Forced vibrations of gearboxes with time dependent meshing stiffnesses [PDF]
PAMM, 2003 AbstractThe contribution presents the efficient method of the mathematical modelling of gearboxes with time dependent meshing stiffnesses. A gearbox is considered including a housing and an interior rotating shaft system with gears. Further the paper deals with an analysis of vibrations excited by the important sources of the internal excitation in ...
