The EHF-E Series is composed of servohydraulic fatigue testing machines from Shimadzu Europa GmbH. The machines are complete dynamic behavioral evaluation systems, equipped with a completely digital electro hydraulic servo controller. This controller features a high speed loading and data acquisition. The systems provide evaluation of dynamic characteristics such as dynamic spring and damping factors. They can work with a loading of at most 500 Hz in vibration proof materials such as rubber and plastics.
