wheel track

But shaping as one of the bevel wheel' cutting technique has not realized the Computerized Number Control completely, it still must use the helix track to realize the spire move.

插齿加工作为斜齿轮切削加工的一种不可替代的加工方法还没有实现完全数字化控制，螺旋导轨依然是实现螺旋运动的机械副件。

In wheel-rail force many detection methods, ground test track method is low cost and relatively accurate method.

在轮轨力众多的检测方法中，地面测试轮轨的方法是成本较低且较为精确的方法之一。

Unlike the operation of a track wheel on a mouse, reading an article from top to bottom on the Mactraption requires an upwards movement on the trackpad instead of a downwards one.

从上到下读一篇文章，需要向下滑动鼠标上的滚轮，使用MacBook操作方法却不同，需要在触控板上向上滑动。

The action of locomotive and rolling stocks on track can be obtained from wheel set model.

机车和车辆对轨道的作用通过轮对模型求得。

And a slide mode control is designed to control the brake moment in this thesis so that the vehicle can track the optimal wheel slip. The effectiveness of this method is verified by the result of simulation.

文中进一步设计了一个滑模控制器控制刹车力矩，使车辆保持对最佳滑移率的跟踪，仿真结果表明这种方法的有效性。

Track Irregularity is the primary cause for producing vibration of locomotive and car and share force between wheel and rail, and the important embodiment in comprehensive performance and carrying capacity for track infrastructure.

轨道不平顺是引起机车车辆产生振动和轮轨作用力的主要原因，是轨道结构综合性能和承载能力的重要体现。

On the conditions that the rail lateral, vertical and torsional vibrations, and the track irregularities are considered synthetically, the wheel rail contact geometry, the wheel track normal contact force model, and the wheel/ rail tangential creep force are solved in details.

详细研究了在充分考虑钢轨横向、垂向和扭转振动以及轨道不平顺作用下，轮轨空间动态接触几何关系、轮轨法向力以及轮轨蠕滑力的求解模型。

It is driven not by the adhesion force from the contact between wheel and rail, but by the electromagnetic force from reaction plate which is mounted in track.

它不是由轮轨间的粘着力驱动，而是由安装在轨道的反应板产生的电磁推力驱动的。

So using CNC substitute helix track and realizing bevel wheel's shaping CNC have important realism meaning.

因此，利用数字控制取代螺旋导轨，实现斜齿插削加工的CNC控制具有重要的现实意义。
