The Shimadzu EHF-EM/EV series electro-hydraulic servo fatigue testing machine is a fatigue testing machine that uses a hydraulic servo mechanism. The loading cylinder is located at the lower part of the main engine and is mainly used for testing the static, fatigue, fracture toughness and other properties of standard samples.

Can conduct stress fatigue and strain fatigue tests. After configuring a high-temperature furnace or environmental chamber, high-temperature strain and low-temperature strain fatigue tests can be conducted. After preparing a high-frequency induction furnace, thermal fatigue tests can be conducted.

The EHF-EM series adopts a 4890 control device. The control device is connected to a computer and configured with corresponding experimental software to achieve the setting, control, and data acquisition of experimental conditions.

The EHF-EV series adopts a 4830 control device. This control device can directly set test parameters, test controls, and display test parameters and waveforms from the LCD color touch screen.
