Aiming at fussy operations and expressions of design information scattered of 3Dtread patterns modeling,which caused by the way that dominated by geometric features,a semantic-driven3 D modeling approach was proposed herein.The structures of the groove features,ornament features and intersection features in the theoretical design were decomposed abstractly to obtain the semantic units of the tire pattern based on discussion and research on the application theory and practical technology of pattern design.Then,the hierarchical,systematic,formal expressions of tire tread pattern from conceptual design to assembly design were realized by the introduction to tire pitch information.Finally,feature-based modeling technology was introduced,making CATIA/CAA as the development platform to develop a semantic level 3Dtire patterns design system.The example analysis results show that the system is applicable to a variety of types of tire patterns modeling,enhancing the ability of the CAD technology design of information description and improving the automation level of product modeling,thus effectively reducing the repetitive work of designers and shortening the development cycle.
