在研究蒙皮划伤的性质和受力特点基础上,采用 COSMOS软件计算了划伤蒙皮的最大应力,基于疲劳寿命估算方法得到了循环载荷下构件的疲劳寿命,分析了不同划伤深度和划伤形式对机身增压蒙皮结构应力集中和疲劳寿命的影响。
Based on the study of the nature and force characteristics of skin scratching, COSMOS software was used to calculate the maximum stress of the skin. The fatigue life of the components under cyclic loading was obtained based on the fatigue life estimation method. The effects of different scratch depths and Effect of Scratch Pattern on Stress Concentration and Fatigue Life of Body Supercharging Skin Structure.
