分析化工机械转子轴承系统的有限元——传递矩阵联合法

A Unified Approach to Vibration Analysis of Rotating Machinery

提出用有限元、传递矩阵联合法分析转子动力学问题的数学模型,避免了有限元方法的局限性,提高了有限元法的实用性。

A unified approach is developed for vibration analysis of rotating machinery that combines the advantages of finite element method (FEM) and transfer matrix method (TMM), while eliminating their respective disadvantages, It requires less storage allocation than finite element analysis and significantly reduces the computer solution time. However, the round-off error could be a potential problem with this method. Numerical examples are given.
