Research on Optimization Process of Hierarchical Architecture for Virtual Prototype Based on User Experience

The key point of virtual product development in parallel engineering is to build the the model of virtual prototype, which is responsible to supply with various kinds of signal in a whole design cycle of a specified product; The construction method is a main direction of virtual product development and research. In this article, the research condition of virtual prototype is analyzed; and based on the analyzed result, the human-computer interaction theory and design methods, such as user experience, are applied to the modeling process of virtual prototype. A new flow chart of virtual prototype building process is raised. This flow chart first apply a five-layer analysis method to the key points of building model. In the process of optimization, the effective of building model and the operators’ efficiency are highly raised; and the period of the development of product has been shortly, which can satisfy the demand that the quick modeling of complex virtual prototype.
