System for be used for tired experiment of vacuum ultrasonic vibration

The utility model discloses a system for be used for tired experiment of vacuum ultrasonic vibration, including piezoelectric transducer and supersound signal generator, piezoelectric transducer's power input terminal connects on supersound signal generator's interchange electrical signal output terminal, still includes the vacuum chamber, connect in test piece on the piezoelectric transducer mechanical oscillation output is located in the vacuum chamber, it produces equipment still to be connected with the negative pressure through the vacuum tube on the vacuum chamber. This system is compared in the tired experimental facilities of current vibration, can simulate by the actual vacuum environment of test test piece, be convenient for obtain directly to reflect the test piece under low pressure vacuum environment, tired performance test numerical value of accurate periodic vibration or measurement numerical value, be convenient for simultaneously obtain carry out quick high frequency fatigue loading even to t
