100 kN High-frequency Fatigue Testing Machine

100 kN Electromagnetic resonance high-frequency fatigue testing machine

The high-frequency fatigue testing machine is an electromagnetic excitation resonance type fatigue testing machine, mainly used for high-frequency tensile and compression testing of metal materials and components, as well as fatigue performance and fracture mechanics performance testing under alternating tensile and compressive loads. Equipped with corresponding fixtures, it can also perform three-point and four point bending, compact tensile testing, plate specimen tensile testing, fatigue testing of gears, bolts, connecting rods, chains, etc. It can also perform micro observation crack propagation rate and programmable loading tests.
