Dynamic load sharing characteristics and sun gear radial orbits of double-row planetary gear train

Journal of Central South University 2015年第10期22卷 3806-3816页

作者：盛冬平朱如鹏靳广虎陆凤霞鲍和云 College of Mechanical and Electrical Engineering Nanjing University of Aeronautics and Astronautics

A new non-linear bending-torsional coupled model for double-row planetary gear set was proposed, and planet's eccentricity error, static transmission error, and time-varying meshing stiffness were taken into consideration. The solution of differential governing equation of motion is determined by applying the Fourier series method. The behaviors of dynamic load sharing characteristics affected by the system parameters including gear eccentricities error, ring gear's supporting stiffness, planet's bearing stiffness, torsional stiffness of first stage carrier and input rotation rate were investigated qualitatively and systematically, and sun gear radial orbits at first and second stage were explored as well. Some theoretical results are summarized as guidelines for further research and design of double-row planetary gear train at last.

A branched model was established to reproduce the vehicle creeping status and illustrate the mechanism for severe rattle phenomena of a 5-speed manual transmission in this ***,a quasi-transient engine model was founded and the effective output torque with the crankshaft angle changing was ***,the time-varying stiffness of loaded gear pairs was obtained,which was calculated by both bending and shearing deformation stiffnesses through finite element result regression analysis and the contact deformation stiffness through the empirical ***,the branched model of powertrain system considering LuG re tire property and differential characteristics was established to predict the vehicle creeping status and rattle phenomenon of unloaded gear pairs in consideration of detailed drag torque model,and it would make a solid theoretical basis for further research on gear rattle mechanism and vehicle experiments.
