HDT-B servohydraulic dynamic testing machine

It is mainly used to test the static and dynamic mechanical properties of small metals, non-metallic materials, spare parts and elastomers. It can realize tensile, compression, bending, tension, compression and tension and other mechanical tests, but also can realize high cycle fatigue, low cycle fatigue, crack growth, fracture mechanics tests, to achieve sine wave, triangle wave, square wave and other waveform output.

 Features:

  • The upper beam and the lower actuator form a closed frame structure, the frame stiffness is large, no reverse clearance, good stability;

  • The actuator adopts bidirectional acting cylinder design, the space design is reasonable and the operation is convenient;

  • Moving beam lifting, locking and sample holding are operated by the button, flexible and convenient.
