中文摘要：

在传统的基于扭矩激励的多支承转子系统力学模型的基础上,考虑了轴承负荷传感器和各跨间联轴器刚度及扭矩激励对各跨转子的影响,改进了基于扭矩激励的多支承转子系统力学模型。以一暂态扭矩为例,通过仿真分析了无扭矩激励和暂态扭矩激励作用下,多支承转子系统的振动响应,并通过试验验证了仿真结果的有效性,进而验证了改进模型的正确性,为对多支承转子系统振动的研究打下基础。

英文摘要：

Based on the mechanical model of traditional multi-support rotor system,the effects of stiffness of the bearing load sensors and couplings,and the torque excitation on multi-support rotor were considered,and thus an improved mechanical model for traditional multi-support rotor system was set up. Taking the transient torque excitation as an example,the vibration responses of the multi-support rotor system with and without transient torque excitation were simulated and analyzed,which result was also verified by the experiment. The accuracy of the improved model is checked,laying foundation for the study of the vibration in multi-support rotor system.
