Valve Spring Fatigue Testing Machine
The Valve Spring Fatigue Testing Machine is a specialized testing device used to evaluate the fatigue life, fatigue limit, durability, and performance stability of tension and compression coil springs. It simulates repeated working conditions to analyze the fatigue characteristics of valve springs and other elastic components under different frequencies.
Application
The Valve Spring Fatigue Testing Machine is mainly used for fatigue tests and fatigue limit tests of tension and compression coil springs. By changing the vibrating mass, it can perform fatigue life tests of the same type of spring at different frequencies, and obtain the fatigue life curves of springs under different frequencies.
With appropriate modifications of fixtures, it can also be used for fatigue testing of other types of elastic components.
It is suitable for all industries involved in the manufacturing and application of springs.
