高速和低速工况下列车车轮的损伤行为对比
Comparison of Damage Behaviors of Railway Wheel under High and Low Speed Conditions
摘 要
在轮轨模拟试验机上模拟了列车车轮在高速(350 km·h-1)和低速(120 km·h-1)工况下的运行过程, 对比分析了两种工况下车轮的损伤行为。结果表明: 两种工况下车轮试样均出现了非均匀磨损, 表面磨痕沿车轮滚动方向交替出现了光滑区域和粗糙区域; 低速工况下车轮试样的磨损量明显大于高速工况下的, 其粗糙区域和光滑区域的损伤差异性较大, 而高速工况下两个区域的损伤差异性较小。

Abstract
The running processes of railway wheel under high speed (350 km·h-1) and low speed (120 km·h-1) conditions were simulated on the wheel/rail simulation facility, and the the damage behaviors of the wheel under the two conditions were compared and analyzed. The results show that the irregular wear appeared on both wheel specimens under the two conditions, namely the smooth and rough region appeared alternately along the rolling direction of wheel on the surface wear mark. The mass loss of wheel specimen under low speed condition was significantly greater than that under high speed condition and the damage difference was relatively large between smooth and rough areas. However, under the high speed condition, the difference was relatively small.
