    Fatigue Life Analysis of Carbon Fiber Reinforced Metal Matrix Composites

      摘要
    • 摘要: 在同一扭矩作用下，对不同铺层角度的SiC/TC17轴和TC17轴进行计算分析，并采用局部应力应变法对轴的疲劳寿命进行预估，研究SiC/TC17轴相较于TC17轴疲劳寿命的特点和SiC/TC17轴的疲劳寿命随不同铺层角度变化的规律。结果表明：在单向铺层的0°~90°范围内，SiC/TC17轴的疲劳寿命随铺层角度的增加而增加，到45°时疲劳寿命达到最大；随着角度继续增大，SiC/TC17轴的疲劳寿命随铺层角度的增加而减少；交叉铺层的±45°SiC/TC17轴的疲劳寿命比单向铺层的45°SiC/TC17轴的疲劳寿命长。

       

      Abstract: The SiC/TC17 shafts with different layer-paving angles and TC17 shaft were calculated and analyzed under the same torque. The fatigue life of SiC/TC17 shafts was estimated by local stress-strain method. The fatigue life characteristics of the SiC/TC17 shafts compared with TC17 shaft and the variation rule of fatigue life of SiC/TC17 shafts with layer-paving angle were studied. The results show that in the range of 0°~90°, the fatigue life of SiC/TC17 shafts first increases with the increase of layer-paving angle and reaches the maximum at 45°, and then it decreases with the angle rising. The fatigue life of cross-laying ±45° SiC/TC17 shaft is longer than that of unidirectional-laying 45° SiC/TC17 shaft.
