The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.

本文建立了车轮轮缘贴靠钢轨形成的轮轨两点接触和共形接触的计算模型，对不同的牵引力矩、不同的横向力作用下的轮轨接触力、接触状态和轮轨应力分布进行了详细的分析，得出了轮轨间横向力增大会降低机车粘着性能等一系列重要结论。

Its crowning sculpture of the four-headed lion has been adopted as the symbol of the Republic of India, while the symbol of the chakra that once surmounted it has been used as the central motif of the Indian flag.

其率领的狮子雕塑加冕四获得通过，成为印度共和国的象征，而车轮象征的查克拉，一旦克服它已被作为印度国旗中央的图案。

When the car is running on bumpy roads and burdened the shock from wheels, the frame will bend and be tortured and these deformations will influence in turn on the functions of the car assemblies.

汽车行驶在凹凸不平的路面以及受到车轮的冲击负荷时，车架要产生弯曲和扭曲变形，这些变形都会影响各个总成的工作。

At last, the day he had been waiting for his whole life arrived. With a bouquet of fresh-picked daisies in hand, he left for the train depot. Steam billowed and wheels screeched as the train crawled to a stop.

最后，终于迎来了期待已久的全新生活到来的一天，拿着一大束刚刚采摘过的雏菊来到火车站，汽笛和车轮发出巨大的响声，火车要停了。

In modeling process, the elastic characteristics between rim and outside-wheel were considered and the friction solution algorithm under slip and stick conditions was developed.

详细阐述了车轮在静、动两种状态下接触摩擦力的求解方法。

Unlike traditional hybrids, the gas motor never drives the wheels directly.

与传统的混合动力汽车，燃气汽车从未直接驱动车轮。

While he was passing along the boulevards the roll of the last carriages deafened him with the name of Nana; the gaslights set nude limbs dancing before his eyes--the nude limbs, the lithe arms, the white shoulders, of Nana.

他沿着一条条大马路走时，夜间最后几辆马车的车轮的辘辘声，仿佛是呼唤娜娜名字的声音，简直把他的耳朵都震聋了。

The influence of train running speed, wheel-rail friction coefficient, vehicle load, track geometric irregularity, partly load, gauge and the shape of wheel tread on derailment was emphasized.

论文重点分析了车辆运行速度、轮轨摩擦系数、车辆载重、轨道几何不平顺、偏载、轨距大小、车轮踏面形状等因素对脱轨的影响。

No one can keep the wheel of history going forward.

没有人能阻止历史的车轮前进。

Luckily we were not going very fast when the wheel spun off and the car crashed in the lawn .

还算幸运，车轮甩出来车子闯入草坪时，我们的车开得还不算太快。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
