→ 30KN / 100KN rubber elastic cushion/pad fatigue testing machine, is used to apply vertical load on CRT III type elastic cushion at a constant frequency. Measure the permanent deformation after 3 million load cycles.
→After 3 million load cycles, take out the elastic cushion and place it in the environment of 23±2.0℃ for 24 hours and then tested by stiffness test to get static stiffness after fatigue test. The change rate of static stiffness of elastic cushion before and after fatigue was calculated.
