摘要: 第一部将Holzer氏法修改后可求解在任何端部情况下直串系统的固有频率;第二部分针对直串系统特征矩阵具有三对角线和对称的特点,提出求解受迫振动稳态解的追赶方法。

Abstract: The paper is concerned with two parts of the straight-through system with many degrees of freedom.The first is the modification to the method due to Holzer by the auther to find the natural frequencies not only for the rotating system but also for the rectilinear system with any, end condition. These operations can be clearly seen in the flow diagram of fig, 5.In the second part, owing to the tri-diagonal and sysmetrical form of the characteristic matrix, a chase method is proposed by the author to calculate, the steady state response.
