摘要：Damping performance of the underplatform damper was numerically investigated on the basis of a simplified model of blades with an underplatform damper. The harmonic balance method was employed to predict the blade response in the frequency domain. A simple expression of the Jacobian matrix by means of discrete Fourier transform was proposed, allowing acceleration of the harmonic balance method. Result showed that, the computational efficiency was improved more than 8 times in terms of blade response prediction. The impacts of key parameters, including centrifugal force, damper mass, excitation level, underplatform angle and the rolling motion of the damper, were thoroughly investigated. © 2019, Editorial Department of Journal of Aerospace Power.
