摘　　要：用广义微分求积法(GDQM)对受弹性约束的变厚度圆板的自由振动进行了分析,采用Crout分解法解求了积方程,并同其他方法进行了比较,证明了GDQM的灵活性和精确性。The generalized differential quadrature mathod （GDQM） is applied to the vibration analysis of circular plates with variable thickness. The Crout method is used to solve the quadrature equations. Comparing the results of the GDQM with other methods, it is proved that the GDQM is very accurate and flexible.

关 键 词：GDQM 圆板 变厚度 自由振动
