2) steel antenna
钢质天线
1.
The power spectra of the stress responses at critical points of a steel antenna are obtained with a wind tunnel test on its aerodynamic full model.
根据一屋顶钢质天线结构气弹模型风洞试验结果,计算了疲劳分析关键点处的应力响应功率谱;基于疲劳累积损伤理论在频域上用等效窄带法对钢天线进行寿命估算;同时,根据关键点处的应力响应功率谱,用Monte Carlo方法模拟了应力时程响应,并用雨流法对应力时程响应进行计数,用Goodm an法则考虑平均应力的影响后得到应力范围出现的概率,然后拟合了应力范围的概率密度函数,对天线进行寿命估计。
