| 双转子系统临界转速的积木式传递矩阵法 |
| |
| 摘 要： | 本文提出了用于具有任意多盘及柔性(或刚性,或中介)支承的双转子系统临界转速计算的矩阵法。本文提出的“标准积木块”新概念,为编制通用计算机程序提供了理论基础。在这种指导思想下,任何一个真实的转子系统都能看成由不同的“积木块”迭加而成,并且计算时只需对程序作非常小量的修改。余数趋于无穷大时的转速并非是临界转速,它是一种数学现象,应在计算结果中予以剔除.

| Abstract: | A matrix method for calculating the critical seppds of a twin-rotor system with any number of disc and flexible(or rigid or intershaft)support was developed in this paper.A new concept of 'stanard building-block' , introdueed in this paper, provides a theoretical basis for managing a general program. In this case, any kind of real rotor system can be seem superposition of different 'building-block' , and just a little modified work is necessary to change the program.The speed where remainder tends to infinity, being a mathematic problem, is not a critical speed. Therefore, it should be cancelled from the calculatiug results. |
