城市轨道交通站台门参数化三维建模软件开发与应用

随着城市轨道交通飞速发展,站台门得到广泛运用,其设计工作量以及业主对站台门BIM(建筑信息模型)设计需求与日俱增。为了提高设计质量与效率,研究站台门系统结构组成、安装设计工艺与模型特征参数,利用遍历命名技术与基于模型特征化的三维设计技术,开发了站台门参数化三维建模软件。实现了站台门参数化建模和自动装配,提供了可视化模型,并在5 min内响应设计方案,为站台门BIM设计打下基础。

Development and Application of 3D Parametric Modeling Software for Urban Rail Transit Platform Screen Door System

With the rapid development of urban rail transit,the platform screen door system has been widely used,requirements for the design workload and BIM (building information modeling)design of the platform screen door have increased.In order to improve the design quality and efficiency,the system structure,process of installation and design,model parameters of the platform screen door are analyzed.By using the traversal naming technique and 3D design technology based on the model features,a 3D parametric modeling software for the platform screen door is developed.The software helps to achieve the platform door parametric modeling with automated assembly,provides a visual model which responses to the design in only 5 minutes,thus laying a solid foundation for the BIM design of platform screen door system.
