The Design And Implementation Of Engine Virtual Assembly System Base On Unity3D

With the development of technologies such as computer graphics， computersimulation, artificial intelligence, sensor technology, display technology, networkparallel computing, virtual reality has been developed in a great many of fields.Especially in some fields such as stabilized, have a mature production system, largevolume, high operational risk, expensive in using and maintenance, needs learningover and over, virtual reality technology has a large development space. Virtualreality technology has been extensively used in industrial development, scientificresearch, teaching, because of its convenience, reality, interactive, benefits, reusability.And then like virtual manufacturing, virtual medicine, virtual assembly has raised.Automobile engine virtual assembly confirm to the advantages of virtual realityjust in time. The article is about automobile assembly course teaching case of avocational college, and combines with the process of automobile assembly,3Dmodeling technology,3D interactive design theory, theory of programming, virtualreality technology, basing on Unity3D and carry through theoretical discussion anddevelopment practice of virtual assembly, and finally designed and realized the “THEDESIGN AND IMPLEMENTATION OF ENGINE VIRTUAL ASSEMBLYSYSTEM BASE ON UNITY3D”. Through practical application, the design realizedthe following points: the process of engine assembly has been reduced the dependenceof real engine, solved the problem of shortage of experiment equipment and trainingplaces, and less teacher or assistant, and low experienced in operation causing damageof equipment or accident. Making the students can train virtually in every time, everyplace, and every choice. And they can make self-evaluating.
