摘要：
the bending-torsional coupled vibration math model is established by taking the vehicle powertrain as model, and taking account of the mesh stiffness and damping of the gear and supporting stiffness and oil film damping of the bearing. And the finite element model of the system is established in ANSYS and making the simulation analysis of the damped modal. The influence of the varying-mesh stiffness, system damping parameters and the supporting stiffness of the bearing on the vibration characteristic and stability of the system are discussed, which is the basis of the further forced vibration analysis and the sensitivity analysis.
