Engine modeling method based on behavior flow complex product function community and evolving of behavior flow complex product function community

Abstract

The invention provides an engine modeling method based on a behavior flow complex product function community and evolving of the behavior flow complex product function community. The method comprises the following steps that a behavior is used for defining an initial state and a target state of a product, an appropriate behavior changing sequence achieving the state change is obtained based on the two states, and accordingly a behavior flow model in the product designing process is established; an initial mapping relation between the behavior and a function is obtained; an engine functional community and evolving model based on the behavior flow is established. An emphasis is made on carrying out the intensive study on the expression problem of the behavior flow, the behavior flow space sequence which is a brand new concept is provided in the study, the intelligent product design process based on the behavior flow is described from the angle of the space sequence evolving change, and two behavior space sequence expression modes and a conversion principle of the two expression modes are provided.

Description

technical field [0001] The invention relates to an engine modeling method in the field of product modeling based on a complex product functional group of behavior flow and its evolution. Background technique [0002] Complex products refer to a class of products with complex structures, intensive technology, high manufacturing requirements and costs, complex process management, and changing customer needs. The conceptual design is the core stage of the complex product design process and the fundamental link to enhance product competitiveness. Statistics show that the conceptual design stage, which accounts for only 5% of the cost, determines 85% of the product life cycle cost, and more than 70% of the product design quality. Time and cost are the key factors that determine the success of a product just like quality. Since conceptual design is in the earliest stage of the product life cycle, it has a great influence on the subsequent design process. Conceptual design fundam...

They are one-sided from the point of view, and may only be applicable to some fields and are not universal. On the other hand, human knowledge and experience are actually looking for functional design.
