Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a method and device for setting the forward tilt of a simulation model. Background Art

[0002] In the related technologies, the demand for simulation has increased significantly to promote digital intelligent transformation, and the development time of consumer electronic products is short, so it is necessary to establish a system-level simulation model in a short time. Taking consumer electronic devices as an example, assuming that the electronic device is a laptop, the laptop generally has a foot pad made into a floor, but in mechanical design, the 3D diagram does not provide a schematic diagram of the foot pad supporting the floor. Therefore, there is a certain height difference between the front and rear foot pads on the 3D diagram. In the test setup of PA test items such as heavy block impact, vibration impact and LCD static pressure, the whole machine should be placed on the plane of the fixture or vibration table. In order to simulate individual PA test items, a corresponding simulation model must be established in the finite element software, and the simulation model must be rotated so that the lowest node and the second lowest node are in contact with the virtual plane respectively. Since the distribution positions of the lowest node and the second lowest node in each simulation model are different, it is difficult to find the correct rotation center and forward tilt angle in the simulation model, resulting in low modeling efficiency.

[0080] S102, determining movement parameter data based on the first data set, and constructing a second cube for the target object after it is moved based on the movement parameter data;

[0081] In some embodiments, determining the movement parameter data based on the first data set, and constructing a second cube for the target object moved based on the movement parameter data, includes:

[0083] A second cube is constructed based on the moved simulation model, and a second data set of the second cube is obtained; the second cube is the minimum circumscribed cube of the simulation model.

[0084] It can be understood that the movement parameter data includes the center point of the first cube on the first axis and the second axis, with the center point as the new coordinate origin; after determining the center point of the first axis and the second axis, the present application uses the center point as the new coordinate origin.

[0085] In some embodiments, determining the center point of the first cube on the first axis and the second axis based on the first data set, taking the center point as a new coordinate origin, and moving the center of the simulation model to the coordinate origin includes:

[0086] Determine the intersection of the horizontal axis and the vertical axis of the first cube, and use the intersection as the center point;

[0088] The center point coordinates are used as a new coordinate origin, and the center position of the simulation model is moved to the new coordinate origin.

The coordinates of the center point can be used Indicates that the simulation model is then translated from the center point coordinate to the coordinate origin (0,0,0) so that the coordinate origin is at the center point of the simulation model;

[0090] The second data set includes a third horizontal coordinate, a fourth horizontal coordinate, a third vertical coordinate, a fourth vertical coordinate, a third vertical coordinate and a fourth vertical coordinate;

[0091] Specifically, the smallest cube surrounding the moved simulation model, that is, the second cube, is obtained again, and the coordinates of the eight points of the second cube are obtained respectively. The six values ​​of the coordinates of the eight points can be expressed as X′ max , Y′ max , Z′ max , X′ min , Y′ min , Z′ min Indicates that, with six values ​​X max , Y max , Z max , X min , Y min , Z min Has the following relationship,

[0092]

[0093] Among them, the second cube is as follows Figure 4 shown.

[0094] S103, constructing a third cube based on the second data set of the second cube, and determining the lowest node coordinates and the second lowest node position based on the third data set of the third cube;

[0095] In some embodiments, the step of constructing a third cube based on the second data set of the second cube includes:

[0096] Based on the second data set, the plane where the lowest node of the second cube is located is used as the first virtual plane;

[0097] searching for a first node in the simulation model based on the first virtual plane;

[0098] A third cube is constructed based on all the searched first nodes.

[0099] It is understandable that, knowing that the lowest node is on the plane of y=0, it is necessary to establish a virtual plane of y=0 in the simulation model to search for all the nodes of the two pieces. The virtual plane passing through y=0 consists of four straight lines, namely z=Z′ max , z=Z′ min , x=X′ max , x=X′ min , where the virtual plane is Figure 5 shown.

[0100] The third data set includes a fifth horizontal coordinate, a sixth horizontal coordinate, a fifth vertical coordinate, a sixth vertical coordinate, a fifth vertical coordinate and a sixth vertical coordinate;

[0101] Specifically, the search node can be obtained based on the established virtual plane, and the smallest cube surrounding the search node, that is, the third cube, is obtained again to obtain the coordinates of eight points of the third cube. The coordinates of these eight points can be expressed by six numerical values ​​X max,1 , Y max,1 , Z max,1 , X min,1 , Y min,1 , Z min,1 express.

[0102] In some embodiments, determining the lowest node coordinates and the second lowest node position based on the third data set of the third cube includes:

[0103] Judging the two vertical axis coordinate values ​​in the third data set respectively according to the first judging condition;

[0104] Determine the position of the lowest node in the third cube according to the judgment result;

[0106] The two vertical coordinate values ​​in the third data set are judged respectively according to the second judgment condition, and the position of the corresponding second lowest node in the third cube is determined according to the judgment result.

[0107] Specifically, the relative position of the search node in the entire simulation model is determined in the following manner:

[0108] Z max,1 >0 and Z min,1 >0: Search node on front foot pad

[0109] Z max,1 <0 and Z min,1 <0: Search node on rear foot pad

[0110] by Figure 5 As an example, the simulation model shown in the figure searches for nodes that satisfy the above Z max,1 <0 and Z min,1 <0: Search node at rear foot pad, such as Figure 6 As shown, the first foot pad is the front foot pad, and the second foot pad is the rear foot pad.

