With the development of vehicle gearbox to high-power-density and high-speed, how to predict and
optimize the dynamic characteristics of vehicle gearbox becomes increasingly prominent. Aiming at the vehicle
gearbox, this paper comprehensively and deeply studies the dynamic characteristics under the multi-boundary
conditions. The generation mechanism of the multi-source excitations triggering the gearbox vibration is analyzed
firstly. The vibration transfer path of the gearbox is explored. Secondly, the engine excitation, the gear meshing
excitation and the bearing support load are numerically calculated. According to the finite element method,
a fluid-solid coupling finite element model of the gearbox body is established to predict the gearbox dynamic
responses based on the Galerkin method and the Hamiltonian variational principle. Finally, the effects of the
excitation condition, oil height and reinforcement forms on the vibration responses of the gearbox body are
thoroughly studied by simulation. The analysis indicates that it not only helps to modify and improve the method
of forecasting the gearbox dynamic response, and also provides the theoretical and technical guidance for the
gearbox design and optimization.
