The dynamic behavior of the rotor-bearing system of the slider-crank mechanism was studied in this paper. Based on the finite element method, a model of the rotor-bearing system was developed. The calculation results of the numerical simulation demonstrated that dynamic response of the shaft depended on both the bearing stiffness and the dynamic property of the slider-crank such as rotor rotate speed.
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...
