To reduce the risk of fatigue problems and flutter phenomena, the structural damping of
turbomachinery components is increased by integrating constrained viscoelastic patches …

The rotating shafts are an essential parts of any rotating machineries. Their dynamic
behavior usually receives substantial care in the design stage of rotating machines …

A two-field version of the floating frame-of-reference approach is developed to describe the
dynamics of a flexible body in the case of motion in a uniformly rotating frame. Full …

In this work, a novel methodology for the identification of stiffness and damping rotordynamic
coefficients in a rotor-bearing system is proposed. The mathematical model for the …

The paper considers the issues of adequate mathematical modelling and numerical
simulation of rotor dynamics processes in machines and systems with rotors in various rigid …

The following article presents the elaboration and results obtained from a 3D finite element,
of the 8-node hexahedron type with 6 degrees of freedom (DOF) per node (48 DOF per …

Hydropower generators withstand multiple forces from diverse sources during operation. To
ensure their stability and safe performance, numerical tools are developed to characterize …

The article includes the comparison of two methods of modeling and evaluating the
dynamics of rotors in active magnetic bearings (AMBs). An analysis of the dynamics of the …

Bearing is one of the fundamental components in the mechanical system and sometimes, it
works for a long time under extreme conditions of high speed, which inevitably induces …
