Dynamic fatigue testing machine

Description

Description
   PWS series electro-hydraulic servo dynamic testing system consists of frame, pump station, servo control system, computer and software, accessories and pipeline system. It can be applied to dynamic fatigue and static performance test of various materials, structural parts and components.
 
Application
1.Dynamic high cycle fatigue test and low cycle fatigue test
2. Conventional mechanical property test and fracture force test under the control of static constant rate, constant strain and constant stress.
3. Part vibration and impact test
4. Fatigue life, crack growth, fracture toughness performance test for material or components.
5. Safety evaluation and working condition simulation of actual specimens.
6. It is applicable to quality control and experimental research in the fields of aerospace, aviation, vehicles, building components, rail transit, atomic energy and ship.
