Vibration test device based on magnetic induced shrinkage or elongation

The utility model discloses a vibration test device based on magnetic induced shrinkage or elongation. The vibration test device comprises a support, a magnetic induced shrinkage or elongation mechanism and a workbench surface. The magnetic induced shrinkage or elongation mechanism is fixedly installed on the support, the movable end of the magnetic induced shrinkage or elongation mechanism is also fixedly connected with the workbench surface through at least one lever mechanism, the lever mechanism comprises a lever, one end portion of the lever is connected with the movable end of the magnetic induced shrinkage or elongation mechanism, the other end of the lever is fixedly connected with the workbench surface, and a support mechanism is also arranged at a selected position between the two ends of the lever. The vibration test device provided by the utility model has the following advantages: the structure is simple, the work performance is stable, the work frequency can be conveniently adjusted within a quite wide range, the accuracy of a rest result can be improved, not too much heat is generated during a work process, the device is basically free from noise and pollution, the application of a cooling mechanism is unnecessary, the energy consumption is low, and the device has wide application prospects.
