Analysis of Torsional Vibration Inherent Characteristics of Gear Shaft
The transfer matrix method and the finite element method are used to calculate the torsional vibration inherent characteristics of the gear shaft of the motor-driven feed pump.The transfer matrix method needs to establish the multi-segment concentrated mass model of the shafting system.The finite element method is used to establish the model of the shaft system with gears by using ANSYS software.The gears are set using the matrix unit Matrix27.The results of the two methods are compared to ensure the accuracy of the model Consider the gear shaft with the role of bending and torsion obvious,based on the established nonlinear model of gear-shaft system,the differential equation of gear kinematics is deduced,and the stiffness coupling in Matrix27 is modified by obtaining the stiffness matrix.The final calculation results show that the gear-shaft system has a new frequency Appears,and some frequencies and some of the frequency is not coupled,there will be some changes.
