Abstract
With high frequency fatigue experiment machine PX-100, The fatigue behavior test of wheel spoke steel named S500LF was carried out within 100~120Hz frequency, adopting pull - pressure symmetric force test method. Fatigue limit of tesed steel is 291MPa; the S-N curve is illustuated out, and return to the S-N curve equation;The fracture analysis shows that the S500LF wheel spoke steel has good toughness.
