The invention provides a rotating blade excitation testing device and system, which relates to the technical field of rotating blade excitation testing and aims to solve a technical problem that the rotation of a jet chamber of a pneumatic excitation device has high potential safety hazards in the prior art. The rotating blade excitation testing device comprises a driving mechanism, a detection mechanism and a pneumatic excitation mechanism, wherein the driving mechanism is provided with installation positions, the installation positions are used for installing rotating blades, and the drivingmechanism is used for driving the rotating blades to rotate; the detection mechanism is used for detecting the excitation condition of the rotating blades; and the pneumatic excitation mechanism includes an excitation impeller assembly and a brake, the brake is arranged on the excitation impeller assembly, the air flow generated by the rotation of the rotating blades drives the excitation impeller assembly to rotate, and the brake is used for controlling the rotating speed of the excitation impeller assembly. The rotating blade excitation testing device does not need to use the jet chamber which is high in pressure and large in size and has potential safety hazards when conducting an asynchronous excitation test on the rotating blades, and is simple in structure and safe and reliable in use.
Description
technical field [0001] The present application relates to the technical field of vibration testing of rotating blades, in particular to a vibration testing device and system for rotating blades. Background technique [0002] Rotating machinery is a type of important equipment widely used in all walks of life. Rotating blades are key components of rotating machinery. The performance of rotating blades has an important impact on the safety and reliability of rotating machinery. Fatigue is the main failure mode of rotating blades, and the fatigue caused by vibration is the main failure mechanism of fatigue. Therefore, the research on the fatigue of rotating blades generally starts with vibration. [0003] The working conditions of the rotating blades are relatively complex, and there are many factors affecting the vibration of the blades, including speed, pressure, temperature, etc., and it is difficult to establish a reliable mathematical model to analyze the vibration conditi...
