摘　　要：基于Hyper Works平台,在理论分析的基础上,对试样进行了有限元应力分析,分析结果与理论值吻合的很好,并对孔边进行了自由形状优化,获得了精确的孔边几何形状,降低了应力集中,为进一步疲劳分析提供了可靠的几何形状依据,大大提高疲劳试验的效率和可靠性。On the basis of HyperWorks platform and theoretical analysis, the finite element analysis of stress has been conducted to the sample. The analysis result accords well with the theoretical value. The accurate hole edge geometry has been obtained by optimizing of hole edge free profile. The stress concentration has been reduced, which provides reliable geometry reference for the fatigue analysis, and improves the efficiency and reliability of fatigue test.
