“…Some other studies by Chen et al (2011Chen et al ( , 2012Chen et al ( , and 2013 enhanced understanding of the influence of the friction on the natural frequency of the hot fit rotor-hollow shaft assembly. Chen and Yang (2010) also performed an experimental study of a hollow shaft with a hot-fitted rotor to determine the optimal value of interference for dynamical stiffness of a shaft fitted with a hot-fit rotor. In another study, Asdaque and Behera (2014) analyzed the dynamic behavior of hollow tapered shaft-rotor to investigate the effects of length and speed on the dynamics of the hollow tapered shaft-rotor system.…”

The present work aims to understand the influence of the asymmetries on the dynamics of the hollow rotor system. The study comprises the analytical study through the extended Lagrangian Hamiltonian approach and validation conducted with the simulation study through the bond graphs. This study involves an investigation of the dynamics of the hollow rotor system through two case studies. First case study considers a hollow rotor system with small asymmetry in stiffness while another study considers a hollow rotor system with asymmetry in mass. The lumped analysis involves the development of a mathematical model by considering the symmetry breaking of a hollow rotor caused by mass or stiffness. The study shows good agreement in simulation and analytical results.
