摘要
本文讨论了均布载荷作用下圆薄板在非线性弯曲静平衡构形附近的微幅自由振动。静平衡问题采用文献［２］给出的精确解，在此基础上用修正迭代法求解，得到了其固有频率－载荷特征关系。
his paper deals with the small free vibration in the vicinity of the static equilibrium configuration of nonlinear bending of a circular thin plate under static uniformed load. Based on the exact solution of the static nonlinear bending problem which is given in reference [2],the characteristic relation between the natural frequency and the static load is gained by means of the modified iteration method.
