机电一体化系统设计论文 题目：铁路车辆轮辋探伤机的机电一体化设计 学号： 姓名： 专业：机械工程 导师： 学院：自动化学院 2015年1月30日  摘 要 随着世界高速铁路的迅猛发展，为适应国民经济发展，满足广大人民的需求，我国铁路事业蓬勃发展。近年来，我国铁路行车速度不断提高，这就要求对机车车辆走形部件进行严格而精密的检修与监控。尤其是高速动车组的开行给铁路安全检测部门提出了新的考验。 目前，德国、法国等铁路发达国家均设计研发了先进的超声车轮探伤设备，我国也自主研发了移动式轮辋轮辐探伤系统，该设备采用先进的相控阵超声探伤技术和常规探伤技术，对各型动车组车轮进行在线的轮辋轮辐探伤，实现对各类疲劳缺陷及材质缺陷的检测。但检测结果中缺陷的定位，还需现场操作员手动拖动标定框实现，这就不可避免的造成人为误差，限制了探伤效率，难以适应我国高速列车迅猛发展的要求[1]。 本文设计的系统采用底下卧式紧凑型机身，整个设备处于轨道面以下，同时在不工作室盖上盖板即可使轮对通过。能够自动实现轮对的进轮及缓冲，出轮功能等。系统设计分为机械系统，控制系统与伺服系统几部分。采用机、电、液和微控系统，可以比较容易的实现轮对的进出轮[2]。 关键词 机械 控制 设计 轮对 ABSTRACT With the rapid development of high-speed railway in the world， to meet the economic development， to meet the needs of the majority of the people， Chinas railway industry to grow. In recent years， Chinas railway traffic speed continues to increase， which requires to take shape parts for locomotives strict and precise maintenance and monitoring. Especially CDB EMU to railway safety inspection department proposed a new test. Currently， Germany， France and other countries are designed railway development of advanced ultrasonic wheel inspection equipment， our country has independently developed the rim spokes mobile inspection system， the device uses an advanced phased array ultrasonic flaw detection technology and conventional testing techniques for each EMU wheel rims spokes online testing， to achieve the detection of various types of fatigue defects and material defects. But the location of defects in the test results， the need to manually drag the calibration site operator to achieve box， which inevitably cause human errors， limiting the detection efficiency， difficult to adapt to the rapid development of Chinas high-speed trains. This design of the system uses a compact body under the horizontal， the entire device is below the orbital plane， while the studio is not covered by the cover can make wheel. Can automatically feed wheel and buffer wheel， and a round function. System design is divided into mechanical systems， co
