| Abstract: | The damage of a train bearing is a main cause that endangers the safety of a moving train. How to measure the size of the damage is the key problem that needs to solve in the developing of high speed or burden trains. This paper presents a new measuring method of on-line detecting the damage of a train bearing with the acousti resonance demodulation technology, which can realize the on-line ration measuring of a train bearing damage. This measuring system is composed of sound sensors, data collecting system, resonance demodulation circuit and signal processing, etc. The spot experiment shows that the result is satisfied when detecting the damage of a train bearing. |
