“…The key for simulation analysis is to obtain the accurate timevarying mesh stiffness (TVMS), which has a great influence on the gear pair vibration. The finite element (FE) method [1][2][3][4][5][6][7], analytical method (AM) [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] and analytical-FE approach [23][24][25] have been used to calculate the TVMS of gears. For AM and analytical-FE approach, they can offer a simple and effective way to calculate the TVMS under most conditions.…”

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. Onedimensional (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.

“…Lumped parameter model and the finite element analysis (FEA) just for teeth were adopted in references [1][2][3][4][5][6][7][8][9][10] to analyze the dynamic characteristics of meshing contact transmission with parallel axis. However, the FEA just for teeth is not fully conformed to actual condition of planetary gear transmission in engineering application, leading to that the actual condition cannot be reflected in full scale.…”

Abstract. Dynamic behavior of planetary gear's tooth contact surface in the different location can better conform operation condition comparing to the general gear pair. Nonlinear finite element algorithm was derived according to the basic control equation of contact dynamics. A finite element model of planetary gear transmission in wind power increasing gearbox was proposed considering different meshing locations based on nonlinear finite element solution. The characteristics of stress distribution at different meshing positions were analyzed. A simulation of the meshing process was conducted using finite element analysis. It was shown that node stresses of external meshing planetary gear varied significantly at different position. The analysis provides some useful insights into the performance of planetary gear's tooth contact surface.
