Testing Principle
The machine simulates cyclic riding loads applied to bicycle frame structures during long-term riding conditions.
The horizontal fatigue test evaluates the durability performance of the head tube area under alternating tension and compression loads.
The vertical fatigue test evaluates frame structural integrity under repeated vertical loading conditions to verify fatigue resistance and service life performance.
