obtained by this method have high accuracy and small error.
[0020] To address the aforementioned technical problems, this application also proposes an electronic device comprising: a processor; and a memory connected to the processor for storing a computer program executable on the processor; wherein the processor implements the aforementioned simulation method when executing the computer program.
[0021] To address the aforementioned technical problems, this application also proposes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the simulation method described above.
[0022] The beneficial effects of this application are as follows: Unlike the prior art, this application provides a simulation method, simulation device, electronic device and storage medium for mobile phone drop simulation. The simulation method translates and rotates the coordinates of the model, which can obtain the accurate positioning of the mobile phone in different drop postures. It does not require manual adjustment of the drop posture and height, thus improving the simulation efficiency. Moreover, the coordinates of the mobile phone in different drop postures obtained by this method have high accuracy and small error. Attached Figure Description

[0039] Existing drop simulations require manual adjustment of the drop attitude and height for different drop postures, resulting in low simulation efficiency.
[0040] To address the aforementioned problems, this application proposes a simulation method, simulation device, electronic device, and storage medium for mobile phone drop simulation. By translating and rotating the model's coordinates, precise positioning of the mobile phone in different drop postures can be obtained, effectively solving the above-mentioned problems.
[0041] The following describes in detail the mobile phone drop simulation method, simulation device, electronic device, and storage medium provided in this application with reference to the accompanying drawings and embodiments.
[0042] Please see Figure 1 , Figure 1 This is a flowchart illustrating one implementation method of the mobile phone drop simulation method of this application.
[0043] In this embodiment, a mobile phone is used as an example of the object being dropped for explanation. In some other embodiments, the simulation method can also be used to simulate drops on any reasonable type of product such as tablets and water cups. This embodiment does not limit this.
[0044] S11: Create a mobile phone model and a floor model, and obtain the mobile phone coordinates of the mobile phone model and the center point coordinates of the floor model.
[0045] In this embodiment, the drop posture of the mobile phone includes non-corner drop and corner drop. Non-corner drop includes dropping from all six sides of the mobile phone, and corner drop includes dropping from the four corners of the mobile phone to the ground. Corner drop also includes dropping from each corner of the mobile phone to the ground at different tilt angles.
[0046] In this embodiment, the modeling software is Hypermesh (a finite element modeling software), which is used to create the mobile phone model and the floor model. In other embodiments, other modeling software such as ANSYS / Workbench (an integrated finite element analysis software) and Abaqus (an engineering simulation finite element software) can also be used for modeling. Furthermore, when generating the floor model in Hypermesh, the parameters of the floor model can be set; for example, the floor model can be set to wood flooring, cement flooring, marble flooring, etc.
[0047] In some preferred embodiments, the coordinates of the mobile phone are the maximum external coordinates of the mobile phone model, where the maximum external coordinates are the coordinates corresponding to the maximum position value of the mobile phone model in each axis. Please refer to [link to relevant documentation]. Figure 2 , Figure 2 yes Figure 1 A flowchart illustrating a specific implementation of obtaining the maximum external coordinates of a mobile phone model; in some implementations, the step of obtaining the maximum external coordinates of the mobile phone model may include:
[0048] S111: Establish a reference coordinate system.
[0049] S112: Determine the coordinates of the reference point of the mobile phone model.
[0050] S113: Measure the endpoint coordinates of the mobile phone model.
[0051] S114: Calculate the maximum dimensions of the mobile phone model in each axis to obtain the maximum external coordinates of the mobile phone model.
[0052] In this embodiment, the reference coordinate system is a spatial rectangular coordinate system. In this implementation, the drop simulation only simulates a non-flipping drop of the phone on a two-dimensional plane; therefore, the maximum external coordinates of the phone in the thickness direction are not calculated. Preferably, the endpoint coordinates are the coordinates of the four vertex corners of the large surface of the phone model.
