摘　　要：应用名义应力应变法 ,以弹簧质量系统的瞬态响应和稳态响应为数据 ,对其静强度可靠性和疲劳寿命进行了估算 .提出了如S -N曲线的获得、应力谱的等效的具体办法 。This paper makes the computation to the static intension reliability and fatigue work-life of spring mass system by means of nominated stress srtain method based on the data of the instantaneous response and stable reaction.Presents some practical and efficient ways as the formation of S-N curve and the cquivalent achievement of stress spectra,and checks them with true calculation examples.
