Abstract
Aiming at the structural characteristics of different parts of decelerator, the general rules of 3D part modeling was summarized, three-dimensional model of gear bracket was established, all marshaled parts were generated into the whole parts assembly, added a variety of assembly relation and hierarchical relation to the parts. Then the reducer assembly path was sketched out, assembly sequence of parts was determinated, the final completion of assembly simulation was finished. Virtual assembly technology is conducive to the rapid introduction of technology of advanced design method, improve product quality, reduce the cost of development, and shorten the development cycle, which lays the foundation of practical disassembly and assembly parts.
Highlights
Virtual assembly refers to computer aided design technology that helps to make better design decisions related to assembly during the process of product design and to conduct assembling analysis on the computer data model in a virtual environment
Similar to computational realization in a real process, virtual assembly technology conducts modeling and simulation through computers, being able to inspect coordination and ability to be assembled among the components, to ensure the correctness of the design, to reduce the burdens of design rework, to shorten the development time and to save the manufacturing cost of prototypes [3]
Based on the wide use of three dimensional CAD and the advantage of virtual assembly technology, this paper introduces a computer aided assembly process plan system based on virtual technology from the angle of the entire process of three dimensional product data in machinery assembly design and investigates the system structure, realization method and key techniques
Summary
Virtual assembly refers to computer aided design technology that helps to make better design decisions related to assembly during the process of product design and to conduct assembling analysis on the computer data model in a virtual environment. It combines virtual reality technology, advanced visualization technology, simulation techniques, decision-making theory, assembling and manufacturing techniques, etc. Similar to computational realization in a real process, virtual assembly technology conducts modeling and simulation through computers, being able to inspect coordination and ability to be assembled among the components, to ensure the correctness of the design, to reduce the burdens of design rework, to shorten the development time and to save the manufacturing cost of prototypes [3].
