TRANSMISSION SHAFT CRACK DETECTING SYSTEM

摘要

A transmission shaft crack measuring system is provided to improve reliability of measurement results without influence of surrounding environment by comparing natural frequencies of a reference transmission shaft and a measured transmission shaft to determine a crack. A transmission shaft crack measuring system includes a controller(1), a signal processing module(2), an acceleration sensor(5), and an impact hammer(6). The controller has a program to analyze frequency of a transmission shaft(W). The signal processing module has a signal processor(4) and an A/D converter(3). The signal processor excites the frequency signal while amplifying the frequency signal through a speaker. The A/D converter converts the signal processed by the signal processor and transmits the converted signal to the controller. The acceleration sensor transmits the frequency of the transmission shaft to the signal processing module. The impact hammer gives impact on the transmission shaft to generate vibration.
