【摘要】 文章针对空间网格结构形式多样、施工过程复杂、现场实践教学困难等问题,基于Unity3D虚拟现实开发引擎,融合BIM信息技术,设计并研发了一套装配式空间网格结构虚拟实验教学平台,涵盖结构形式、节点构造和施工方法三大实验模块。完成了典型空间网格结构建模、节点制作拼装、高空散装等多种施工方法的动态虚拟仿真、人机交互、知识点讲解等实验内容。基于该平台的实验教学弥补了现场实践教学的不足,提升了学生的工程实践能力和创新能力。更多还原

【Abstract】 Aiming at the three issues of various forms, complex construction process, and difficulty of on-site practical teaching, a teaching platform of virtual experiment for assembled spatial grid structures has been designed and developed, based on the Unity3 D and BIM technology. The developed platform contains three experimental modules: structural form, nodal structure, and construction method. The main functions of the platform consist of dynamic virtual simulation, human-computer interaction, and knowledge explanation in several aspects, including structural modeling, node assembly, and structural construction. Experimental teaching based on this platform makes up for the shortcomings of on-site practical teaching, and enhances the abilities of engineering practice and innovation of students.更多还原
