ANSYS-based Model Analysis on Torsional Vibration of Draught Fan Shaft
Draught fan is the main auxiliary equipment in the thermal power plant.With the increasing of the capacity and dimensions of the auxiliary equipment,the torsional vibration of the shafts becomes serious.This paper founds a mathematical model about the shafts,and a finite element model is built by applying the finite element analysis software ANSYS.By changing the wheel dimensions of the model,such as the wheel diameter,the paper calculated the natural frequencies and the vibration mode of the torsional vibration of the shafts.Results showed that the natural frequency will decrease as the wheel diameter becomes large,and the change of vibration mode is not so obvious.This model is simple and the calculation results are reliable.The method is helpful for engineering application of the design of the rotor.
