ENGINES having shaft systems with one or more than one pair of twin-branches may suffer from torsional vibrations of an asymmetrical nature at the branches due to superposition of a "parallel pattern" on a "symmetric pattern". The asymmetry will "change side" according to the operating load and speed of the aggregate. The main

当某个发动机轴系具有一对或多对双生分支时,在分支处会产生不对称的扭转振动振型,即此处所说的偏振。它是由于所谓“平行振型”与“对称振型”叠加的后果。当机组的运转工况改变时,此“偏振”会“换边”。影响“偏振”和振动强度的主要因素有: ·干扰力矩的简谐次数。·多排式发动机每横列同曲柄各缸的发火顺序; ·主付系统同次干扰简谐的相位差; ·频率比——它代表干扰频率同主或付系统自振频率之比本文对上述“换边”及偏振强度进行了理论分析及实测验证。为此,曾有意安排几种付系统加重块调频,从而得出所需大量数据,以说明问题。

The transfer matrix method is usually adopted for calculating critical speeds, principal modes and the unbalance response of multi-span shafts. However, due to errors introduced by limited word capacity of the computer, the calculated principal modes may suffer serious distortion and the residual moments may jump irregularly from certain rotating speeds onward, so that the calculation would often result in failure.

The transfer matrix method is usually adopted for calculating critical speeds, principal modes and the unbalance response of multi-span shafts. However, due to errors introduced by limited word capacity of the computer, the calculated principal modes may suffer serious distortion and the residual moments may jump irregularly from certain rotating speeds onward, so that the calculation would often result in failure. In this paper, the causes producing the above mentioned phenomena are analysed and a correction matrix method is presented in order to compensate for the loss of significant figures. When the correction matrix is used, one can obtain more accurate and reasonable results in the calculation of principal modes and residual moments. In spite of limited computer word capacity, it is still possible to successfully calculate the higher frequencies and principal modes of shaft systems with even greater number of spans by the transfer matrix method. It is also possible to improve the calculated results under certain conditions by using the central residual method. In the last part of this paper, an example for calculation on a multi-span shaft is given. It is shown in this example how the ordinary transfer matrix method would fail and how reasonable results could be obtained by means of the correction matrix method. The improved methods presented in this paper would be of appreciable value when we use the transfer matrix method for the calculation of such vibration problems as the unbalance response of a flexible rotor.

传递矩阵法常用于计算多跨转子的临界转速、振型及不平衡响应。由于计算机字长是有限的,从某些转速开始,所算得的振型会严重失真,剩余力矩也会出现不规则的跳动现象,从而使计算结果失败。本文分析了产生这一现象的原因,并提出了用校正矩阵法可以成功地补偿有效数字的损失。经过校正矩阵的修正,可使振型及剩余力矩的计算得到比较正确合理的结果,从而在计算机字长有限的条件下,可以用传递矩阵法计算跨数更多的轴系的高阶频率及振型。 本文还提出了一种中部余量法,在一定条件下也可以改善计算的结果。文章最后给出一个多跨轴的计算实例,从实例中可以看出传递矩阵法的失效及用校正矩阵法修正后的合理结果。 本文所提出的方法,对于用传递矩阵法计算诸如柔性转子的不平衡响应等振动问题时有参考意义。
