Electro-hydraulic servo blade spring fatigue testing system
Electro-hydraulic servo blade spring fatigue testing
machine
The series testing machine was mainly used for performance
test of the elastic components of coiled spring, Belleville spring, rubber
shock pad, rubber absorber, as well as dynamic fatigue life testing. It could
acquire relevant parameters of static stiffness, dynamic and static stiffness,
dynamic to static ratio and fatigue life etc. It is widely used in experiment
with all kinds of elastic components of surface cars, ships, colleges,
scientific research institutions, rubber industries etc.
