Dynamic and static universal test machine

Summarize

Electro-hydraulic servo dynamic and static universal testing machine is composed of main machine, constant pressure servo pump station, full digital servo controller, control software, Advantech industrial control computer, accessories and pipeline system.

According to the criteria:

ØGB/T3075 “Metal Material fatigue test axial force control method”

According to the need, the necessary auxiliary equipment can be configured for other types of metal, non-metal materials, structural parts, components, assembly into the mobile static fatigue life test.
