| Abstract: |
| The meshing gear subsystem of bend torsion coupling vibration model,the axis subsystem of elastic bending vibration and torsional vibration model and the elastic box board subsystem of transverse vibration model are established to get the whole vibration model through the bearing multi-dimensional stiffness matrix and deformation coordinate relations between the subsystems.Phase diagram and poincare map are utilized here to get the movement characteristics of gear box system.And vibration energy is also studied by theory of power flow to have a better understanding of the system performance influenced by the external motivation,bearing stiffness,which provides a new analysis method and theoretical basis for vibration control and structure design of gear box system. |
