Electric-Hydraulic Dynamic and Fatigue Testing System

Servopulser series electric-hydraulic dynamic and fatigue testing systems feature servo-hydraulic actuators, which are able to accurately
reproduce input waveforms. Therefore, they are highly accurate in applying loads ranging from low to high. From high-performance standard
models to products customized to satisfy various unique testing requirements, these systems support a wide range of dynamic testing EHF Series Electric Hydraulic Dynamic and Fatigue Testing System
applications.

High Capacity and Compact

By controlling the ow rate of oil, compact hydraulic actuators can apply large
forces at a wide range of testing speeds, from extremely slow to very fast. This
means they can be used for a wide variety of testing applications.

High-Rigidity Frame

A very rigid loading frame is used to prevent buckling samples. EMT/NJ-SERVO/MMT Series Electric Fatigue and Endurance Test System
This ensures high reliability for a variety of testing applications.

From Low to High Speeds
From Low to High Loads

High-performance servo valves allow seamless and immediate change of the test
force or speed.

An Energy-Saving Operating
Mode Is Also Available

By using the optional energy-conservation unit (ECU) (page 36), an
energy-saving mode can be used to optimize the hydraulic power supply unit's
power level based on the testing parameters and testing status. It reduces the Controller for Dynamic and Fatigue Testing Systems
