The Series electro magnetic resonance fatigue testing machines are used for fatigue tests of metal material and component under tension, compression or reversal load. If the relevant grips are provided, three-position bending test, four-position bending test, tension and compression of sheet sample test, tension and compression of circle test, gear wheel, bolt, connecting rod, roller chain, crackle expanding test are available.

The serial testing machines undergo optimization design and the structure is rational. The automatically controlled system adopts the advanced pulse wide control system and new-type power amplifier to improve the reliability of the electric system. It is with high efficiency, easy to shake, shake, low energy consummation, high controlling accuracy, small fluctuation.
