Magneto-elastic nonlinear non-axisymmetric resonance is investigated for a rotating annular plate in a double-direction magnetic field. According to transverse and longitudinal magneto-elastic non-axisymmetric vibration equations of the thin annular plate, and considering the influence of the static load term, non-axisymmetric vibration differential equations by combined parametric and forced excitations are obtained through application of the Galerkin method. Then, the method of multiple scales is applied to solve differential vibration equations. By numerical computations, the influence of magnetic induction intensity, inner and outer diameters, excitation and radial forces on transverse and longitudinal resonance characteristics are analyzed.
Abstract. Aiming at the need of multi-objective optimization design of the common beam in engineering, this paper optimized the beams’ carrying capacity and anti-vibration ability based on optimization design platform of Isight, which integrated ProE and Ansys software. Through automatic iteration of the beam’s 3D modal data and simulation results, one ideal optimization solution can be obtained by using NLPQL algorithm. Compared with initial design, optimization Results’ performance parameter improved markedly. This standard method and steps can be promoted to engineers, which involve beam’s finite element analysis and design optimization.
