What is a hydraulic fatigue testing machine?
Hydraulic fatigue testing machine is a testing equipment used to simulate the fatigue performance of materials or components under alternating loads. It applies cyclic loading through a hydraulic system to evaluate the durability and longevity of materials under long-term repeated stress. It is widely used in aerospace, automobile manufacturing, construction engineering and other fields, and is an important tool for studying the mechanical properties of materials.
