基于BIM的接触网腕臂装配设计系统研究

BIM based catenary cantilever assembly design system

针对现阶段接触网腕臂装配建筑信息模型(BIM,Building Information Modeling)设计主要采用通用安装模型,无法精确反映现场实际安装情况的问题,建立单元库创建腕臂装配模板,结合参数化单元技术及自定义实体等技术,研发了基于BIM的接触网腕臂装配设计系统。该系统可快速创建并布置接触网腕臂装配模型,实现装配设计的自动化和智能化。实践表明,开发的系统大幅提高了接触网腕臂的装配质量和精度,可满足接触网BIM设计的需要,为进一步推进接触网的数字化、智能化发展提供支撑。

At present,the design of the Building Information Modeling(BIM)for catenary cantilever assembly mainly adopts a universal installation model,which cannot accurately reflect the actual installation situation on site.This paper established a unit library to create a cantilever assembly template,and combined parameterized unit technology and custom entity technology to develop a BIM based catenary cantilever assemblydesign system.This system can quickly create and arrange a catenary cantilever assembly model,achieving automation and intelligence in assembly design.Practice has shown that the developed system has significantly improved the assembly quality and accuracy of the catenary cantilever model,which can meet the needs of the BIM design of the catenary and provide support for further promoting the digital and intelligent development of the catenary.
