vertical wheel

From the analysis, it could be concluded that the conditions of the soil, diameter and width of the wheel, vertical load and traction were the factors affecting sliding of the ground wheel.

通过分析得出地表及土壤状况、地轮直径、地轮宽度、地轮上的垂直载荷以及地轮的抓地力是影响地轮机构滑移率的因素。

The results show that the vertical wheel/ rail impact can excite space vibration between wheel and rail, which leads to rail corrugation.

结果表明，轮轨垂向冲击可激起轮轨间横向与纵向的相对振动，从而导致轮轨磨耗数以较高频率变化，使钢轨产生波浪形磨耗。
