Assembly Process Modeling Based on Hierarchical Tree

Abstract

Assembly process has a complicated influence on dynamic characteristics and the product performance. However, the information model of the non-geometric process parameters isn’t considered by the existing assembly modeling methods. Based on the further developing of the traditional hierarchical structure, the assembly process layer hierarchical structure was obtained. By acquiring the assembly feature constraints hierarchy tree in Pro/E, and re-modeling the hierarchy tree information, a model of the assembly process hierarchy tree was proposed, and its information model was established. The software instance showed the application of the assembly modeling method. Computer aided alignment showed the proposed approach superior in the assembly process planning, managing and tracking. By the key assembly parameters information modeling, data for subsequent product alignment analysis was supported.
