摘要
以滚动轴承故障诊断的共振解调原理为基础,提供了一种以C8051F340单片机为核心的智能化轴承故障诊断仪的研制方案。由模拟硬件电路获得所需的轴承振动信号之后,通过USB接口和VB 6.0程序实现与PC机联机的9通道数据采集电路,将模拟信号传送至上位机并使用上位机程序进行后续频谱分析及处理,判断轴承的运行状况;最后,通过实验的方式验证了共振解调原理与本诊断仪的正确性和实用性。
The development of intelligent bearing fault diagnosis instrument based on C8051 F340 and the principle of resonance-demodulation is provided. The necessary beating vibration signals were obtained by the analog hardware circuitry. A data acquisition device which has 9-channels was designed. This data acquisition device can transmit the analog signals which are produced by hardware circuitry to PC; the PC applications software was designed to determine the operational status of hearings according to spectrum analysis and procedures processing. The bearing fault diagnosis instrument has been used in rolling bearing vibration testing laboratories, the correctness and practicality of this system has been validated.
