Elastic modulus sensitivity analysis method and system for power transmission tower-platform system

Abstract

The invention discloses an elastic modulus sensitivity analysis method and system for a power transmission tower-platform system. The method comprises the following steps: acquiring power transmissiontower node information and unmanned aerial vehicle platform information; determining elastic modulus and load parameters of the power transmission tower-platform system; respectively calculating theparameter sensitivity of the unmanned aerial vehicle platform supporting component, the parameter sensitivity of the unmanned aerial vehicle platform component and the parameter sensitivity of the transmission tower component; summing the parameter sensitivity of the unmanned aerial vehicle platform supporting component, the parameter sensitivity of the unmanned aerial vehicle platform component and the parameter sensitivity of the power transmission tower component, and calculating the elastic modulus sensitivity of the power transmission tower-platform system; and calculating the frequency change of the power transmission tower-platform system based on the elastic modulus sensitivity and the elastic modulus change of the power transmission tower-platform system. The analysis method fillsthe blank of lack of a sensitivity analysis method for the unmanned aerial vehicle platform of the power transmission line at present, and can be effectively applied to sensitivity analysis and calculation of the unmanned aerial vehicle platform of the actual power transmission line.

Description

technical field [0001] The invention relates to a transmission line safety assessment technology, in particular to a method and system for analyzing the elastic modulus sensitivity of a transmission tower-tower system. Background technique [0002] Transmission line is an important lifeline project, which has served in the harsh environment of the field for a long time, and is subjected to wind, sun and various environmental effects. Therefore, transmission lines are prone to damage accumulation and failure during long-term service. In recent years, there have been many reports of damage and damage to transmission lines at home and abroad, resulting in serious economic losses and secondary disasters. Therefore, a lot of transmission line defect inspection and research and development of equipment have been carried out at home and abroad. Since the transmission tower is a high-flexible structure, its defect inspection work is usually carried out manually, but the manual ins...
