摘要:
提出了基于研磨子的车轮多边形抑制措施，即通过研磨子摩擦车轮踏面从而消除或抑制车轮多边形的产生和发展。台架试验表明，研磨子在保证对车轮踏面均匀磨损的前提下，可有效降低车轮表面粗糙度等级。在线路运用跟踪试验中，配置研磨子车轮的高阶多边形幅值保持在-12.0~7.2 dB之间，表明修形研磨子对车轮多边形的抑制效果明显。
Abstracts:
A wheel polygon suppression method based on abrasive block is proposed, which can eliminate or inhibit the generation and development of wheel polygon by grinding the wheel tread. The bench test shows that the abrasive block can effectively reduce the wheel surface roughness grades on the premise that the uniform wear on the wheel tread is ensured. The amplitude of high-order polygon allocated with abrasive block wheels is kept within -12.0~7.2 dB during the track operation tracking, that shows the abrasive block has obvious restraining effect on the wheel polygon.
