“…They also noted that the resonance at multiples of mesh frequency can be excited from higher harmonics of mesh stiffness variation and nonlinear superharmonic resonance. Eritenel and Parker [33] developed a nonlinear three-dimensional model to investigate the vibrations in gears. They found that twisting vibrations separate the edges of mating gear teeth causing contact loss.…”

a b s t r a c tThis paper studies the torsional vibrations of wind turbine gearbox having two planetary gear stages and one parallel gear stage. The nonlinear dynamic model developed considers the factors such as time-varying mesh stiffness, damping, static transmission error and gear backlash. Both the external excitation due to wind gust and the internal excitation due to static transmission error are included. With the help of time history, FFT spectrum, phase portrait, Poincare map and Lyapunov exponent, the effects of the static transmission error, mean-to-alternating force ratio and time-varying mesh stiffness on the dynamic behaviour of wind turbine gearbox components are investigated by using the numerical integration method. It is found that the external excitation has the most influence on the torsional vibrations of the wind turbine gearbox components. The mesh stiffness, being another significant factor, has more influence than the other internal excitation source, the static transmission error. The static transmission error has the least influence.

“…Furthermore, the intense vibration and noise will be produced in the transmission [1][2][3]. The design method and the criteria for most of low noise gear mainly focus on controlling and reducing the source of gear internal incentive, that is, the degree of contact state in meshing process deviates from the ideal state, among which the key is the contact surface shape difference [4][5][6].…”

Abstract-The design method and design criteria for low noise gear were introduced. Based on the analysis of gear modification principle, determination of basic parameters and the design of modification scheme, taking SS8-II type quasi-high speed passenger electric locomotive gear transmission as a studying example, the gear tooth profile modification and axial modification were designed. Through the noise detection, it was found that under the same conditions, the driving device noise sound level A can reduce the 6~10dB after modifying. It achieved better noise reduction effect, which can provide reference for the design of low noise gear. It has important value for engineering practice.

“…The twist stiffness fluctuated periodically with gear rotation generating fluctuating moments (shuttling) that could potentially excite vibrations. In [21] the three-dimensional nonlinear vibration of gear pairs was investigated where the nonlinearity was due to portions of gear teeth contact lines. The nonlinear dynamic response was obtained using the discretized stiffness network.…”

A method to simulate residual stress field of planetary gear is proposed. In this method, the finite element model of planetary gear is established and divided to tooth zone and profile zone, whose different temperature field is set. The gear's residual stress simulation is realized by the thermal compression stress generated by the temperature difference. Based on the simulation, the finite element model of planetary gear train is established, the dynamic meshing process is simulated, and influence of residual stress on equivalent stress of addendum, pitch circle, and dedendum of internal and external meshing planetary gear tooth profile is analyzed, according to non-linear contact theory, thermodynamic theory, and finite element theory. The results show that the equivalent stresses of planetary gear at both meshing and nonmeshing surface are significantly and differently reduced by residual stress. The study benefits fatigue cracking analysis and dynamic optimization design of planetary gear train.
