摘要
引入当量线密度的概念,采用力学计算的方法,针对弹性链形悬挂五跨式锚段关节过渡跨整体吊弦进行分析,由于过渡跨具有2个悬挂点,一个是弹性链形悬挂,另一个是简单链形悬挂,且接触线呈屋面布置结构的特殊性。因此本文详细论述了锚段关节过渡跨整体吊弦计算模型的建立及计算公式的推导过程。
By introducing the concept of equivalent line density and the adoption of force calculation to analyze the dropper assembly in transitional span in five span overlapping section of stitched chain suspension catenary; since there are two suspension points： one of which is of stitched chain suspension and the another is of simple chain suspension, and furthermore, the contact wire is being arranged in house profile configuration, so the paper illustrates in details the establishment of calculation model for dropper assembly in transitional span of overlapping section and the deduction of the calculation formula.
