| 摘 要： | 在各种复杂的分支传动扭振系统中,由于计算工作量大而对计算机内存及速度提出了一定的要求。本文比较了三种常用的计算扭振固有频率的方法(霍尔茨法、传递矩阵法和直接法),认为采用基于传递矩阵的直接法计算更简单、明了。因其不需要求解结点方程,故不会产生前两种方法中出现的方程奇异性问题。文中结合一个前后分叉的七分支系统,介绍了直接法的实际运用。

| Abstract: | In complex branched transmission systems,the calculation of the torsional vibration demands the computer to have more memory and fast speed.This paper compares the three methods of torsional vi- bration calculation(Holzer,transfer matrix,and direct method)and indicates that the direct method is the simplest and clearest.The problem of equation singularity does not exist here because there is no need to find the mode equation.The application of the direct method in calculation a 7-branched sys- tem of the head-tail branch is also presented. |
