Fault monitoring of rotating rectifier in aviation brushless AC generator is a technical problem. Although various diagnosis methods have been developed, they all use the relatively complex algorithms, which increase the software and hardware complexity of generator control unit extremely. A simple and practical monitoring circuit has been designed based on harmonic armature reaction principle of...
In this paper, we introduce a telescopic manipulator that is used in the narrow space inside the steam generator of the nuclear power plants for video inspection. Mimicing the structure of tape measure, we design the structure of the manipulator, and apply finite element analysis method to analyze the key parts of the flexible arm. There are many factors exerting influences on the manipulator and...
