| Abstract: | The measurement and spectrum analysis are taken on the process parameters of the fan, such as torsional vibration, torque and bearing vibration, under different conditions to find out the root causes of fan diaphragm coupling fracture and intermediate shaft crack. With the analysis, it is determined that the fan frequency conversion operation causes the torsional vibration and it is the root cause for the damage of the shafting system. Based on the fan shafting system modeling and simulation, the causes and solutions are figured out and suggestions for improvement are put forward. |
