摘要
近年来对结构的损伤分析方法甚多,本文利用ANSYS有限元软件对塔架结构的损伤进行数值模拟分析,基于结构损伤前后的振型数据,实现了对一平面塔架结构的较精确的损伤状态评估。数值模拟结果表明对塔架结构的损伤评估具有一定现实意义。
In recent years,there are many methods in order to analyze damage of tower truss structure.This paper is about to use ANSYS finite element software to analyze the numerical simulation of structure damage based on the data of damage structure and whole structure in order to fulfill the accurate evaluation of the damaged plane tower truss structure state.Results of the numerical simulation show some realism meaning to the evaluation of the tower truss structure damage state.
