The system comprises a pattern groove design module, a pattern groove intersection design module, a decoration design module and an auxiliary modeling module; the pattern groove design module comprises a first layer pattern groove design unit, a second layer pattern groove design unit, a third layer pattern groove design unit, a multi-segment pattern groove design unit and a tire should pattern groove design unit; the pattern groove intersection design module comprises an X type intersection processing unit, a T type intersection processing unit and a V type intersection processing unit; the decoration design module comprises a steel sheet characterization design unit, a groove bottom boss characterization design unit, a groove bottom rib characterization design unit, a new tire identification line characterization design unit, an attrition mark characterization design unit and a steel sheet intersection processing unit; and the auxiliary modeling module comprises an automatic assembly unit. The system disclosed by the invention can regulate the design flows of the tire patterns and improve the tire design efficiency and quality.

Description

technical field [0001] The invention belongs to the technical field of the tire industry, and relates to a tire pattern parameterized design system and a method thereof. Background technique [0002] At present, most tire companies use common CAD software such as CAXA, AutoCAD, CATIA, and UG to manually draw tire 2D and 3D patterns. However, due to the complexity of the tire pattern structure, the traditional two-dimensional CAD design method cannot accurately and intuitively express the complete information of the pattern, and although the large-scale general-purpose three-dimensional CAD software is powerful, it has problems such as low specificity, which forces users to do more in the pattern design process. Approximation processing and a large number of manual repeated operations are used in the process, which seriously affects the design efficiency and quality. Judging from the design results, most of the general-purpose CAD drawing software designs based on points, li...

AI Technical Summary

Problems solved by technology

[0003] I. In the process of surface modeling, designers need to perform a lot of repeated operations, which is inefficient;

[0004] II. Modeling takes the curved surface as the smallest design unit, and the degree of differentiation is not large. The design methods of different designers cannot be unified, and the design process is not standardized, which affects the standardized management of enterprises;

[0005] III. Lack of semantic expression and processing. The traditional CAD system only records the design results of the designer, but cannot express the user's design intention, causing difficulties for the user to understand the design, etc.;

[0006] IV. It is not conducive to the follow-up expansion design of tire pattern design, such as the establishment of pattern analysis model and further optimization and improvement, etc.
