摘要
介绍了精细传递矩阵法无需对微分方程进行求解,只需按照迭代公式进行计算,就可以得到所需要的传递矩阵,推导了刚架在面内自由振动时的精细传递矩阵,通过实际的计算,证实了该方法是一种具有较高精确度且简便易行的方法。
Precise transfer matrix method is not need to solve the differential equations,just following the iterative formula,the necessary transfer matrix can be get.The precise transfer matrix on free vibration of a frame in plane is advanced in this paper.Practical calculations show that this method is accurate,simple and practicable.
