轨道平顺性论文：高速铁路轨道平顺性测量相关技术问题的研究【中文摘要】目前,中国已投入运营的高速铁路里程已达到7000多公里,同时还有1万余公里高速铁路(时速250公里以上)在建。高速铁路行车速度快,要求轨道的平顺性好。为了确保轨道的平顺性满足高速行车的要求,目前的通用方法是在精测网的控制下,通过轨检小车实测轨道平顺性的各项参数,并与设计参数进行比较,再通过轨道精调使轨道的平顺性各项参数满足设计要求。衡量轨道平顺性的参数有哪些,以及如何测量与计算,是轨检小车设计与制造的关键技术。因此,本文针对轨道平顺性测量的相关技术进行研究,具有现实的意义。本文首先研究传统轨道平顺性各项参数的测量原理与计算方法,接着详细研讨现代轨道平顺性各项参数的测量方法和计算模型,主要包括德国和中国对轨向及高低这两个重要参数的评价标准和计算方法。最后根据所推导的数学模型和计算方法计算了一段轨道实测数据,并与某轨检小车的计算结果进行比对,以验证所推导数学模型和计算方法的正确性和可行性。本文的主要学术贡献在于以下两点：1)介绍了如何通过CP控制网下的实测坐标关联轨道的设计里程及其设计参数,以及如何根据轨道的实测坐标计算轨道中心线的坐标；2)通过比较德国和中国轨向和高低的计算方法与结果,认为两种方法具有各自的优势,可以互补,为了充分真实地反映轨道的轨向和高低,轨检时应该使用两种方法进行评价与分析。【英文摘要】At present, China having been put into operation high-speed railway mileage has reached more than 7000km, as well as ten thousand kilometers of high-speed railway (250km per hour or more) under construction. High-speed railway traffic speed, requiring Track Regularity better. In order to ensure that the ride track meet the demands of high speed traffic, currently is the general way in precision measuring network control, by track inspection car track ride the parameters measured, and compare to design parameters and fine tuning makes the track by track by ride the parameters meet the design requirements. Measuring rail ride what are parameters? How these parameters and the definition of measurement and calculation? Is key to design and manufacture of rail detecting car technology, therefore this article related to rail ride comfort measurement technique to study with real-world significance.This first study on the traditional track measuring principle and calculation method of ride comfort parameters, Went on to discuss in detail modern rail ride comfort measurement method of ride comfort and track various parameters of the calculation model, Rail that is involved in important parameters both high and low orbit and to ride Germanys standard and calculation methods and standards in China and its calculation method, The last calculated based on the mathematical model and calculation method for the derivation of the parameters of the section of track test track ride, And than on the results of a calculation of track inspection car, to verify the correctness and the feasibility of the mathematical model and calculation method of derivation.Main scholarly contribution is this article the following two points:1) Describes how to CPIII measured under control network coordinates associated with mileage of track design and its design parameters, and how the track measured coordinates calculation of coordinates of the track centre line;2) By comparing Germany and alignment and high and low calculation method and results in China, the two methods have their own advantages, can complement one another, in order to fully truly reflect the track alignment and high and low, track inspection should be used for evaluation and analysis of two methods.【关键词】轨道平顺性 轨检小车 高速铁路 精度【英文关键词】Track Regularity Railway Inspection Instruments High-speed railway Accuracy【目录】高速铁路轨道平顺性测量相关技术问题的研究摘要6-7Abstract7第1章 绪论10-161.1 引言101.2 轨道平顺性测量发展概况10-111.3 无砟轨道平顺性测量现状11-131.4 轨道控制网(CP网)简介13-141.5 本文的主要研究内容及意义14-16第2章 轨道平顺性各项参数的定义及其传统的测量方法16-262.1 轨距16-172.2 水平/超高17-182.3 正矢/轨向18-202.4 高低20-212.5 扭曲21-222.6 里程222.7 线路中线的三维坐标222.8 轨检车测量轨道的各项平顺性参数22-26第3章 轨检小车测量轨道平顺性参数的原理研究26-433.1 轨检小车的工作流程263.2 轨检小车检测轨道平顺性各项参数的原理26-433.2.1 轨距的检测原理26-273.2.2 水平/超高的检测原理27-293.2.3 轨向的中波和长波不平顺检测原理29-323.2.4 高低的检测原理32-333.2.5 扭曲的检测原理33-363.2.6 线路里程的测量原理363.2.7 线路中线点三维坐标测量原理36-43第4章 轨检小车测量轨道平顺性各项参数的相关数据计算及分析43-544.1 线路中线点坐标计算与分析43-444.2 轨距和轨距变化率计算与分析44-464.3 水平/超高计算与分析46-474.4 轨向德国检测方法的计算及其与中国检测方法的比较47-504.5 高低德国检测方法的计算及其与中国检测方法的比较50-524.6 扭曲计算与分析52-54结论与展望54-55致谢55-56参考文献56-60攻读硕士学位期间发表的论文60-61附表一 线
