Classification:

According to the different linear actuators of the force application device, they can be divided into two categories: 1. Electro hydraulic servo fatigue testing machine 2. Electro hydraulic servo torsional fatigue testing machine.

The structure of the equipment should ensure sufficient dynamic and static strength, stiffness, stability, and high precision, ensuring that the system has good dynamic quality. The selected servo system execution components have high precision, good reliability, strong resistance, and fast response speed

The fatigue resistance performance of materials and components is mainly tested through tensile and compressive fatigue tests. During material fatigue, the fracture propagation theory of cracks inside the material is also studied and tested.
