[0051] Example 1

[0052] An embodiment of the present application provides a modeling method for a leaf spring.

[0053] See also Figure 1 , the modeling methods of leaf springs include:

[0054] S101, obtaining multiple spring parameters of a target leaf spring.

[0055] In this embodiment, the leaf spring is set according to the overall requirements of the vehicle, such as total mass, front and rear axle loads, wheelbase, offset frequency and ground clearance, and the set leaf spring is used as the target leaf spring, and various parameters of the target leaf spring are collected.

[0056] S102, respectively obtaining a plurality of curvature radius values ​​and a plurality of target angle values ​​according to the spring parameters.

[0057] In the embodiment of the present application, various parameters of the target leaf spring are collected by establishing an EXCEL table, the curvature radius value and the target angle value are calculated by the various parameters, and the curvature radius value and the target angle value are filled in the table, thereby completing the establishment of the table. In other embodiments, data collection can be performed through other documents that can record data, which is not limited in this application.

[0058] In one embodiment, the spring parameters include: a spring length value, a spring height value, and an arc height value; and a plurality of curvature radius values ​​are obtained according to each of the spring parameters, including:

[0059] The spring leaf length value, the spring height value and the arc height value of the first leaf spring are calculated according to the curvature radius calculation formula to obtain the curvature radius value of the first leaf spring, wherein the curvature radius calculation formula is:

[0060]

[0061] Wherein, R0 is the curvature radius value of the first leaf spring, L1 is the spring leaf length value of the first leaf spring, and H0 is the arc height value of the first leaf spring;

[0062] The curvature radius value of the i-th leaf spring is determined according to the spring parameters and the curvature radius value of the i-1th leaf spring, where i≥2.

[0063] Optionally, the sum of the spring thickness value and the curvature radius value of the (i-1)th sheet is determined as the curvature radius value of the i-th sheet.

[0064] It should be noted that the spring parameters also include the number of leaf springs that need to be modeled. For example, if a digital model of eight leaf springs needs to be established, the curvature radius value of the first leaf spring is calculated using the curvature radius calculation formula, and the curvature radius values ​​of the remaining second to eighth leaf springs are determined by the sum of the spring thickness value and the curvature radius value of the previous leaf spring.

[0065] It is further explained that the spring thickness values ​​of each leaf spring are equal, and the corresponding angle can be calculated by obtaining the curvature diameter, where the curvature diameter value is twice the curvature radius value.

[0066] In one embodiment, the curvature radius of the j-th leaf spring is calculated according to an angle calculation formula to obtain the target angle value of the j-th leaf spring, where j≥1;

[0067] The angle calculation formula is:

[0068]

[0069] Wherein, θ is the target angle of the j-th leaf spring, L j is the length of the spring leaf of the j-th leaf spring, and R0 is the radius of curvature of the j-th leaf spring.

[0070] It should be noted that the sketch is established in sequence according to the leaf spring parameter table based on the target angle value and curvature radius value of the leaf spring. For example, if the spring parameter setting has eight leaf springs, the initial sketch is established in sequence from the first leaf spring to the eighth leaf spring through the leaf spring parameter table.

[0071] In one implementation, the length value of the spring piece of the j-th piece is determined according to the length value of the spring piece of the j-1th piece and a preset suspension offset frequency.

[0072] It should be noted that the length of the spring leaf of the first leaf and the length of the spring leaf of the second leaf are set to the same length value, and the spring parameters also include: suspension mass and suspension frequency deviation. The leaf spring stiffness is calculated according to the formula, and then the leaf spring thickness and leaf spring width are estimated based on the leaf spring stiffness.

[0073] The calculation formula of leaf spring stiffness is:

[0074]

[0075] Among them, n is the suspension offset frequency, m is the suspension mass, and C is the leaf spring stiffness.

