Problems solved by technology

[0004] In the existing finite element analysis methods of transmission towers, most of them use ABAQUS and ANSYS software for analysis, and because of this kind of simulation work, it is not suitable for the flow between different working groups of the project, and it is often necessary to modify a simple parameter. It is necessary to re-modify the simulation by the simulation engineer, and the simulation program is easy to modify, which increases the cumbersomeness among the project working groups

Abstract

The invention discloses a power transmission tower structural mechanical analysis and App (Application) establishment method which comprises the following steps: on the basis of COMSOL Multiphysics software, modeling according to a structure of a power transmission tower and a cross section and a material of a rod, applying external loads such as self weights, wind and ice loads of power transmission towers, leads and insulators, performing stress analysis on the power transmission tower, and generating stress cloud atlas, deformation cloud atlas and result reports; secondly, through an App developer inside the software, designing an App of power transmission tower structure stress analysis by using a form editor and a method editor. The method can be widely applied to finite element modeling and structure stress analysis on a power transmission tower, and by using the App established simultaneously, non-professional operators without skills of finite element modeling and simulation analysis can be enabled to obtain calculation results by rapidly modifying parameters of models.

Description

technical field [0001] The invention relates to the technical field of structural mechanics analysis of transmission towers, in particular to a method for structural mechanics analysis of transmission towers and software production based on COMSOLMultiphysics software. Background technique [0002] Transmission towers are large steel structures that support overhead transmission lines and ground wires to keep a safe distance from the ground, and play an important role in the safety and stability of power systems. Since the transmission tower is exposed to the outdoors, it is easily affected by the outside weather. In recent years, with severe changes in the global climate, various extreme natural disasters have occurred frequently, and disaster events have also seriously affected the power system, such as the super typhoon "Dawei" in 2005 and the ice disaster in southern China in 2008. The stable operation of the power system is the lifeblood of the national economy. The s...
