发现名义滚动圆处研磨子磨耗分量的速率在二阶段中一、二期内分别为0.12

It is found that the velocity of the abrasive wear component at the nominal rolling circle is 0.12 and 0.02 mm/10,000 kilometers in the first and second phases of the second stage, and the velocity of the wheel-rail wear component is about 0.08 mm/10,000 kilometers.

It was found that the rate of grinding components at the nominal rolling circle was 0.12 and 0.02 mm/10,000 km respectively in the first and second stages of the second phase, and the rate of grinding components of the wheel rail was about 0.08 mm/10,000 km.

It is found that the wear rate of the grinding wheel at the nominal rolling circle is 0.12 mm / 10000 km and 0.02 mm / 10000 km respectively in the first and second stages, and the wheel / rail wear component is about 0.08 mm / 10000 km.<br>