[0053] In this step, the center point of the floor model is not the coordinate of the floor model falling in different postures into the finite element solver, but an initial coordinate before the floor model is adjusted. In this step, preferably the center point of the board model is located at the center of the mobile phone model, and the coordinate of the center point of the floor model is (0,0,0).
[0054] S12: Adjust the phone coordinates and center point coordinates according to the different drop postures of the phone. Specifically, when the drop posture is not a top-angle drop, the phone coordinates and center point coordinates are adjusted by translation; when the drop posture is a top-angle drop, the phone coordinates and center point coordinates are adjusted by translation and rotation.
[0055] Please see Figure 3 , Figure 3 yes Figure 1 A flowchart illustrating one embodiment of S12; in some embodiments, S12 may specifically include:
[0056] S121: Determine whether the phone was dropped from a top angle.
[0057] If the phone is dropped from a top angle, then execute S122; if the phone is dropped from a non-top angle, then execute S123.
[0058] S122: Adjust the coordinates of the mobile phone and the center point by translation and rotation.
[0059] S123: Adjust the coordinates of the center point by translation while keeping the coordinates of the mobile phone unchanged.
[0060] In a specific application scenario, the phone's drop posture is determined to be a non-vertical drop, with the phone falling to the left, such as... Figure 4 As shown, Figure 4 This is a schematic diagram of the model positioning structure for a non-vertical drop and a leftward drop of the mobile phone, as per this application. Before adjusting the mobile phone coordinates and the center point coordinates, the center point coordinates of the floor model are located at the center of the mobile phone coordinates. To obtain accurate positioning coordinates for a leftward drop of the mobile phone, the center point of the floor model is shifted to the left, making the floor model tangent to the mobile phone model. After shifting the center point, the adjusted center point coordinates and the mobile phone coordinates are the positioning coordinates for a non-vertical drop and a leftward drop of the mobile phone.
[0061] In some preferred embodiments, the step of translating the center point of the floor model to make it tangent to the phone model specifically includes: obtaining the thickness of the phone model and the thickness of the floor model in the direction of the phone's fall; and translating the center point in the direction of the fall by half the sum of the thicknesses of the phone model and the floor model to obtain the adjusted center point position coordinates. By first determining the distance the center point needs to be translated, and then controlling the translation of the center point by this distance, the accuracy of the phone coordinates and center point position coordinates under different fall postures can be improved.
[0062] In another specific application scenario, to determine if the phone's drop posture is a non-vertical drop, as shown in the figure, before adjusting the phone's coordinates and the center point's position coordinates, the center point's position coordinates of the floor model are located at the center of the phone's coordinates. To obtain the accurate positioning coordinates of the phone's drop, the center point of the floor model is translated downwards, making the floor model tangent to the phone model. After translating the center point, the adjusted center point's position coordinates and the phone's coordinates are the positioning coordinates of the phone's non-vertical drop.
[0063] In another specific application scenario, to determine whether the phone's drop posture is a top-angle drop or a drop from the upper left corner, we can first rotate the phone model to the left, then translate the center point of the floor model to the left so that the floor model and the phone model are tangent. After the floor model and the phone model are tangent, rotate the floor model and the phone model as a whole in the opposite direction to the right. The coordinates of the center point after rotation and the coordinates of the phone model are the positioning coordinates of the phone's top-angle drop and the phone's upper left corner drop.
[0064] Further, please refer to Figure 5 , Figure 5 This is a flowchart illustrating one embodiment of the present application's method of adjusting the coordinates of the mobile phone and the center point using translation and rotation. In some embodiments, the steps for adjusting the coordinates of the mobile phone and the center point using translation and rotation specifically include:
[0065] S1221: Determine the drop angle and direction of the mobile phone.
[0066] S1222: Rotate the phone model forward according to the drop angle; translate the center point in the drop direction until the floor model is tangent to the phone model.
[0067] S1223: Rotate the center point and the mobile phone model in the opposite direction according to the drop angle to obtain the adjusted center point position coordinates.
