摘　　要：以一种常用的矿用梁类结构的多裂纹故障诊断为研究对象,采用多裂纹迭代细化网格算法研究方法,该方法适合用来诊断多裂纹结构模型,在具体的研究中主要结合大型有限元分析软件ANSYS12.0模拟多裂纹梁的不同工况,根据多裂纹迭代细化网格算法进行大量的分析研究,结果表明,通过真实的数据对比充分验证了诊断结果的准确性和可靠性,证明此类研究方法具有一定的研究意义和应用价值,运用这种研究方法为后续进一步研究奠定了基础。Mainly used to diagnose the multi-crack in mine beam structure model. In the specific research, we mainly combine the large-scale finite element analysis software ANSYS12, which is based on the study of multi-crack fault diagnosis of beam structure. The results show that the accuracy and reliability of the diagnosis result are verified by the real data comparison. The results show that the multi-cracked iterative refinement grid algorithm is used to analyze the different working conditions. This method has a certain research significance and applicati on value, and the use of this research method has laid foundation for further research.
