通过在动车组转向架的轴箱、构架和车体上安装加速度传感器,结合动车组的实时运行速度和运行区段位置,利用网络化结构,同时检测各转向架在直线区段高速运行时有关部位的振动数据,利用计算机对实测的数据进行比较分析判断动车组运行动力学性能,从中找出异常数据即异常转向架,提升动车组运行的安全可靠性,使动车组运行安全技术更上新台阶。从而进一步改变目前通过人的认知感觉来评判动车组的技术状态问题和发生异常后才通过移动检测设备对动车组的性能进行检测的被动做法。同时,在检测数据积累与分析的基础上,研究动车组动力学性能的变化规律,构建一套动车组动力学性能跟踪监测评价系统,使得随车机械师、司机等有关人员可以实时掌握动车组的运行性能情况,对动车组运行过程中的问题作出及时果断正确处理;帮助技术管理人员,能够根据动车组的实际运行性能,更加科学合理安排动车组的计划修和状态修;进一步促使动车组运行管理部门能够及时掌握动车组的技术状态,为管理决策提供依据。
Through the installation of acceleration sensors on axle box, frame and body of EMU bogie, combined with the real-time running speed of EMUs and the position of the running section, the network structure is used to detect the bogies involved in the high-speed running of the straight section Part of the vibration data, the use of computer data measured comparative analysis to determine the EMU operating performance, to find out the abnormal data that is abnormal bogies to improve the safety and reliability of EMU operation, EMU operational safety technology to a new Stairs. So as to further change the passive state-of-the-art approach of judging the technical status of the EMU through the cognitive perception of the people and detecting the EMU’s performance through the motion detection equipment only after the abnormality occurs. At the same time, on the basis of the accumulation and analysis of test data, the change law of dynamic performance of EMUs is studied, and a set of EMM tracking and evaluation system is established. With the help of mechanics, drivers and other relevant personnel, Of the operating performance of the EMU in the course of the operation to make timely and decisive problems in the right handle; help technical managers, according to the actual operation of EMU performance, more scientific and rational arrangements for the EMU’s planned repair and condition repair; to further promote the EMU Operation management department can grasp the technical status of EMU in time and provide the basis for management decision-making.
