| 摘要 | PURPOSE:To omit a steam apparatus and to perform safe operation without wetting, by blowing air as a vibration source to the blades of a rotating rotor with a pressure from a nozzle. CONSTITUTION:Air is blown from a nozzle 14 to blades 13 of a test rotor 10, which is supported by a bearing 15 in a vacuum chamber 11. Vibration is applied in this way, and a rotary vibration test is conducted. Since the air is used as a vibration applying fluid, a steam apparatus is not required. Since the steam is not used, the equipment is not wetted. The air is readily available and the operation is simple. Therefore there is no danger. Since the air has larger specific gravity than the steam, the effect of the vibration-application effect is large. | ||||||
