摘    要：本文分析了受非零平均应力的复合应力作用的轴的疲劳强度设计.提出了与强度理论相结合的通用计算公式.这些公式是按线性疲劳界限导出的.还提出了平均应力为负值时轴的疲劳强度设计公式.

Abstract: This paper summarily analyses the fatigue design of shafts subjected to combined stresses with nonvanishing mean stress. The most general form of the design equations, which incorporates with strength theories, is given. These equations are obtained according to the linear criteria which define the fatigue failure line. The author also proposes the experessions of the fatigue design of shafts, when the mean stress is in compression.
