Dynamic response simulation of planetary gears by the iterative spectral method

Abstract

A planetary gear is modeled in this work. The equations of motion and the eigenfrequencies are recovered. The computation of the dynamic response is made using the spectral iterative method. The procedure is based on a modal approach with developments in the frequency domain. This technique has been successfully used and its convergence was quickly reached. Good agreement was obtained compared with the standard Newmark method. The dynamic response of the planetary gear is given directly in the frequency domain. The inverse Fourier transform gives the time response of the system.
