Abstract

The invention discloses a natural interactive virtual assembly system based on a full semantic product model in the manufacturing field. In the invention, an interactive generation module of the full semantic product model executes the extraction of product information from a CAD assembly model of a product to interactively generate the full semantic product model; an assembly data preprocessing module processes a collision model of parts of the product and establishes the corresponding relation among a display model, the collision model and the full semantic product model; a virtual assembly simulation module drives virtual hands in a driving virtual environment by utilizing a VR interactive perpheral to realize the interactive virtual assembly between two hands and tool utilization; a full semantic product model processing module is mainly responsible for the detection as well as the recognition and resolution of the constraint of each model of the full semantic product model; and an assembly tool management module imports a tool selected by a user into the virtual environment of the virtual assembly simulation module and processes the driving of the tool at any time. The natural interactive virtual assembly system increases the authenticity and the sense of immersion of virtual assembly, and can provide powerful support for the planning and analysis of assembly technology.

Description

technical field [0001] The invention relates to a simulation system in the field of manufacturing, in particular to a natural interactive virtual assembly system based on a full semantic model of a product. Background technique [0002] Assembly is a key step in the process of product design and realization. Interactive virtual assembly based on virtual reality technology can realize close to real product assembly in a virtual environment, and can perform assembly verification, assembly efficiency calculation, assembly process planning, assembly line design, and ergonomics evaluation on this basis. The use of interactive virtual assembly system in the process of product development is of great significance to reduce repetitive labor, reduce development cost, and shorten development cycle. In the interactive virtual assembly system, the more natural and closer the interactive operation is to the actual operation, the closer the virtual assembly is to the real assembly, and t...
