摘　　要：为探索多分支扭转振动系统振动特性分析的高效建模方法和通用分析软件,本文以单轴直链扭转振动系统为例,研究了其动力学建模方法,推导出了方程,并给出了求解步骤;进而根据节点处的相容条件,研究了多分支扭转振动系统的动力学建模与求解方法,再将这种方法推广到了多分支多节点扭转振动系统;基于上述建模与求解方法,开发了通用分析软件,为工程应用提供了高效有用的工具。通过实例验证了上述研究与开发。In order to develop high efficient modeling methods and general analysis software for multi-branch torsional vibration systems,taking a one-shaft system with multi-rotors as an example,this paper explored the dynamics modeling,equations and the solving procedures. According to the compatibility conditions at a junction,dynamics modeling & its solution of multi-branch torsional vibration systems were studied. And then,the methods and algorithm were expanded to the multi-junction & multi-branch torsional vibration systems. Based on the above research,a general analysis software was developed that can be used as a high efficient analysis tool for tosional vibration systems. The above method and software were tested by an example.
