Non-linear modal interactions during rub-impact of a rotating flexible shaft

Kartheek Amaroju et al.

Summary: This study aims to understand the modal interactions between a rotating flexible member and a stationary element using a conceptual model. Theoretical and simplified models were developed, and eigenvalue and bifurcation analyses were performed to identify the participating modes. The results from the theoretical model were validated experimentally.

Stochastic dynamics of veering modes in a symmetric coupled system

P. Likhit et al.

Summary: The study analyzed the dynamic behavior of a coupled symmetric system using both experimental and theoretical methods, determining the statistical characteristics of the frequency response function through stochastic finite element analysis. The influence of uncertainty in individual subsystems on dynamic response was investigated, with findings indicating the potential impact of manufacturing tolerance on shock amplification and system response.

Stability Analysis of Rotor-Bearing Systems under the Influence of Misalignment and Parameter Uncertainty

Xiaodong Sun et al.

Summary: This study investigates the impact of misalignment and parameter uncertainties on the stability of a rotor-bearing system using gPC expansion and finite difference method. The results show that the characteristics of the HDB and the stability threshold are affected by misalignment and parameter uncertainties.
