【摘要】：随着工业化的进程,机械系统的运行可靠性越来越受到了人们的重视。牵引电机滚动轴承是电机设备中常用的部件,并且是故障率非常高的零部件之一,所以对牵引电机滚动轴承的故障诊断就显得十分重要。本文就是利用共振解调技术对滚动轴承进行故障诊断。共振解调技术是近几年逐步发展起来的一门新技术,这种方法简单,易实现,加上很好的可靠性,使得共振解调技术在故障诊断领域有了广阔的发展前景。本文在理论研究共振解调技术的基础上,进行了实际的实验论证。以北京交通大学NTN轴承试验台为试验平台,利用奥地利DEWETRON公司的数据采集设备DEWE-211进行实时的数据采集,其良好的数据采集性能也是本次试验能够成功的基础。最后在丹麦BK公司的数据分析软件PULSE的基础上,开发了一套软件,进行后期的数据分析处理,最终验证了软件法共振解调技术的可行性。
[Abstract]:With the process of industrialization, more and more attention has been paid to the operation reliability of mechanical system. The rolling bearing of traction motor is a common component in motor equipment, and it is one of the parts with high failure rate, so it is very important to diagnose the fault of traction motor rolling bearing. In this paper, the resonance demodulation technology is used to fault diagnosis of rolling bearings. Resonance demodulation technology is a new technology which has been gradually developed in recent years. This method is simple, easy to realize, and has good reliability, which makes the resonance demodulation technology have a broad development prospect in the field of fault diagnosis. On the basis of theoretical research on resonance demodulation technology, this paper has carried on the practical experiment demonstration. Taking the NTN bearing test-bed of Beijing Jiaotong University as the test platform, the real-time data acquisition is carried out by using the data acquisition equipment DEWE-211 of Austria DEWETRON Company. Its good data acquisition performance is also the basis for the success of this experiment. Finally, on the basis of the data analysis software PULSE of Denmark BK Company, a set of software is developed to analyze and process the data in the later stage. Finally, the feasibility of the software resonance demodulation technology is verified.
