自20世纪70年代以来，已经有大量的研究结构健康监测，但这种研究工作已经取得了相对较少的常规工业应用。结构健康监测可以包括具有非常不同的要求的非常不同的结构上的应用;本文将主题分为四大类：旋转机器状态监测、大型结构的全局监测（结构识别）、大区域监测（覆盖的区域是较大结构的一部分）和局部监测。在每一类技术的能力和潜在的应用进行了讨论。旋转机械部件的状态监测与其他类别有很大的不同，因为它并不严格关注结构健康。然而，它通常与结构健康监测相关联，并且是一个相对成熟的领域，具有许多常规应用，因此可以在主流结构健康监测中阅读有用的经验教训，其中工业应用较少。结构健康监测从研究到实际应用进展缓慢的原因包括对监测的商业案例缺乏关注，对如何处理大数据流的关注不够，以及缺乏对工业环境中真实的结构的性能验证。这些问题进行了讨论，并提出了前进的方向，它的结论是，更好地集中研究和开发考虑这里确定的关键因素，结构健康监测有可能遵循旋转机械状态监测的路径，并成为一个广泛部署的技术。
There has been a large volume of research on structural health monitoring since the 1970s but this research effort has yielded relatively few routine industrial applications. Structural health monitoring can include applications on very different structures with very different requirements; this article splits the subject into four broad categories: rotating machine condition monitoring, global monitoring of large structures (structural identification), large area monitoring where the area covered is part of a larger structure, and local monitoring. The capabilities and potential applications of techniques in each category are discussed. Condition monitoring of rotating machine components is very different to the other categories since it is not strictly concerned with structural health. However, it is often linked with structural health monitoring and is a relatively mature field with many routine applications, so useful lessons can be read across to mainstream structural health monitoring where there are many fewer industrial applications. Reasons for the slow transfer from research to practical application of structural health monitoring include lack of attention to the business case for monitoring, insufficient attention to how the large data flows will be handled and the lack of performance validation on real structures in industrial environments. These issues are discussed and ways forward proposed; it is concluded that given better focused research and development considering the key factors identified here, structural health monitoring has the potential to follow the path of rotating machine condition monitoring and become a widely deployed technology.
