Modelling of high-power geared transmissions with nonlinear dissipative elements

Résumé

High-power speed reducers in marine transmissions usually comprise large wide-faced pinions and gears, often made lighter by bores in their bodies or box-structured webs. With the objective of reducing mesh vibrations and noise, the recourse to dissipative material in the bores or web boxes appears as a potentially interesting solution, which has nearly no impact on gear design. The main objective of this paper is therefore to simulate and analyze the effects of such dissipative materials on gear dynamics. A hybrid gear model is proposed, which combines beam finite elements, lumped parameters and substructures derived from 3D finite elements. Static and dynamic condensations of gear body models are used and the resulting substructures are connected to the tooth mesh model by a specific interface. The dissipative material is simulated by elastic and elastoplastic Masing elements, which connect master nodes situated on the box walls and lumped masses at the box centers. The influence of non-linear dissipative materials on dynamic mesh and bearing forces is investigated in relation to the energy dissipated in the Masing elements. Finally, the contributions of the dissipative material properties, damping ratio and gear web box-structure are analyzed.
