铁轨无损检测平台设计
Design of rail nondestructive testing platform
摘要
进入二十一世纪，我国经济飞速发展，工业化程度大大加深，轨道交通由于其载力大，速度快，占地面积小等特点，契合我国的人口密度和基本国情，逐步发展成了我国的主要交通运输方式，也是我国基础建设的重点项目。铁路受到车辆车轴上的速度和载荷的恒定增加以及焊接铁路轨道中的应力的恒定增加的影响而产生缺陷，如果不采取恢复措施，缺陷可能恶化，最终可能发展成完全的轨道断裂，这是造成列车脱轨的主要原因。所以研究一种高效，准确，经济的铁轨探伤手段势在必行。
本课题主要研究铁轨无损检测平台，利用无损检测技术对铁轨进行损伤检测，其主要设计内容针对无损检测现状，无损检测的发展等内容的研究：对无损检测平台的结构进行方案和总体设计，计算与确定，设计方案提高无损检测质量。
最后，绘制无损检测平台平面图与三维模拟图，对无损检测平台进行分析，撰写课题说明书。

Abstract
In the 21st century, China's economy has developed rapidly, its industrialization has deepened greatly, and rail transit has gradually developed into China's main mode of transportation due to its large loading capacity, fast speed, and small land area. It is also a key project in China's infrastructure construction. The railway is affected by the constant increase in speed and load on the axle of the vehicle and the constant increase in stress in the welded railway track. If no recovery measures are taken, the defect may deteriorate and may eventually develop into a complete orbital fracture. This is the main reason for the derailment of the train. Therefore, it is imperative to study an efficient, accurate and economical means of track detection.
This topic mainly studies the non-destructive testing platform for railroad tracks, and uses non-destructive testing technology to detect damage to railroad tracks. Its main design content is based on the current status of non-destructive testing and the development of non-destructive testing. The structure of the non-destructive testing platform is studied: the scheme and the overall design are carried out. Calculation and determination, design scheme to improve the quality of nondestructive testing.
Finally, draw the floor plan and three-dimensional simulation map of the nondestructive testing platform, analyze the non-destructive testing platform, and write a project description.
