Research on BEM Simulation of Bending Vibration of Beam Mechanism

The strong points and shortcomings of vibration simulation research on beam parts between finite element method and boundary element method were briefly analyzed. Beam parts are important mechanical structure components which are used widely in engineering machines. The dynamic simulation and analysis of bending vibration of a rectangle beam mechanism have been simulated with the BEM matlab program. While the elasticity constant E of the beam was invariable, the width-height ratio of the cross section was changed ; then the inherent frequencies of the beam mechanism would change accordingly. Therefore academic exploration can be carried on through the dynamic performance improvement of the beam mechanism by amending its parameters.
