| 2. | Image processing of near - infrared rail abrasion detection system 近红外钢轨磨耗检测中的图像处理 |
| 3. | At last through the analysis of the result of the measurement this paper points out the focal point that needs to be improved 最后,本文通过编写软件系统实例对钢轨磨耗自动测量的执行过程进行了跟踪,并对软件运行结果做了初步的分析,指出系统进一步改进的设想。 |
| 4. | Side wear of rail on curves is a normal phenomenon in railway engineering . a great quantity of rail wear results in decreasing rail life in use and increasing railway transportation costs 钢轨侧面磨耗是工务工程中普遍存在的问题,大量的钢轨磨耗缩短了钢轨的使用寿命,增加了铁路运营成本。 |
| 5. | This paper has introduced the developing background of the automatic measurement system for rail - wear and the present situation of the automatic measurement technology for rail - wear firstly , point out the necessity of developing the automatic measurement system for rail - wear 本文首先介绍了钢轨磨耗自动检测系统的开发背景以及钢轨磨耗检测技术的研究现状,指出开发磨耗自动检测系统的必要性。 |
| 6. | So , it is very important for the maintenance security of the rail and railway to measure rail - wear precisely and speedily and this problem is still an important research subject of which the ministry of railway in every nation has to be in face 钢轨磨耗是否超限直接决定钢轨是否被更换或打磨,因此,精确地测量出磨耗值对于钢轨的维护及行车的安全是非常重要的。如何精确而高效地测量出钢轨磨耗一直是国内外铁道部门的一个重要的研究课题。 |
| 7. | Recently , with the development of railage , passenger transport , freight and the density of train have increased mostly . it results in rail - wear day after day , especially the side rail - wear . so the ministry of railway has been taking the situation of rail into account greatly to insure train and rail safely 近年来随着铁路重载运输的大力发展,客货运量和行车密度大幅度增长,从而导致钢轨磨耗日益严重,尤其是曲线钢轨的侧面磨耗急剧上升,因此铁路工务部门十分重视对钢轨伤损情况的检测,以确保行车的平稳性和安全性。 |
| 8. | Last , the reliability of 50kg / m - rail and 60kg / m - rail is calculated by using the method combing the mote - carlo imitation with the finite element method . on the basis of the calibration method , the objective reliability index of the steel rail is recommended , and the problems of the present standards of the rail - wear limits are pointed out , and then the rail - wear limits are discussed 最后,采用有限单元法与蒙特卡罗法相结合的方法对50kg m轨和60kg m轨的可靠度进行了计算,根据“校准法”的思想得到了钢轨目标可靠指标的建议值,指出了现行钢轨磨耗标准所存在的问题。 |
