N2 - Based on the nonlinear model of vehicle planetary transmission, the dynamic optimization model is established. This work use a combined objective function, internal and external load sharing coefficients and peak-to-peak mesh forces of second stage planetary are taken as objectives. The structure parameters of transmission shafts are considered as design variables. Finite Element Analysis (FEA) is carried out to obtain the bending and torsional stiffness, and the maximal Von-Mises stress constraint. Innovatively, we propose and introduce the nonlinear characteristic constraint aim at increasing the reliability of optimization. The Isight-Matlab-Ansys co-simulation method is applied to build the optimization platform. Finally, the optimization moel of vehicle planetary transmission is solved by Genetic Algorithm (GA).
