Modal analysis of gearbox transmission system in Bucket wheel excavator
of power transmission. In this paper, a special configuration of a gearbox composed of
one stage spiral bevel gear and a two stage helical planetary gear used in a bucket wheel
excavator gearbox is presented to investigate its modal properties. A lumped-parameter
model is formulated to obtain equations of motion and the eigenvalue problem is solved.
The modes are presented in low-frequency and high-frequency bands. Distributions of modal
kinetic and strain energies are studied.
