Investigation on Acoustic Emission Characteristics of Steel Structure of Amusement Device

Steel structure is the foundation of the amusement device. The health status of the steel structure is crucial to the safe operation of amusement device. In order to realize the overall monitoring of the steel structure, the application of acoustic emission technique for online testing on a disco turntable has been studied. The attenuation regularity of AE signals and the sound velocity of the steel structure were tested. AE signals of the steel structure were collected during the normal operation of the disco turntable. The AE characteristics including AE parameter features, spectrum features, and location features were analyzed. The results of this study indicated that the AE technique has great potential for the condition monitoring and safety evaluation of the steel structure of amusement device.
