脱冰冲击下典型金具——耐张联板的力学特性分析
Study on Mechanical Properties of Typical Hardware-strain Coupler Plate Under Deicing Impact
摘要
Abstract
Regarding the study on the mechanical characteristics of the tension connecting plate under deicing impact and the optimization of the structure of the tension connecting plate,the existing study mainly focuses on the stress distribution of the tension connecting plate at a single time node,ignoring the issue of stress changes in the tension connecting plate throughout the entire time period.The present study establishes a finite element model for iced conductors and calculates the dynamic characteristics of 100%deicing under hazardous conditions.And a complete finite element model for hardware string was established,considering the supporting hardware such as tension connecting plates,and the mechanical properties tests of the hardware string under impact load were conducted.Based on the present model,the mechanical characteristics of the tensile connecting plate and supporting hardware under deicing impact were analyzed.It has found that a single time node stress cloud map of the tension joint plate cannot accurately distinguish the stress distribution in various regions of the tension joint plate.Under a single time node,the stress distribution of the tension joint plate has a certain gap with the stress distribution in various regions of the tension joint plate throughout the entire time period.The research results provide a more accurate reference basis for the study of mechanical properties and structural optimization design of tension connecting plates.关键词
