Detailed Description
The technical features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1, the invention relates to a method for automatically arranging studs in a tread pattern of a tire, which comprises the following steps:
s1) generating a plurality of product files with pattern pitch patterns of the positions where the studs are placed through CATIA software, and generating the product files with pattern development patterns of the whole circumference of the tire; making standardized naming for the points of the embedded nail arrangement positions in a product file of the pattern pitch pattern with the embedded nail arrangement positions;
s2) generating an embedded nail placing position configuration table, and arranging embedded nails of specific patterns at the marked positions according to the embedded nail placing position configuration table;
s3), obtaining the coordinates of all the embedded nails after the embedded nails are placed; sequentially starting to calculate the total number of the embedded nails within a certain range by using the first embedded nail in the starting direction, and outputting the calculated total number; comparing the total number with a regulation rule, judging and outputting a judgment result;
s4), in the step S3), the output judgment result does not exceed the regulation, and the setting position configuration table of the embedded nails in the step S2) is used as the final embedded nail appointed position sequencing configuration table;
in step S3), the output determination result exceeds the regulation, and then the process returns to step S2), after the setting position configuration table of the insert nails in step S2) is modified, the process from step S2) to step S3) is repeated until the determination result does not exceed the regulation.
Step S1) is specifically performed: an engineer firstly draws a single pattern pitch with a nail setting position point through CATIA software; the position points needing to be embedded with nails are subjected to standard naming, the naming mode is different from that of the CATIA software native function point, as shown in FIG. 2, the position points needing to be embedded with nails in a single pattern pitch are named as PT1, and PT2.
And expanding the designed single pattern pitch file with the embedded nail placing position points into a file with a plurality of pattern pitches with the embedded nail placing position points through an expansion rule of pattern pitch design. When the laws and regulations are met, the positions for placing the embedded nails in other expanded pattern pitches may be different on the premise that engineers guarantee even distribution during design as much as possible.
The generated pattern pitch files need to be assembled through a product module of the CATIA, a plurality of generated pattern pitch files with embedded nail arrangement position points are loaded in the product environment of the CATIA, the files are arranged into a pattern development picture of the whole circumference of the tire according to the arrangement sequence of patterns through a certain constraint relation, and the product files with the patterns arranged in a whole circle are generated.
The Constraint relationship here refers to a "Coincidence Constraint" command in a CATIA Assembly (product) environment, i.e., a coaxial Constraint command. All pattern pitch patterns can be manually constrained to be arranged in the pitch arrangement order. This is a small function based on the CATIA assembly (product) environment, and the designer can realize automatic arrangement of the graphics by only inputting the pitch arrangement order.
Step S2), after the product file in which the patterns are arranged in a complete circle is completed in step S1). Under the product design environment of CATIA, a designer operates software to enable a program to traverse file names of a product structure tree, and sequentially captures the sequence of the file names on the structure tree into a table according to the format of a configuration table, wherein the sequence is the sequence according to the pattern pitch. And simultaneously, the program traverses the names of the points of the positions where the studs are placed in all the files in the product structure tree and places the names of the points PT1, PT2.
The designer confirms at which points on the pitch the nails are placed and marks them, and can confirm them after completion. And calling the nail embedding template by the program and placing the nail embedding graph on the marked position point in the table according to the nail embedding arrangement position configuration table. As shown in fig. 3, the snowy tire exemplified in fig. 3 is composed of 20 pitches, each pitch being denoted by P1. The placement points of the studs on each pitch, denoted PT1 through PT4, are driven by the configuration table of stud placement positions to place the stud pattern directly on the desired placement point on each pitch.
It should be noted that the positions and the number of the studs placed at each pitch are related to the pitch of the pattern and the requirements of the laws and regulations, so that the number of the studs placed at each pitch is not necessarily the same, and the positions of the studs are not necessarily the same.
Step S3), after finishing the step S2), all the stud patterns are placed. And acquiring the coordinates of all the embedded nails (or the embedded nail placing points) through a program. Sorting is performed with the origin of the SAE coordinate system of the tire as a starting point and the Y forward direction in the direction of the origin as a starting direction. And sequentially calculating the total quantity of the embedded nails in a certain range by the first embedded nail and outputting.
For example, the assembly drawing of the assembled embedded nail shown in fig. 4 is that the total number of embedded nails per 1 meter is calculated by starting with nail 1, then the total number of embedded nails per 1 meter is calculated by starting with nail 2, then the total number of embedded nails per 1 meter is calculated by starting with nail 3, and then the total number of embedded nails per 1 meter is calculated by starting with nail 4, so that the total number of embedded nails per 1 meter is calculated by starting with each embedded nail in turn, and finally the maximum number of embedded nails calculated by which embedded nail is output, that is, the maximum number of embedded nails is output.
And comparing the result with a rule and judging to see whether the nail embedding sequence configuration table needs to be adjusted or not. If the position of the embedded nail needs to be adjusted, a designer needs to automatically acquire the information of the current embedded nail arrangement and pop up the information of the configuration table through a program again, the position of the embedded nail needing to be changed is adjusted in the acquired information of the current embedded nail arrangement and the pop-up configuration table, and after the position adjustment is confirmed, the program can automatically refresh and generate the latest graph.
And (4) continuing the processes from the step S2) to the step S3) on the basis of the generated latest graphic file until the generated graphic meets the design requirements of the laws and regulations, and finishing the stud arrangement design.
The process does not need to generate a pitch and pattern combination model with different nail embedding quantities in advance, an output model is generated in a combination assembly mode, and meanwhile, the arrangement of the nails embedded in the array can be quickly adjusted and refreshed in a configuration table mode, so that the design process of a designer is simplified.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
