| 摘 要： | 给出圆板弹性支承的传递矩阵,并用计算机代数语言编写圆板环形条元及支承元件的传递矩阵,通过试验模态分析,确定圆板轴对称振型及频率,将该频率代入含待识别支承刚度的传递矩阵法中去,就可直接识别其刚度,并通过实验验证了此法的有效性。

| Abstract: | The transfer matrix of annular strip and supporting element of a circular plate can be com- posed by computer algebra language.By means of experimental model analysis,the axial symmetry modal and natural frequency is determined.This frequency is brought into the transfer matrix method,which contains unknown quantity of the supporting stiffness.Thus the stiffness can be identified directly.The effectiveness of this method has been proved by experiments. |
