摘要 为能进行轧机主传动系统复杂分支结构的扭振分析和计算,研究了一种基于拓扑网络的扭振分析模型,模型中同时考察了内外阻尼的影响。求解模型的单支和多分支情况的动态响应。对比传统方法,文中的计算算例和仿真模拟都取得了很好的一致性。同时该法的表达便于作为控制系统的输入,为大型复杂机械主传动系统的实时主动控制和故障诊断监测开辟了一种容易实现的工程途径,也为工程中分析解决复杂多分支传动扭振及其类似问题提供了新方法。 For solving the problem of dynamic characteristic of rolling mill main drive system's torsinal vibration on complex-branch system, a kind of topology network structure model of torsional vibration is studied by using system dynamic theory. The new model include internal and external damping properties. In this work, some different typical types of torsional response are calculated and analyzed, which acquired well consistency between the new methods and the classical methods through the calculation example and simulation. It supplies a kind of new ways to calculate and analysis the complex multi-branch drive torsional vibration system in engineer and practice and for solving the similar problems. Also the topology network representation can easy be input for the control system and exploit a new means on real-time control or fault diagnosis monitor for the heavy-duty machinery's main drive torsional vibration system.
