通信单管塔加挂LED广告牌有限元分析

Numerical Simulation of the LED Billboard Loaded with Communication Monopole

通信单管塔加挂LED广告牌需要对塔身进行有限元建模分析,而广告牌的尺寸、重量、透风率、挂高等因素均影响复核结果。文章利用有限元分析软件SAP2000建立单管塔模型,对比加挂LED广告牌前后的自振周期、塔顶位移、塔身最大应力及塔脚倾覆弯矩等参数,通过列举计算法得到最优的广告牌参数,从而达到最优经济效应。

The communication monopole with LED billboard needs finite element modeling and analysis,the size,weight,ventilation rate,hanging height of the billboard affect the results of the review.In this paper,the finite element analysis software SAP2000 is used to establish a monopole tower model.The parameters of natural vibration period,tower top displacement,maximum stress of tower body and tower bottom overturning moment before and after adding LED billboards are compared,and the optimal billboard parameters are obtained by enumerating calculation methods,so as to achieve the optimal economic effect.
