摘要

在JD-1型轮轨模拟试验机上,通过改变冲角,研究了干态工况下曲率半径对PD3和U71Mn钢轨滚动接触疲劳性能的影响.结果表明,随曲率半径减小,钢轨磨损量增大,流变层增厚且不均匀.PD3钢轨有较好的抗磨损性能,但疲劳裂纹损伤严重;U71Mn钢轨有良好的抗疲劳性能.

Abstract:

The effect of curve radius on the rolling contact fatigue properties of PD3 and U71Mn rails was investigated on JD-1 wheel/rail simulation facility with different attack angles.The results indicate that with a decrease in curve radius the wear volume of rail roller increases,and the plastic flow layer becomes thicker and uneven.PD3 rail has higher wear resistance,but lower fatigue resistance,than U71Mn rail does.U71Mn rail shows an excellent anti-fatigue property.

Keywords: rail   curve radius   fatigue crack   contact fatigue   wear
