Research on fretting fatigue life of anisotropic materials

  • 摘要: 设计和制造了一套采用液压加载方式来施加法向载荷的微动疲劳试验装置,并且在该装置上进行了各向异性材料DD3与粉末高温合金FGH95以及DZ125与FGH95配对接触的微动疲劳试验,研究其微动疲劳的损伤过程.各向异性材料微动疲劳试验的完成证明了该装置的性能良好.将微动综合损伤参量应用于各向异性材料微动损伤的表征,并建立了DD3和DZ125相应的微动疲劳寿命预测模型.通过微动综合损伤参量的计算分析与试验验证,表明所建立的各向异性材料微动疲劳寿命模型其预测结果误差分散带均在2.8倍因子以内.
