摘要/Abstract

摘要： 使用Unity3D软件开发基于Microsoft HoloLens的UWP(Universal Windows Platform)有限元分析结果虚拟评审应用。利用Matlab进行编程完成三维实体静力有限元分析。为实现变形效果的可视化,提取有限元分析结果,生成VTK(Visualization Toolkit)格式文件,利用自制的文件转换器转换成.dae文件。在Unity3D软件中编写顶点着色器脚本实现片面模型的颜色显示和变形效果的可视化,最终发布UWP应用。实验结果表明：Matlab和Ansys Workbench有限元分析结果相吻合,基于HoloLens的有限元分析变形结果虚拟评审应用沉浸感强,交互性高,并可以推广到其他有限元分析应用领域。

Abstract: An UWP application of virtual review of the finite element analysis based on Microsoft HoloLens is developed by using Unity3D software. A set of programs are completed to realize three-dimensional solid static finite element analysis in Matlab. To realize the visualization of the deformation effect, the useful information of the finite element analysis result is extracted and exported to VTK file, then converted into DAE file. A vertex shader is written in Unity3D software to realize the color display and the visualization of deformation effect of one-sided model, and finally the UWP application is released to HoloLens. The test results show that the finite element analysis results of Matlab and Ansys Workbench are consistent. The virtual review application of the finite element analysis deformation results based on HoloLens has strong immersion and high interactivity, and can be extended to other application fields of finite element analysis.

Key words: Unity3D, Microsoft HoloLens, finite element, virtual review, Matlab, VTK(Visualization Toolkit)
