中文摘要:
      针对外物损伤(FOD)对压气机叶片高周疲劳(HCF)强度的影响特点及其规律,总结了国内外研究现状及预期发展趋 势。从FOD特征对压气机叶片HCF强度的影响、残余应力以及激光强化对HCF强度的影响、FOD叶片数值模拟以及FOD叶片寿 命模型等方面,对现有研究成果进行综述。分析表明:FOD从多方面影响着压气机叶片的HCF强度,并有着一定的规律性,如:60° 是较为危险的一种冲击角度,随着外物冲击损伤深度的增加会降低叶片的强度,残余拉应力的产生可以提高叶片疲劳强度,适当 的表面处理同样可以提高叶片的强度。现有的FOD对压气机叶片HCF强度研究存在以下问题:试验有待进一步改进,理论模型 有待深入研究,残余应力对叶片HCF强度的影响规律尚不统一等。
英文摘要:
      According to the characteristics and laws of the effects of foreign object damage(FOD)on high cycle fatigue(HCF) strength of compressor blades,the research status at home and abroad and the expected development trend are summarized. The effects of FOD characteristics on the HCF strength of compressor blades,the effects of residual stress and laser shock peening on the strength of HCF,the numerical simulation of FODed blades,and the life model of FODed blades are reviewed. The analysis shows that FOD affects the HCF strength of compressor blades in many ways and follows some common rules,such as,the impact angle of 60 ° is dangerous,the increase of impact depth will reduce the strength of the blade,and the tensile residual stress can improve the fatigue strength of the blade, appropriate surface treatment can also improve the strength of the blade. There are some problems in the existing FOD research on the HCF strength of compressor blades:The experimental methods need to be further improved,the theoretical model needs to be more thoroughly studied,and the laws of the influence of residual stress on the HCF strength of compressor blades are not uniformed.
