BEM Simulation of Natural Vibration of Large-type Beam Structure Based on Matlab

AbstrcatThe strong points and shortcomings of vibration simulation research on the type of beam parts with boundary element method are analyzed briefly. The dynamic simulation and analysis of bending natural vibration of the rectangle beam structure have been processed with the boundary element method. While the elasticity constant E of the beam is changed, the natural frequencies of the beam structure should change accordingly. So academic exploration is done by improvingthe dynamic performances of the beam structure with amending the parameter E ofthe structure.
