“听诊器”原理及其在机械故障诊断中的应用

Principle of Stethoscope and Its Application in Diagnosis of Mechanical Fault

从听诊器上得到启发,使用类似的装置测得的声音信号可以有效地屏蔽外界噪声,得到较为纯净的信号,为确诊机械故障提供有力的数据支持。

Imitating the principle of stethoscope ,the similar instrument can be used to collect sound signals coming from machines. In this way,the outside noises can be efficiently shielded and the pure signals can be collected comparatively. Also the signal received in this way can be a strong support for making right diagnosis of mechanical fault.
