| 摘 要： | 建立了一种直接利用传递函数对分叉结构进行模态综合的方法。传统的方法一般都需要对大矩阵进行求逆运算,而此方法只涉及分叉结构结合部的传递函数矩阵的求逆,因此求逆计算量很小,特别是当直接采用传递函数的测量值进行模态综合时,就更体现出它的优越性。

| Abstract: | This paper established a modal synthesis method directly using transfer functions for furcated structural system. Conventional method usually invert matrix for large matrix. Proposed approach can reduce the calculation amount of inverting matrix a lot. Because it only needs inverting transfer functions matrix for junction of furcated structural system. The method is presented to show the advantage of the modal synthesis, particularly use the tested transfer functions matrix |
