技术诊断的研究发展与在土木工程中的应用

The research and development of technical diagnosis and its application in civil engineering

综述了技术诊断学在国内外的研究发展状况及技术诊断学在土木工程中的应用.介绍了当前技术诊断的常用方法,重点讨论了对频响函数的监测和高阶固有频率在损伤诊断的应用和存在问题及其研究发展方向.

This paper illustrates current research achievements and development status of technology diagnostics in domestic and overseas, as well as the application of the technology diagnostics used in civil engineering. Moreover, this paper also introduces a variety of approaches of technology diagnosis that are in common use today and puts emphasis on discussing the approaches of monitoring frequency response function, the application of high order inherence frequency in trauma diagnosis, the existing problems and the further development orientation of these technologies.
