| description | The invention discloses a gas compressor circle-arc tooth rotor blade vibration fatigue test fixture. The gas compressor circle-arc tooth rotor blade vibration fatigue test fixture comprises a pedestal and a circle-arc tooth tenon chuck which is formed by combining an upper positioning block with a lower positioning block. An included angle is formed between the chuck installation surface of the pedestal and the connecting surface of the lower end of the pedestal and a shock excitation table. The effect that the energy releasing directions of blade bodies and the shock excitation table are perpendicular can be guaranteed through the included angle. By means of the gas compressor circle-arc tooth rotor blade vibration fatigue test fixture, the phenomena that vibration transmission of the fixture is insensitive in the vibration fatigue testing process, breakage happens between connecting pieces, the vibration transmission is incontinuous or is stopped suddenly, and accordingly the vibrational frequency value is |