[0076] According to the main leaf spring length L and leaf spring thickness h, the length of each leaf spring is calculated using the drawing method. Specifically, the leaf spring length value, the suspension frequency deviation and the center distance of the leaf spring on the bridge housing are determined by the spring parameters, where the leaf spring length value is the length value of the first leaf spring. The ordinate in the drawing method is the cube of the spring thickness value, the abscissa is half of the length of the first leaf spring, and the length of the last horizontal line is half of the center distance of the leaf spring on the bridge housing. By connecting the end of the last line and the end of the second line, the horizontal length of the intersection of the horizontal line and the oblique line is half of the length of the corresponding leaf spring. The distance between the intersection and the ordinate is the length of the corresponding spring leaf.

[0077] S103, establishing a leaf spring parameter table according to the curvature radius values, the target angle values ​​and the spring parameters. Specifically, as shown in Table 1:

[0078] Table 1 Leaf spring parameters

[0079]

[0080]

[0081] S104, drawing a plurality of initial sketches in sequence according to the leaf spring parameter table, adjusting each of the initial sketches, and generating a target leaf spring model according to the adjusted target sketch.

[0082] In one embodiment, the spring parameters also include: a spring width value; drawing a plurality of initial sketches in sequence according to each of the curvature radius values ​​and each of the target angle values; adjusting each of the initial sketches in sequence according to the spring width value and the spring thickness value, and generating the target leaf spring model according to the adjusted plurality of target sketches.

[0083] Optionally, the leaf spring of each of the initial sketches is stretched according to the spring width value; the leaf spring of each of the initial sketches is thickened according to the spring thickness value; and the leaf spring of each of the initial sketches is rounded according to the spring thickness value.

[0084] In this embodiment, the conditioning is performed in the following steps in sequence: Figure 2 As shown in the figure, stretch the width of the initial sketch to the spring width value in the leaf spring parameter table, such as Figure 3 As shown in the figure, the initial sketch after stretching is thickened to the spring thickness value in the leaf spring parameter table, as shown in the figure. Figure 4 As shown in the figure, the initial sketch that has been thickened is rounded according to half the spring thickness value to finally obtain the target sketch.

[0085] It should be noted that according to the leaf number sequence of the leaf spring parameter table, the leaf spring is sketched and stretched, thickened, and rounded in sequence, and the digital modeling of multiple leaf springs is generated in sequence to generate the target leaf spring model. Figure 5 shown.

[0086] It is further explained that if the vehicle demand changes, resulting in changes in the leaf spring parameters, the leaf spring values ​​in the leaf spring parameter table will be adjusted.

[0087] For example: when the layout of the whole vehicle is difficult, if it is required to reduce the length of the leaf spring, then the length value of the leaf spring leaf should be reduced, and the remaining length value of the leaf spring leaf will change accordingly; when the total weight of the whole vehicle changes, the spring thickness value and spring width value in the leaf spring parameter table are adjusted; when the height of the whole vehicle from the ground changes, the spring curvature height value is adjusted.

[0088] If the value is adjusted, the curvature radius and target angle of each leaf spring need to be recalculated in the leaf spring parameter table. When the data in the leaf spring parameter table is updated, the digital model needs to be updated. In the initial sketch, the curvature radius and target angle values ​​are adjusted piece by piece according to the values ​​in the leaf spring parameter table. The digital model will be updated in time according to the parameters without the need to rebuild the model.

[0089] The modeling method of the leaf spring provided in this embodiment includes: obtaining multiple spring parameters of the target leaf spring; obtaining multiple curvature radius values ​​and multiple target angle values ​​according to each of the spring parameters; establishing a leaf spring parameter table according to each of the curvature radius values, each of the target angle values ​​and each of the spring parameters; drawing multiple initial sketches in sequence according to the leaf spring parameter table, and adjusting each of the initial sketches, and generating a target leaf spring model according to the adjusted target sketch. Through the provided scheme, the model of the leaf spring can be updated in time through parameters, saving time and energy consumed by remodeling, and further improving work efficiency.
