Acoustic Emission Signals Characteristics of the Giant Wheel Main Spindle

摘要: 大型观览车不仅是游乐园的标志，而且是城市的标志。针对大型观览车主轴系统难以拆卸的特点，通过试验模型，模拟了主轴运行过程，采用声发射仪器获取了主轴系统运行过程中的声发射信号。通过分析声发射信号，初步得出了主轴运行过程中声发射信号的规律特征，包括参数特征和波形频谱特征。

Abstract: Giant wheel, as one type of largescale amusement device, is not only a symbol of the amusement park, but also of the city. As one important part of the giant wheel, the main spindle is difficult to be disassembled. In this paper, the simulation model of the giant wheel was designed and manufactured, in which the operation process of the main spindle could be simulated. The acoustic emission(AE) technique was used to monitor the test process. The acoustic emission signals characteristics were analyzed, including AE parameter distribution features and wave spectrum characteristics.
