Servohydraulic dynamic testing machine

Description Applications Contact us

Servohydraulic fatigue testing machine is mainly used to test the static and dynamic mechanical properties of metal and non-metal materials. It can realize tensile, compression, tension-tension, compression-compression, tension-compression and other mechanical tests, but also can realize high cycle fatigue, low cycle fatigue, crack growth, fracture toughness and other tests, to achieve sine wave, triangular wave, square wave and other waveform output.

Features

The upper crosshead and the lower actuator form a closed frame structure, which has large rigidity, no reverse clearance and good stability;
The actuator adopts bidirectional acting cylinder design, reasonable space design and easy operation;
Crosshead lifting, locking, and specimen clamping are operated by the button, flexible and convenient.
