The customer's customized four column electro-hydraulic servo fatigue testing machine was delivered on time, and all performance indicators met the contract requirements. The customer expressed great satisfaction.
Fatigue testing machine is a specialized equipment used to test the performance of materials or structures under repeated loads. It mainly simulates the cyclic stress conditions in actual use to evaluate their fatigue life, durability, and crack propagation characteristics.
1. Core functions
Fatigue life testing: Determine the number of cycles in which a material or component fractures under alternating loads.
Stress strain analysis: monitoring the mechanical response of materials under cyclic loading.
Research on crack propagation: Observing the initiation and propagation patterns of fatigue cracks.
Environmental simulation: Optional modules such as temperature control and corrosive media can be configured to simulate complex working conditions.
2. Main types
By loading method:
Axial fatigue testing machine: Apply bidirectional tensile compressive loads.
Rotating bending fatigue testing machine: applies bending stress by rotating the specimen (commonly used in metal shaft testing).
Torsion fatigue testing machine: tests the performance of materials under cyclic torque.
According to the control mode:
Electromagnetic resonance type: high frequency and low load, suitable for small samples.
Hydraulic servo type: high load, high precision, can simulate complex waveforms.
Electric type: suitable for mid to low frequency applications, easy to maintain.
3. Testing standards
International standards: ASTM E466 (metal axial fatigue), ISO 1099 (bending fatigue).
Industry standards: such as SAE J1099 (automotive parts), EN 6072 (aviation materials).
4. Application Fields
Aerospace: Fatigue testing of engine blades and fuselage structures.
Automotive industry: Durability verification of suspension, wheel hub and other components.
Materials Science: Research on metals, plastics, and composite materials.
Biomedical: Fatigue performance evaluation of artificial joints and bone plates.
Civil engineering: life prediction of bridges and welded joints.
