| 摘 要： | 提出了用GDQM与有限元相结合的一种结构分析的新方法，并用此方法对中心带有弹性安置质量的薄圆板的轴对称自由振动进行了分析。本方法能同时发挥GDQM精度高、计算量小、收敛快和有限元法十分灵活的优点，使两种方法得到有机结合，其计算结果与现有文献的结果吻合很好，证明了本文方法的可行性。

| Abstract: | The generalized differential quadrature method (GDQM) developed recently is an efficient method in structural analysis, but has some limitations. The finite element method (FEM) is a conventional numerical method, but requires great calculation work. GDQM and FEM are combined together to analyze the transverse vibration of circular plates with an elastically mounted mass. This combination is a new way that has never been proposed before to solve the problems of complex domains in structural analysis. It is a quick, efficient, accurate and flexible numerical method with both the advantages of GDQM and FEM. Comparison with the existing literature has proved that the results obtained by this method are very good. |
