本文提出的传递短阵阻抗耦合法,应用子结构综合的概念与机械阻抗数据的耦合,将传统的传递矩阵法推广应用到具有中介支承与异型结构的多转子、多支承的复杂转子支承系统,包括轴对称的与具有正交特性的无阻尼与阻尼系统的固有特性的分析。既可全部用数值计算,也可部分的与试验数据相结合,是一种精度高、成本低、适宜工程应用的分析方法。
In this paper, the transfer short-impedance coupled method, the application of the concept of sub-structure synthesis and mechanical impedance data coupling, the traditional transfer matrix method is applied to a wide range of rotor and multi-bearing complex rotor support system with intermediate support and shaped structure, Including the analysis of the inherent characteristics of an axisymmetric and undamped and damped system with orthogonal properties. It can not only be used for numerical calculation but also partly for combination with experimental data. It is an analytical method suitable for engineering application with high precision and low cost.
