The Feature Generation Of Automobile Form In Interactive System

As a part of the"973"research project on Special Knowledge of Industrial Product Form Design and Computer Aided Design System,this paper discusses the framework of automobile form features, design process and form features generation in interactive system.Using the form feature theories, this paper analyzes the cognitive model of design,the concept generation and the interactive processes in terms of automobile form design. The purpose of this research is to find out how form features are generated in automobile design processes,and how to build an interaction system. Based on the design theories research and their applications,the paper provides a new design method for automobile form design with an interactive approach.By using cognitive psychology,form feature's representation method,task analysis and computer agent technology,this paper analyzes the design process and the capturing and representation of the basic features of automobile form,and establishes the tree framework of the automobile form features.Then the paper compares the cases in the non-interactive system with the one in the interactive system,and researches the process of evolutionary generation of features in hand sketching and CAD. A cognition model of features generation in the interactive system is proposed. Finally this paper also introduces dynamic link mechanism,role-play and Case-Based Design into the model,and uses DARIS computer agent technology to build this model.
