A universal computational method for obtaining dynamic coefficients of the fixed-tilting pad mixture bearing

A novel and universal computational method is proposed to obtain the dynamic stiffness and damping coefficients of the fixed-tilting pad mixture bearing. The dynamic analysis is carried out on the performance of the mixture bearing used in some F type heavy-duty gas turbine, and the influence of bearing parameters such as eccentricity and perturbation frequencies on those dynamic coefficients is studied.
