门式刚架面内振动特性分析的精细传递矩阵法
Precise Transfer Matrix Method for Vibration Characteristics Analysis of The Steel Frame in Plane
【摘要】 精细传递矩阵法无需求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。本文推导了门式刚架在面内自由振动时的精细传递拒阵。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。
【Abstract】 Precise transfer matrix method is no need to solve the differential equations,just following the iterative formula,the necessary transfer matrix can be get.The transfer matrix on free vibration of a frame in plane and out plane is advanced in this paper.Practical calculations show that this method is accurate,simple and practicable.
