| 摘 要： | 本文发展了适用于捆绑火箭的各向耦合自由振动的传递矩阵法，并对捆绑结构的处理难点－捆绑边界条件的处理给出了理论的说明，因而本方法是适用于各种捆绑结构振动模态分析的通用方法，对捆绑火箭１／１０比例模型进行计。算比较表明，传递矩阵法是适合于捆绑结构模态计算的方法。

| Abstract: | This paper presents a development of the general matrix-Holier method for predicting the free vibration modes of full-coupled clustered launch vehicles and gives a theoretical illusration for the clustered boundary condition which are the most difficult to be dealt with.The problem is so formulated that it can be adapted to the analysis of vibration modes in various types of clustered structures.A calculation of the full-coupled vibration modes of a 1/10 scale.rocket model is conducted by using this method.Compared with the test results,it shows that this method is adapted to calculating modes of the clustered structures. |
