Original abstract

This paper presents an experimental investigation of the dynamic response of a high-speed rotor system supported by aerodynamic tilting pad journal bearings subjected to base excitation. The study focuses on the influence of various operating conditions, including different rotational speeds and base excitation frequencies, on the dynamic response of the system. The base excitation was applied using a controlled shaker excitation, and the system response was measured using non-contact displacement sensors. The results highlight critical speed dependencies, amplitude variations, and damping characteristics under different conditions. These findings provide insight into the dynamic performance of rotor systems operating in low-viscosity environments and serve as a basis for future model validation and optimization.

Keywords in English
