| 摘 要： | 简要分析了边界元法在梁类结构振动仿真研究中的优点和缺点，应用边界元法对矩形梁弯曲振动进行了固有振动仿真分析，当梁的弹性常数改变时，结构的固有振动频率会相应地改变，为通过改变结构材料参数来改善梁结构的动力学性能进行理论探索．

| Abstract: | The 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. |
