Rotor-to-stator contacts can occur in hydropower systems due to mechanical and electrical
misalignment as well as high unbalance forces. It can result in high impact forces and …

Vibration characteristics of unbalance response are the research basis for active balancing
control, which is the important method of vibration monitoring and control. For the motorized …

This paper describes the numerical and experimental investigation of the nonlinear vibration
of a bladed Jeffcott rotor. The nonlinearity in the system is due to discontinuities caused by …

针对透平机械中叶尖碰摩诱发的转子系统振动问题, 基于转子-叶片-定子耦合系统模型,
通过对叶尖碰摩过程的数学表征, 采用谐波平衡法和Newmark-β 法, 分别对转定子的稳态响应和 …

Aiming to the blade tip rubbing-induced vibration of a rotor system, based on the rotor-blade-
stator coupling system model, the numerical calculation of steady and transient responses of …

The nonlinear behaviour of blade rubbing has usually been investigated using complex
modelling for the contact description. However, a simplified model of a 3-bladed Jeffcott rotor …
