七十年代国外出现的传递矩阵和有限单元组合法(即FETM方法)规定:传递元件的始端线和终端线的节点数目必须相等,这就使得该法仅适用于形状较简单的板壳的振动分析。本文克服了这一限制,建立了始端线和终端线节点数目不等的一种新的传递元件,提出了“广义传递矩阵和有限单元组合法”,此法便于分析复杂形状平板的振动。最后,用算例证明了此法的有效性。 The transfer matrix and finite element combination method (FETM method) abroad appeared in the seventies states that the number of nodes of the beginning and the end of the transfer element must be equal, which makes the method suitable only for the vibrations of the simple-shaped shell analysis. This paper overcomes this limitation and establishes a new transfer element with a different number of beginning and ending nodes. The generalized transfer matrix and finite element combination method is proposed, which can be used to analyze the vibration of complex shape slabs. Finally, an example is given to show the validity of this method.
