摘要
支柱装配调整计算是电气化铁路接触网新建、改造施工和运营维护作业中的一个重要的计算项目。本文 以接触网支柱装配计算原理为基础,建立了接触网支柱装配调整计算的数学模型。在对数学模型进行数学变换 和数学分析的基础上,得出了适用于作业现场计算的简化算式。实践应用和对比计算证明,采用数学模型计算, 结果精确,适用于计算机编程计算;采用简化算式计算,方法简单,适用于在施工现场进行手工计算;这两种方 法均能满足支柱装配调整施工一次到位的要求。
The adjustment calculation of catenary post assembly is an important calculation item in construction, innovation and maintenance of catenary of electrified railway. The mathematics model for adjustment calculation of catenary post assembly is established in this paper based on the calculation principle for catenary post assembly. The suitable simplified calculation formula for calculation at working site is presented on the basis of making mathematical transformation and analysis to the mathematics model. It is proven by the practice and comparison calculation that calculation made by mathematics model is suitable for computer programming calculation with high accuracy result and calculation made by simplified calculation formula is easy and suitable for manual calculation at working site. These two methods can meet the requirements of making adjustment into place one time for post assembly.
