特高压酒杯塔组立过程中的结构强度分析
摘要
Abstract
Due to the special structure of the ultra-high voltage large span wine glass tower,there is a great safety risk during its construction and assembly process,and it is necessary to calculate and verify the strength of the tower structure.This paper takes a certain ultra-high voltage large span wine glass tower as an example,and focuses on the assembly process of the tower head.A typical iron tower assembly state is selected,and finite element method is used to verify and calculate its strength.The stress and displacement distribution law of the iron tower structure is obtained.The results show that after adding diagonal braces,the structural strength of the tower assembly in states one,two,and three meets the requirements.For the assembly status three of the iron tower,in order to facilitate the installation and fastening of the components at the middle connection position of the cross arm of the iron tower,it is necessary to add a pulling wire between the two curved arms,and adjust the pulling force of the pulling wire to 16.3 kN,thereby reducing the distance between the middle connection position of the cross arm of the iron tower to 2 mm.The research conclusions of this paper can provide a reference for the formulation of a scientific and reasonable tower construction plan and ensure that the construction of UHV transmission tower can be carried out safely and efficiently.关键词
