The calculation of imbalance response plays an important role in the dynamical analysis of rotor-bearing system, the FEM is one of the methods that can calculate the dynamical response, and the ANSYS is a large finite element analysis software. This paper studies on the rotor test bed, and the supporting condition of the rotor-bearing is set in reason with the help of ANSYS. Dynamic parameter such...
This paper presents the dynamic modeling of a bimodal piezoelectric ceramic motor by use of the finite element method. The extended Hamilton's principle is utilized for formulating the dynamic equation of motion, and the Lagrange multiplier method is used to model the contact dynamics between the resonator beam tip and the rotor. The numerical simulation result is approximate to the practical experimental...
