Bifurcation shifts in a rotor-stator contact system under frictional forces to higher rotational speeds caused by stator thickness

Accurate simulations of detrimental vibrations observed in a rotor-stator contact system are beneficial. Existing contact models that consider the contact configurations between the rotor and stator cannot deal with the frictional forces simultaneously, thereby not realizing analytical accuracy. Thi...
