基于Unity的模型虚拟装配系统研究
|
摘要
为了改善Pro/E等软件进行零件装配不够直观,以及仅面向单个产品的虚拟装配系统花费成本高且适用性低的问题,本文将虚拟装配技术用于工业产品设计与制造的过程,实现了产品装配过程可视化,具有即导即用的特点,缩短了产品设计周期。使用Unity引擎,以及HTC Vive头盔式显示器,进行模型的组装与拆卸系统的设计与研究,提出了多零件模型在虚拟环境中定位与复位的实现方法,初步实现虚拟装配过程。实验结果表明:模型导入即可使用,并可在虚拟环境下进行基本组装与拆卸操作。
As the part assembly process with the software,like Pro/E,is not intuitive enough and the single-productoriented virtual assembly system costs too much with low applicability,this paper adopts the virtual assembly technology in industrial product design and manufacturing process to achieve the visualization of the assembly process,with the characteristics of model import and use,shortening the product design cycle.Conducting the design and research of the assembly and disassembly of the model with the Unity engine and the Head Mounted Display(HMD) of HTC Vive,the paper proposes the method of locating and resetting the multi-parts model in the virtual environment,and the virtual assembly process is initially achieved.The experiments show that the virtual model can be imported into the system,and be assembled and disassembled in the virtual environment.
