The unique feature of the HighPT ultra-high frequency fatigue testing equipment lies in its use of the electromagnetic resonance principle, enabling ultra-high frequency loading up to 2×10⁴ Hz. This brings two key advantages: First, it can reduce the testing time required by traditional methods from several months to several days, achieving high-efficiency and low-cost verification; second, for components subjected to high-frequency vibration (such as aero-engine blades), the testing conditions are closer to the real service environment, and can more accurately reflect the crack initiation and propagation behavior of materials at high frequencies, making it the preferred method for high-cycle and ultra-high-cycle fatigue life material research.
