摘　　要：BIM技术逐渐应用于接触网的工程设计中,在实现精确的细部设计同时,也对相关计算提出了更高的要求。本文通过将接触网零部件参数化,建立全局坐标,引入空间向量概念,根据定位器的受力情况计算得出任意区段内所有悬挂点处定位器坡度,进而再根据具体安装形式计算得到悬挂装置零部件长度及空间位置等信息,实现BIM模型设计。利用该方法,打通了接触网安装与腕臂预配计算间的信息流,提高了BIM模型的设计精度,实现了平面布置图和安装图的统一。BIM technology has been gradually applied to the engineering design of OCS. While realizing accurate detailed design, it also puts forward higher requirements for relevant calculation. The paper parameterizes the OCS fittings and parts, establishes the global coordinates, introduces the concept of spatial vector, calculates the slope of steady arm at all support points in any section according to the stress of the steady arm, and then calculates the length and spatial position of the fittings and parts of support device according to the specific type of installation, so as to realize the design of BIM model. By using this method, the information flow between OCS installation and calculation of cantilever pre-assembling has been opened up, the design accuracy of BIM model is improved, and the unification of layout and installation drawing is realized.
