摘要
采用集总质量法、梁单元法和有限元法3种数值方法研究轴承-转子系统动态特性。数值结果表明,有限元法能够高精度地分析系统固有频率和模态振型,为轴承-转子系统提供了设计依据并为油膜力、电磁力支承的轴承-转子系统奠定了理论分析基础。
In this paper, the three methods of Central-Quality, Beam Element and Finite Element are used to study the Dynamic Characteristics of Rotor-Bearing System. The numerical results indicate that the Finite Element way can be used to analyze the inherent frequencies and modes better whereby providing the design base for Rotor-Bearing System as well as creating the theoretical analysis foundation for Rotor-Bearing System supported by oil-film and magnetic forces.
