To provide a device for vibration tests which generates vibration by supplying vibration acceleration with a vibrating means excited to prescribed power, has a simple constitution, reliably controls vibration, and reduces the power consumption.
This device for the vibration test, including a vibration generator which vibrates a sample table whereon a sample is placed, an exciting power source which supplies a DC exciting current to the vibration generator, a vibration detector which detects vibration generated by the vibration generator, and a vibration control circuit which supplies the vibration generator with an AC driving current according to the vibration detected by the vibration detector, includes a driving current detecting part which detects the AC driving current supplied from the vibration control circuit to the vibration generator, and an exciting power switching control part which switches over the DC exciting current supplied from the exciting power source to the vibration generator, according to the AC driving current detected by the driving current detecting part.
