description | With the continuous progress of the vibration test technology, the vibration fatigue test has a good test basis and can carry out the vibration fatigue simulation test under various environment. However, the current measurement methods of vibration fatigue can not meet the needs of in-depth study of vibration fatigue test. The method of synchronous measurement of vibration fatigue of aluminum alloy is put forward. At the same time, the vibration fatigue specimens of aluminum alloy under different accelerations are measured by infrared monitoring technology, acoustic emission technology, micro-test technique and strain testing technology. The changes of various measurement parameters with the damage are studied. It is concluded that different measurement parameters should be taken into account in different stages of vibration fatigue of aluminum alloys as the basis for judging damage. Acoustic emission signals can detect crack initiation and propagation life of vibration fatigue of aluminium alloy very well. The temperature rise measured by infrared is non-linear with the increase of acceleration. And a new phenomenon is found that the vibration fatigue life of aluminum alloys also depends on structural vibration frequency, damping and other parameters. |
