摘　　要：以深水钻井隔水管的全尺寸弯曲疲劳试验为契机,对共振式疲劳试验方法的实际应用进行了探索。基于该方法在隔水管疲劳试件设计、试验过程及结果分析等方面进行了系统分析和研究。试验测试结果证明了采用有限元模态计算进行隔水管全尺寸疲劳试件结构设计的正确性。通过理论加载曲线和实测加载历程的对比验证了共振式弯曲疲劳试验加载方法的正确性。该试验的成功为共振式疲劳试验方法和相应试验设备在大直径管材全尺寸疲劳试验领域的深入应用提供了参考。Taking full-size bending fatigue test of deep-water drilling riser as an opportunity,the practical application of resonance fatigue test method is researched.Based on resonance fatigue test method,the systematic study is developed on designing of fatigue samples,testing process and results analysis.By using finite element modal analysis,Actual test results proved that the structure designing of full-size fatigue samples with modal analysis is correct.At the same time,through the comparison between theoretical load curve and measured load curve,it is demonstrated the accuracy of loading alternating stress with resonant bending fatigue testing method.The successful development of this test provide a reference on further engineering application of the resonant method and corresponding test equipment in full-size fatigue test field of domestic large diameter pipe.
