Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic fatigue experiments, in particular to an ultrasonic fatigue experiment specimen heating system. Background Art

[0002] Ultrasonic fatigue testing is a new technology for evaluating the fatigue properties of materials. It uses a piezoelectric ceramic transducer to convert the electrical signal from a high-frequency power supply into mechanical vibrations of the same frequency, which are then amplified by a vibration displacement amplifier. One end of the specimen is connected to the displacement amplifier, while the other end is free. Under the excitation of the displacement amplifier, resonance occurs, generating resonant waves in the specimen.
