Abstract: |
|||
| This invention relates to one micro structure bending fatigue test device based on super magnetic contract principle, which comprises base, super magnetic compound layer contract film and T shape test sample, wherein, the compound layer contract film is divided into three layers with middle of base slice and negative super magnetic contract film and positive super magnetic contract film; there is one concaved tank in center of base and the compound layer contract film is set in the concaved tank with one end fixed on base to form hanging beam and other end connected to T shape test sample fixed on the base. | |||
