Or as one who yokes broad-browed oxen that they may tread barley in a threshing-floor- and it is soon bruised small under the feet of the lowing cattle- even so did the horses of Achilles trample on the shields and bodies of the slain. The axle underneath and the railing that ran round the car were bespattered with clots of blood thrown up by the horses' hoofs, and from the tyres of the wheels; but the son of Peleus pressed on to win still further glory, and his hands were bedrabbled with gore.

像农人套起额面开阔的犍牛，踏踩着雪白的大麦，在一个铺压坚实的打谷场上，哞哞吼叫的壮牛，用蹄腿很快分辗出麦粒的皮壳――就像这样，拉着心胸豪壮的阿基琉斯，捷蹄的快马踢踏着死人和战盾，轮轴沾满飞溅的血点，马蹄和飞旋的轮缘压出四散的血污，喷洒在围绕车身的条杆。

With this he lashed his goodly steeds, and when they felt the whip they drew the chariot full speed among the Achaeans and Trojans, over the bodies and shields of those that had fallen: the axle was bespattered with blood, and the rail round the car was covered with splashes both from the horses' hoofs and from the tyres of the wheels.

言罢，他举起脆响的皮鞭，驱赶长鬃飘洒的骏马，后者受到鞭击，迅速拉起飞滚的战车，奔驰在两军之间，踏过死人和盾牌，轮轴沾满飞溅的血点，马蹄和飞旋的轮缘压出四散的污血，喷洒在围绕车身的条杆。

These four aspects are: the foreworn and frature of the wheel rim , tread foreworn bedded d ecrustation, regional crush and subside and early brittle fracture of the wheel rim .

为了有效地提高行走车轮的工作寿命，使其接近或达到设计周期，笔者从车轮损坏的形式、部位即轮缘磨损断裂、踏面磨损层状脱皮和局部压碎凹陷、轮缘早期脆性断裂四个方面进行了分析，找出了之所以产生磨损和断裂的原因，并提出了延长车轮工作寿命的对策。

The author has accomplished the following tasks:1. presented the general scheme of the profile measuring system;2. presented four methods of laser collimation, realized 3 of them with the software of ZEMAX, and meted the requirement of the system design;3. realized the laser beam expanding from point-laser to line-laser wide enough to cover the flange trackside;4. after image grabbing and processing, picked up the profile of the train wheel.

作者独立完成的工作包括： 1、提出了曲面测量的光学系统的整体方案； 2、提出了四种激光扩束的方案，用光学设计软件ZEMAX完成了其中三种的设计；经过像差分析和追迹，达到了准直扩束的要求； 3、点光源到线光源的单方向扩展，达到了覆盖轮缘踏面的要求； 4、通过实验采集图像和图像处理，提取出被测轮缘的轮廓。

Focusing on severe wheel flange/rail side wear and a series of derailments of tramway vehicles with independently rotating wheels, an investigation has been carried out by comparison against solid wheelsets. Based on MATLAB/SIMULINK and a self-developed simulation model considering the IRWs, derailments have been simulated with results of possible causes of such derailments. Efforts have been made to fulfill comprehensive treatment of controllable factors such as the wheel profile, lubrication, clearance between check rail and high rail etc.

针对目前具有独立轮转向架的低地板面轻轨列车所发生的脱轨问题和轮缘严重磨耗间题，从轮轨系统的基本关系出发，分析了传统刚性轮对与独立轮对的导向机理和特点，建立了具有独立轮特点的计算机仿真模型，采用MATLAB/SIMULINK仿真工具计算模拟了实际脱轨现象，并对各种可能导致脱轨和轮缘磨耗的因素进行了分析。

The bridge type derrick big car will appear to chew track phenomenon in the movement, slight of chew a track will result in a good luck and orbit of the on the side have obvious of wear away trace, severity chew a track will result in a good luck and orbit of the on the side metals be peeling off or the round's good luck outwardly transform and even jump the track to result in graveness Human body dead and injured and equipments trouble.

桥式起重机大车在运行中会出现啃轨现象，轻微的啃轨会造成轮缘及轨道的侧面有明显的磨损痕迹，严重啃轨会造成轮缘和轨道的侧面金属剥落或轮缘向外变形，甚至脱轨造成重大人身伤亡和设备事故。

The temperature field of a kind of road wheel's rubber flange was calculated with finite element analysis software ANSYS,and the effect of five parameters on the highest temperature of wheel flange was analyzed.

用ANSYS有限元分析软件计算了某型负重轮橡胶轮缘的温度场，定量分析了5个参数对轮缘最高温度的影响。

Road wheel rim rubber tanks tanks moving as an important component of the flange for rigidity and strength of analysis, can improve the weight-bearing rubber wheel rims in their work performance.

坦克负重轮橡胶轮缘作为坦克行进中的重要部件，对该轮缘进行刚度和强度分析，可以提高负重轮橡胶轮缘在工作中的性能。

On tubeless tire s, do not use tire irons to force the beads away from the rim flanges; this could damage the rim seals on the beads and cause an air leak.

1维修无内胎轮胎时，不能使用撬棒强行把轮缘从轮辋上拆卸下来。这样容易损坏轮缘上的轮辋止口，并造成空气泄漏。
