The Design of Train Bearing Signal Analysis System
Abstract：During the development of high speed train, there are all kinds of faults in the train running, and the bearing fault is a vital part of the train safety.. Train bearing signal analysis is through to digital signal processing to the bearing vibration signal analysis of a discipline, mainly for bearing fault occurrence components take the digital signal analysis and processing. Matlab is a high-level software for data analysis, data processing and data calculation.. In the Matlab, there exist many functions that analyze and process the data, and can quickly and simply complete the analysis and processing of the digital signal and visualization of data.. In order to facilitate, we use the GUI interface module in Matlab to achieve the unity of the common processing method of signal to one operating interface.. The system is simple and easy to understand.. In the actual operation of the keyboard only keyboard input of the data, the rest of the function simply by clicking the mouse to complete. The main function of the system: time domain analysis, frequency domain analysis, envelope analysis and characteristic frequency calculation of the signal of the train bearing. 源￥自%六:维;论-文'网=www.lwfree.cn
