The MVC-2M Fault Diagnosis System — an achievement of the national key research task in this field is presented in this article. The system can be used in various fields such as marine power engines, power generation, petrochemical industry, aviation and space, machine building etc. The basic functions of this system include real-time condition monitoring, on-line and off-line fault diagnosis, establishment of operation database, storage of fault data in blackbox, calibration of vibration measuring instruments, analysis of structural dynamic characteristics, local dynamic balancing, and so on.
This article also presents several practical experieces during its term of service in Chinese naval vessels and power stations. It is widely confirmed that the MVC-2M system is essential to forecast the faults which probably would happen and thus is successful for avoiding the serious damage of the machines in motion.
