The model consists of a f inite element model of shaf t structures combined with a three-dimensional discrete model of helical gear sets. Bearing f lex ibilities are included in the model as well. In this study the contact between teeth caused by the backlash is considered. The nonlinear transient solution and the Newton-Rap hson Method are used to p redictf orced vibrations of the system. Results of a trial run of a comp ressor consisting of a helical gear-shaf t-bearing system are also p resentedf or validation of the model. It is demonstrated that the p redictions match well with the trial run data. The results of the study benef it thef ault diagnosis and design of gear-driven rotor systems.
