What is a Fatigue tester?

A fatigue tester is a device used to evaluate how materials or components endure repeated loading or stress. This test examines the effects of cyclic loads or vibrations over an extended period, simulating the conditions that could cause fatigue failure in products. Fatigue testing is crucial in industries such as aerospace, automotive, construction, and bridges, where parts or structures are subjected to repeated stresses during use.

The fatigue tester applies repetitive tensile or compressive forces to a material in cycles and measures its durability until failure occurs. This allows manufacturers to determine the stress levels at which a material or component will fail due to fatigue, providing vital data for ensuring the product’s safety during use. For example, it is used to determine the fatigue limit of metals or estimate the lifespan of components subjected to repetitive motion.

Fatigue testing plays an essential role in product development and safety by predicting how long products can withstand repeated stresses, ensuring reliability and longevity.

Application of Fatigue tester

１．Automotive Components – Fatigue testing is used to evaluate the durability of components like suspension parts, drive shafts, or engine components, which are subject to repeated stresses during vehicle operation.
２．Aircraft Parts – In the aerospace industry, fatigue testers are used to test components such as wing structures, landing gear, and fuselage parts, which experience repeated loading and unloading during flight cycles.
３．Bridge Components – Fatigue testing helps assess the long-term durability of bridge materials like steel beams or concrete supports, which endure cyclical loads from traffic and environmental factors.
