The electro-hydraulic servo fatigue testing machine (multi-function load fatigue, supporting customization on demand) is suitable for static compression test and dynamic fatigue test of various large parts such as concrete structural parts, rails and their welded joints, guide rail fastener assembly, bridges, trusses, automobile chassis, automobile axles, locomotive bogies, springs, etc. Equipped with a special test device, the fatigue load performance test of steel strand for prestressed concrete and anchorage connector fixture for prestressed reinforcement can be completed. It is a fatigue life test and detection system with wide application range, reliable performance and low running cost in dynamic load fatigue performance detection fields such as railways and transportation. Our HSDT series electro-hydraulic servo fatigue testing machine is developed and produced by our company for the Highway Research Institute of the Ministry of Communications. The theoretical maximum displacement of the system is 800ml/ time, and the maximum amplitude of 1000KN actuator can reach 15 mm. The successful development of this system has established China's leading position in electro-hydraulic pulse testing machine technology in the world. This series of testing machines have the advantages of reasonable structure, reliable operation, low operation cost, no need of cooling, energy saving and environmental protection, and wide application range.
