摘要

Rotating blades are critical components in turbomachinery, operating under extreme thermal and mechanical conditions. Understanding their vibration behavior is essential for improving system reliability and efficiency. This paper presents a comprehensive review of existing theoretical and experimental studies on the vibration response of rotating blades subjected to thermal environments. It emphasizes the application of beam theories, analytical and semi-analytical methods for governing equation formulation, and simulation and numerical techniques for response prediction. Experimental approaches for vibration measurement, specifically related to rotating structures, are also discussed. The paper highlights how blade configuration and loading conditions influence vibrational characteristics.
