Abstract EN
This paper investigates the dynamic effects of mass reduction on a pair of spur gears.
A one-Degree-of-Freedom (DOF) model of a mechanical oscillator with clearance-type nonlinearity and linear viscous damping is used to perform the investigations.
One-dimensional (1D) gear pair models aim at studying the torsional gear vibrations around the rotational axes and can be used to simulate either gear whine or gear rattle phenomena.
High computational efficiency is reached by using a spring-damper element with variable stiffness to model the gear meshing process.
The angle-dependent mesh stiffness function is computed in a preparation phase through detailed Finite Element (FE) simulations and then stored in a lookup table, which is then interpolated during the dynamic simulation allowing for high computational efficiency.
Nonlinear contact effects and influence of material discontinuities due to lightweighting are taken into account by FE simulations with high level of detail.
Finally, the influence of gear body topology is investigated through a sensitivity analysis, in which analytical functions are defined to describe the time-varying mesh stiffness.