[0068] For example, if a phone is dropped at a 30-degree angle from the top left corner, first rotate the phone model 30 degrees counterclockwise to the left. (See [reference needed]). Figure 6 , Figure 6 This application presents a structural diagram showing the phone model rotated 30 degrees counterclockwise to the left; then, the thickness of the phone model and the thickness of the floor model are obtained in the direction of the phone's fall; the center point is shifted in the direction of the fall by half the sum of the thickness of the phone model and the thickness of the floor model, so that the floor model and the phone model are tangent. (See reference...) Figure 7 , Figure 7 This is a schematic diagram showing the structure of the floor model and the mobile phone model tangent after the center point of this application has been translated; then, the center point of the floor model and the mobile phone model are rotated together 30 degrees clockwise to the right, see reference. Figure 8 , Figure 8This is a schematic diagram of the structure in this application where the center point of the floor model and the mobile phone model are rotated 30 degrees clockwise to the right; the coordinates of the center point after rotation and the coordinates of the mobile phone model are the positioning coordinates of the upper left corner of the mobile phone when it is tilted and dropped at a 30-degree angle.
[0069] When the phone is dropped at a 45-degree angle from the bottom right corner, first rotate the phone model 45 degrees clockwise to the right. Then, obtain the thickness of the phone model and the thickness of the floor model in the direction of the phone's fall. Shift the center point in the direction of the fall by half the sum of the thickness of the phone model and the floor model, making the floor model tangent to the phone model. Then, rotate the center point of the floor model and the phone model together counterclockwise to the left by 45 degrees. The coordinates of the center point after rotation and the coordinates of the phone model are the positioning coordinates of the phone's bottom right corner when it is dropped at a 45-degree angle.
[0070] S13: Substitute the coordinates of the mobile phone and the coordinates of the center point obtained by automatic positioning under different drop postures into the finite element solver to obtain the simulation results of the mobile phone under different drop postures.
[0071] When substituting the coordinates of the phone and the center point of the phone, which are located in different drop postures, into the solution, it is also necessary to input boundary conditions for the model. Boundary conditions can include the gravity applied to the phone model, the initial velocity of the phone model, and the drop height of the phone model.
[0072] Unlike existing technologies, this application provides a simulation method for mobile phone drop simulation. This method includes: establishing a mobile phone model and a floor model; obtaining the mobile phone coordinates and the center point coordinates of the floor model; adjusting the mobile phone coordinates and the center point coordinates according to different drop postures of the mobile phone; specifically, adjusting the mobile phone coordinates and the center point coordinates by translation when the drop posture is not a top-angle drop; adjusting the mobile phone coordinates and the center point coordinates by translation and rotation when the drop posture is a top-angle drop; and substituting the automatically located mobile phone coordinates and the center point coordinates under different drop postures into a finite element solver for solving to obtain simulation results for different drop postures. The above-mentioned translation and rotation of the model's coordinates allows for precise positioning of the mobile phone under different drop postures, eliminating the need for manual adjustment of the drop posture and height, thus improving simulation efficiency. Furthermore, this method yields high accuracy and small error in the coordinates of the mobile phone under different drop postures.

Specifically, when the drop posture is a non-vertical drop, the mobile phone coordinates and the center point coordinates are adjusted by translation; when the drop posture is a vertex drop, the mobile phone coordinates and the center point coordinates are adjusted by translation and rotation. The simulation module 130 is used to substitute the mobile phone coordinates and the center point coordinates under different drop postures of the mobile phone into a finite element solver for solving to obtain the simulation results of different drop postures of the mobile phone.

[0077] In some embodiments, the simulation method further includes: obtaining the thickness of the mobile phone model and the thickness of the floor model in the direction of the mobile phone's fall; and shifting the center point in the direction of the fall by half the sum of the thickness of the mobile phone model and the thickness of the floor model to obtain the adjusted coordinates of the center point position.
