摘　　要：疲劳载荷谱是结构零部件疲劳设计、疲劳寿命预估、模拟实验、强度分析与计算以及可靠性设计的依据,也是经处理后获得的载荷–时间历程。本文在相关文献的基础上,通过对网架结构模型的瞬态分析,考虑网架更全面的实际工况和影响因素,得到悬挂吊点的载荷–时间历程,并对平板网架结构疲劳载荷谱编制的相关问题进行了探讨。Fatigue load spectrum is the basis of fatigue design,fatigue life prediction,simulation experiment,strength analysis and calculation and reliability design of structural components.It is also the load-time history obtained after treatment.Based on the transient analysis of the grid structure model,the load-time history of suspended suspension points is obtained.Some problems related to the compilation of fatigue load spectrum of flat grid structures are also discussed.
