一种齿轮箱信号分析与故障诊断系统

Signal Analysis and Fault Diagnosis System of Gearbox

介绍了一种齿轮箱信号分析与故障诊断系统，该系统以“三谱二时域”综合诊断法为理论基础，并将共振解调技术应用于齿轮箱故障诊断中。讨论了该系统的原理、硬件结构和软件系统，并运用该系统对一齿轮断齿故障进行了诊断，结果表明该系统是有效的。

A system of gearboxs signal analysis and fault diagnosis is introduced.The system based on 'Three Spectrums and Two Time Domains' synthetic method and resonance demodulation method is used in the gearboxs fault diagnosis sytsem.The theory,hardware and software are discussed.A broken fault in gearbox is diagnosed by the system and the result shows that the system is scientific and effective.