[0111] Then the two values ​​Z max,1 , Zmin,1 Take the absolute value and compare the sizes, and use the following method to determine the Z plane where the lowest node is located.

[0112] |Z max,1 |>|Z min,1 |∶The lowest node is at z

[0113] =Z min,1 The plane with the lowest node coordinate (0,0,Z min,1 )

[0114] |Z max,1 |<|Z min,1 |∶The lowest node is at z=Z max,1 The plane with the lowest node coordinate (0,0,Z max,1 )

[0115] by Figure 5 Take the simulation model shown as an example, which satisfies the above |Z max,1 |<|Z min,1 |, therefore, the lowest node is at z = Z max,1 The plane with the lowest node coordinate (0,0,Z max,1 ), which is also the first contact point and rotation center of the virtual floor, the forward tilt angle Specific as Figure 7 shown.

[0116] The two values ​​Z obtained above are max,1 , Z min,1 , the relative position of the second lowest node in the entire simulation model is determined by the following two judgment formulas:

[0117] Z max,1 >0 and Z min,1 >0: The second lowest node is at the rear foot pad

[0118] Z max,1 <0 and Z min,1 <0: The second lowest node is at the front foot pad

[0119] by Figure 5 Take the simulation model of 2000 as an example, which satisfies the Z in the above judgment formula. max,1 <0 and Z min,1 <0, so the second lowest node is at the front foot pad. In this application, the constant Z is given α To define the search range of the front and back directions, take a laptop as an example, given Z α = 0, a virtual cube is created to search for all the nodes of the parts. The virtual cube consists of six planes, namely z = Z′ max 、z=Z a =0, x = X′ max , x=X′ min ,y=0,y=Ym ' ax , such as Figure 8 shown.

[0124] Specifically, a virtual cube is constructed based on the third vertical coordinate, the preset vertical coordinate, the third horizontal coordinate, the fourth horizontal coordinate, the preset vertical coordinate, and the third vertical coordinate. Then, based on the obtained virtual cube, the minimum cube surrounding the search node is obtained again, and the eight point coordinates of the minimum cube can be obtained respectively. The eight point coordinates can be expressed by six numerical values ​​X″ max , Y″ max , Z″ max , X″ min , Y″ min , Z″ min Indicates that the Y coordinate Y″ of the second lowest node can be obtained min , such as Fig. 9 shown.

[0125] S105, constructing a fifth cube based on the fourth data set of the fourth cube;

[0129] A fifth cube is constructed based on all the searched second nodes.

[0130] Specifically, it is known that the second lowest node is at y=Y″ min plane, it is necessary to establish a y=Y″ in the simulation model min A virtual plane is formed, and nodes of all parts are searched based on the virtual plane, and y=Y″ minThe virtual plane consists of four straight lines, namely z=Z″ max 、z=Z″ min 、x=X″ max 、x=X″ min , where the virtual plane is Fig.10 shown.

[0131] The fifth data set includes a ninth horizontal coordinate, a tenth horizontal coordinate, a ninth vertical coordinate, a tenth vertical coordinate, a ninth vertical coordinate, and a tenth vertical coordinate.

[0132] Specifically, the search node obtained on the established virtual plane is used to obtain the smallest cube surrounding the search node, that is, the fifth cube. The fifth cube has eight point coordinates, which can be expressed as six values ​​X max,2 , Y max,2 , Z max,2 , X min,2 , Y min,2 , Z min,2 express.

[0134] In some embodiments, determining the forward tilt angle of the second lowest node coordinate based on the fifth data set of the fifth cube includes:

[0135] Determine a seventh vertical axis coordinate value and an eighth vertical axis coordinate value in the fifth data set;

[0136] The seventh vertical axis coordinate value and the eighth vertical axis coordinate value are judged according to the third judgment condition, and the plane where the second lowest node is located and the coordinates of the second lowest node are determined according to the judgment result, and the forward tilt angle of the second lowest node is determined;

[0137] The lowest node coordinates and the forward tilt angle of the second lowest node are used as the target coordinates and the target forward tilt angle.

[0138] Specifically, the seventh vertical axis coordinate value and the eighth vertical axis coordinate value in the fifth data set are Z max,1 , Z min,1 , the two values ​​Z max,1 , Z min,1 Take the absolute value to compare the size, and use the following method to determine which z plane the second lowest node is located on:

[0140] =Z max,2 The plane with the second lowest node coordinate (0,Ymin,2 ,Z max,2 )

[0141] |Z max,2 |<|Z min,2 |∶The second lowest node is in z

[0143] by Figure 5 Take the simulation model in as an example and determine whether it satisfies |Z max,2 |>|Z min,2 |, so the second lowest node is at z=Z max,2 The plane with the second lowest node coordinates is (0,Y min,2 ,Z max,2 ), which is also the second contact point of the virtual floor, and calculates the forward tilt angle Where Y2 = Y min,2 ,Z1=Z max,2 , such as Fig.11 shown.
