基于DSP技术为机车轴承设计故障诊断监控系统(中文2400,英文1700字)
摘要
滚动轴承是机车运行组件的关键部件之一,因为它直接关系到机车的性能和安全。在本文章中,监控系统为机车轴承基于DSP TMS320LF2407A的设计。这个系统使用振动分析方法来诊断滚动轴承的故障。它是在全面的共振解调和快速傅立叶变换技术基础上,采用”相关的方法”来处理FFT的结果。它有效的提高了轴承故障监控系统的反应特性,灵敏度,辨别和测量精度,它可以预测火车头运行中的故障和监测瞬态故障。

Design of Fault Diagnosis Monitor System for the Locomotive Bearings Based on DSP Technology
Abstract
The rolling bearing is one of the key parts of the locomotive running components, because it condition is directly related to the performance and safety of locomotive. In this paper, the monitor system for the locomotive bearings based on DSP TMS320LF2407A is designed. This system diagnoses the rolling bearing fault using vibration analysis method. It is based on comprehensive resonance demodulation and fast Fourier transform technique, and it adopts "related methods" to handle the result of the FFT. It effectively improves the response characteristics, sensitivity, differentiate and measurement accuracy of the bearing failure monitor system, and it can fulfill the monitor and prediction of the transient fault in the course of the locomotive running.
