Abstract: Aiming at the configurability, reusability and flexibility requirements of product structure in variant design, the semantic relationship between generic product structure and data was deeply analyzed. And a configurable product structure model combining extensible andor tree with assembly directional graph was proposed. Extensible andor tree was used to cover a group of variant product structures, and internal semantic relationships and configuration conditions among product nodes were set up to support variant of composite structure. Assembly directional graph was adopted to describe assembly relationships and directions to represent assembly semantics for product structure. Moreover, extensible property sets were used to describe properties and relationships of nodes in product structure, and to support parameter variant and transmission for variant products. Finally, this model was illustrated by a shock absorber product series to demonstrate its feasibility for rapid variant design.

Key words: variant design, configurable product structure, extensible andor tree, assembly directional graph, extensible property sets
