摘要
提出了考虑并联分支结构的适用于传递矩阵法的封闭周转轮系动力学分析模型。建立了动力学模型中惯性元件、弹性元件和分支节点的动力学分析的数学模型 ,并在此基础上用传递矩阵法建立起封闭周转轮系动力学分析的数学模型。对某航空发动机用减速器进行了动态特性分析 ,求出了该减速器的各阶固有频率、模态柔度和势能分布率等动态特性参数。找出了该减速器的动态薄弱环节 ,为进一步改进其设计 ,提高动态性能 ,提供了理论依据。
The holder link bar is considered as parallel b ranch mechanism in this paper.First,a dynamic model of the closed epicyclic gear trains,which is suitabl e to transmitting matrix,is established.The mathematical models of inertial unit ,elastic unit and branch node in dynamic model are deduced.And the mathematical model for analyzing the dynamics of the closed epicyclic gear trains is establis hed by means of transmitting matrix as well.Then,the dynamic characteristics of the decelerator of a certain aeroengine are analyzed.The dynamic character param eters of natural frequency,mode flexibility and potential energy distribution ar e calculated.The dynamic weak part of the decelerator is found out.So,it can be used as a theoretical reference in further design in order to promote its dynami c properties.
