摘要

随着铁路运输向着更高速度和更高轴载的方向发展,车轮与钢轨之间的疲劳损伤变得越来越严重,大大限制了列车的使用寿命和安全性。因此,开发接触疲劳性能更强的升级轮轨材料被认为是避免损坏的有效方法。本研究报道了一种新开发的具有优异滚动接触疲劳性能的重载车轮钢,并利用新型 RCF 测试仪和视觉系统对车轮的疲劳损伤进行了研究。结果表明,新开发的重型卡车车轮钢(NW)由较小的珠光体层间距和较少的正方体铁素体组成。NW 钢在油和干燥条件下均表现出出色的抗疲劳性能,其疲劳寿命是 CL65 车轮钢的 2.7 倍,性能优于大多数典型的车轮钢。随着珠光体含量的增加和珠光体层间距的减小,车轮在油或干接触条件下的疲劳损伤程度明显降低,从而显著提高了疲劳寿命。适当控制珠光体含量和层间距可以优化车轮材料的疲劳性能。视觉系统观察到,样品表面缺陷的平均面积和周长逐渐增大。在油接触条件下,缺陷的形状变得更加圆润,但在干接触条件下却显示出相反的结果。在循环加载条件下,表面裂纹在产生后沿着不同的路径扩展,最终形成不同的剥离形态。这些结果不仅有助于优化重载铁路的车轮材料,还为分析轮轨接触中的损伤演变提供了有效手段。

A Newly Developed Heavy-Haul Wheel Steel with Excellent Rolling Contact Fatigue Performance Assessed by an Innovative Vision System

As railway transportation advances towards higher speeds and increased axle loads, the fatigue damage between wheels and rails has become more severe, significantly limiting the service life and safety of trains. Therefore, developing upgrade wheel-rail materials with enhanced contact fatigue properties has been considered an effective approach to avoid damage. This study reports a newly developed heavy-haul wheel steel with a superior rolling contact fatigue performance and the fatigue damage of wheel was studied by a novel RCF tester with a vision system. The results indicate that the newly developed heavy-haul wheel steel (NW) consists of smaller pearlite layer spacing and reduced proeutectoid ferrite. The NW steel demonstrates outstanding fatigue resistance in both oil and dry conditions, with a fatigue life 2.7 times longer than CL65 wheel steel and superior performance compared to most typical wheel steels. With increasing in pearlite content and decreasing in pearlitic interlamellar spacing, the fatigue damage degree of wheels under oil or dry contact conditions decreases obviously, leading to a significant enhancement in fatigue life. Properly controlling the pearlite content and the interlamellar spacing can optimize the fatigue properties of wheel materials. The vision system observed that the average area and perimeter of the defects gradually increased on the sample surface. The shape of the defect became more rounded under oil contact conditions but showed the opposite result in dry contact. When subjected to cyclic loading, surface cracks propagated along various paths after initiation, eventually forming different morphologies of peeling. The results will not only help optimize wheel materials for heavy-haul railways, but also offer an effective means for analyzing damage evolution in wheel-rail contact.
