摘要
本文通过实测弹性地基梁的固有频率 ,以传递矩阵法为基础 ,利用计算机代数语言 ,导出以支承刚度为未知数的高次方程 ,从而识别出地基系数 ,并通过实验验证该方法的正确性。
By means of the measuring the natural frequencies of a beam on a elastic foundation together with the transfer matrix method and the computer algebraic language,the paper deduces the high order equation,which contains unknown quantity of the stiffiness of supports.This method,the validity of which has feen verified by experiments,can be applied to identifying the foundation coefficient.
