摘要:
本文综合了扭振分析的简化扭转单元有限元方法和传递矩阵法,提出一种新的转子系统扭振分析方法——子结构传递矩阵法.该方法适用于各种复杂剖面的转子段,使用简单方便,且不要求大的计算机容量.子结构传递矩阵法将一转子段离散成有限个单元,通过子结构静力凝聚技术建立转子段两端状态矢量之间的关系.文中详细叙述了这一方法,并给出了几个数值算例,结果是令人满意的.
Abstract:
This paper suggests a new method for the analysis of the torsional vibration of rotor system,a substructure transfer matrix method,which combines the of finite element method with the transfer matrix method.It is proved to be effective and applicable for various rotors with complex shapes.By this method,a section of the rotor is discretized into finite ele- ments and the relation between the state vectors on two sides of the rotor section can be established by the technique of substructure condensation.The detailed description of the presented method is given with several numerical examples, the results of which is satisfactory.
