摘要: 提出了一种在时域内分析转子-轴承系统对地震波激励响应的方法,以伽辽金变分法为基础,用有限元法来模化转子-轴承系统,用Newmark逐步积分法求得了响应,通过试验验证了方法的可行性,计算了某一发电机转子对Elcentro波的响应。

Abstract: A method to calculate the response of rotor-bearing system to seismic excitation is presented. A finite rotor element based on Galerkin formulation is proposed to model the rotor, Newmark integration method is used to obtain the rotor response. The method is proved by experiment. An example problem of a generator rotor-bearing system is solved using Elcentro earthquake data.
