本文从σ—τ复杂应力状态下统一强度理论出发,建立疲劳强度条件,提出了计算绞车轴疲劳强度的一种方法,与常用的安全系数法,有所不同。文中引用了实例来说明其应用。
Based on the unified strength theory under the condition of σ-τ complex stress, this paper establishes the fatigue strength condition and puts forward a method to calculate the fatigue strength of the winch axle, which is different from the commonly used safety factor method. The article cites an example to illustrate its application.
