Abstract: With the flourishing development of mechanical equipment, such as aerospace vehicle, high-speed train, nuclear power plant and wind turbine, the mechanical Structural Health Monitoring (SHM) which could ensure the high performance and reliability of mechanical structures has been universally emphasized. By SHM, the mechanical structure can be monitored online during the service process of structure. In addition, the scheduled maintenance can be replaced by the as-needed maintenance. As a result, the structural maintenance cost can be reduced while the safety and reliability of the mechanical structure can be ensured. A review of the critical aspects of the mechanical SHM is presented. First, the development status of mechanical SHM in aerospace, energy and chemical industry, wind turbine and high-speed railway is illustrated. Then, concerns regarding of the advanced sensing technology, SHM systems and SHM methods commonly used in mechanical SHM are presented and reviewed. Finally, the crucial points for further exploring methods and technologies of the mechanical SHM are summarized.
