Industrial robot fault detection and diagnosis for intelligent maintenance: A review of data, methods, and emerging trends

Industrial robots are widely used in intelligent manufacturing due to their high efficiency, flexibility, and repeatability. However, long-term operation under complex working conditions inevitably leads to performance degradation and various faults across mechanical, transmissio...

Sensing limit in blade tip timing measurement and underlying theory

Blade Tip Timing (BTT) is a promising non-contact technique for measuring blade vibrations in rotating machinery due to its minimal hardware intrusion and long service life. However, the inherent mismatch between the high vibration frequencies of the blades and the relatively low...
