Consideration of Traveling Waves Using Superposition of Vibration Modesestigated thus far. To solve these problems, we proposed abovementioned two methods in this paper. The governing equations when the arbitrary mechanical impedances are installed are theoretically formulated using the substructure elimination method, and the formulations to extract the traveling wave

Rotordynamic Force Coefficients for Open and Shrouded Impellersrdynamic force coefficients using complex impedances. Stiffness and damping coefficients are compared and discussed in order to highlight the influence of the shroud together with the eye-packing seal and front casing on the impellers performance.

Vibration Force Transmissibility of a Rotor-Stator System with Potential Rub-Impactts of mass unbalance level, contact stiffness, and contact friction coefficient on the rotordynamic behavior and vibration transmission characteristics are examined systematically. The results show that the impact contact has a hardening nonlinearity effect on the steady-state frequency response of

C. Nerse,S. Wangalways been, and still is nowadays to some extent ‘mysterious’. . is another Greek word; it means mysterious, but at the same time sacred. The beginning of life has something of the mysterious, and also of the sacred. This permits understanding why it has a religious dimension, which in our Western
